    Please list all the repair work done to try and repair this problem, it saves us guessing and suggesting you replace parts that you have already installed. Thanks

    How did you try to test? does the check engine light work when the key is first turned on?

  • missy and john Nov 10, 2011

    yes the check engine light works. the auto part store even tried to test it and got no codes

    THE AUTO PARTS STORE CAN'T TEST THIS FOR CODES, IT IS AN OBD1 ELECTRONIC ENGINE CONTROL SYSTEM SYSTEM, THEY HAVE A OBD2 SCANNER, TOTALLY DIFFERENT ELECTRONIC ENGINE CONTROL SYSTEM. THIS APPLIES TO ALL THE DISCOUNT AUTO PARTS STORES I AM AWARE OF.

  • missy and john Nov 10, 2011

    I am in Florida. No one hit the truck

  • Justin Fitzgerald

    @saa_aa- the fuel tank is not responsible for the delivery of fuel to the motor, please keep useless information and inquiries from the thread as it confuses those that are working on this question.

  • sami
    sami Nov 10, 2011

    Ensure the fuel tank is OK .
    cool aim from lady lake , Florida , i would like to meet with you and see your car .

    .I am of your voice that you know very well what you do and that's good to talk to you could make easier to get around the problem.

    A fuel pump can be faulty and cause trouble starting. try install a fuel pressure gauge to see if the pressure is ok morning when you try to start the engine. and see the pressure after the Onegin is hot .
    and make sure the fuel tank is OK .
    good luck , and let me know , thanks

  • Justin Fitzgerald
    Justin Fitzgerald Nov 10, 2011

    @saa_aa thats what I was referring to, if you would have taken the time to read all the other posts, you would know that both the fuel pump and filter have been replaced. and as for the tank, once again there is no connection to that in regards to fuel delivery.

Hello! This is Saailer at your service...You have to many solutions for any human to deal with...FIRST...Tell me what engine is in the vehicle; Be specific...SECOND...The "check engine light" on your suburban will be the brake light in the speedometer cluster. There is no actual check engine light on your model...Your vehicle is On Board Diagnostic I (OBDI)...There is a plug called the ALDL connector...See picture below... It is located on the drivers side mounted on bottom of dash or back up under it... Short A and B together with a paperclip or wire; With key on engine off and watch " light for blinking... Each code repeats itself 3 times....Example: "blink" pause "blink" "blink" is code 12 "blink" "blink" pause "blink" is 21...Remember each code will repeat 3 times then go to next code if you have many codes this will take a while be patient...The last code is 12 Code 12 is always the first and last code, this tells you that it is in diagnostics (first 12) Last 12 means end...Go to the link below for a list of codes...When you have a code/codes send them to me and I'll take it from there...Guru..saailer

  • David Burbee

    Hello! I appreciate your effort to retrieve a code...I really expected that there would be one...So the latest is that you've replaced the computer and the problem appears to be solved? The 1989 Chevrolet never won any prizes for their software finding and storing trouble, but hope burns eternal...The bottom line is the hope that the bug is gone...

Sounds like it's leaning out this causes the rev up.. it's a fuel problem check the filter. i take them off and with my fingers on both ends of the filter i shake it vigorously and dump the remaining fuel out of the filter on the driveway too see what is in my filter, do this every time and you know after the second time how often you should be changing your filter.. suburbans like there fuel and need frequent filter changes.. around a 20 fix if yo do it yourself ... jay florida

Wow! This seems to be a record on replies. At this point, I would (try) to drive until the tank was close to empty and then drop, and invert it. This sounds an awful lot like heavy particulate stuff in the tank that drops off when the pump isn't pumping and is then picked up again until too little fuel can pass through, gagging the engine.
An old Isuzu/Chevy LUV we bought at a DEA auction had the remnants of plastic film that had been used to wrap pot for smuggling into the US.After the tank was pulled, we found maybe 10 sq. inches of the stuff that had caused the problem.
Good luck!

    If you have not replaced the EGR Valve do so. My Jeep did this very thing and I replaced the EGR valve...problem fixed Jeep ran perfect. If this does not solve - make sure the air filter, fuel filter, are new - make sure no vacuum lines are broken, loose, off - or cracked - Also, look for and check all fusable links - my 90 F250 would cut out and die...after replacing part after part after part - I found a fusable link that was loose...I connected it, and never had this issue again. Also, something that will do this is a dirty or bad Mass Airflow Sensor (MAS).. first, purchase MAS cleaner from your local parts dealer - remove the MAS (located on the air intake hose, from air filter to intake, about midway; small black box with wiring harness coming out; for newer vehicles, they are smaller and they screw into the side of the airfilter casing). Remove and clean - spray very genersouly and let air dry for 10-15 minutes - then re-install, connecting wiring harness, and putting air filter casing back into place securely. Start engine, let idle so the computer will detect the sensor, then drive vehicle. Please let me know if you need further assistance.

An 89 Suburban would be difficult to get codes from considering that it is either OBDI or OBD0. That out of the way you should be focusing on the issues you have corrected and looking a issues that older vehicles have.
I am going to provide you with a check list of things I would look for if this vehicle was in my garage;
1. fuel lines.
2. fuel flow.
3. fuel volume.
If these Items check out then I would move on to the stalling conditions. When does it stall? Cold starts, Hot starts, After a few miles? Only on Take off? When the vehicle is shifted out of reverse/ into drive and vise versa?

These items need to be addressed before I take any thing into consideration. Let me know what you have and I will get back to you promptly.

ZiM

On a side note, I believe this is the throttle body injection motor, In which case there are a plethora of issues that can resolve a stalling problem, and why I need such thorough input from you.

    it stalls when you are in gear i can be going 45 mph down the road and it will stall i can be pulling out of my driveway and it will stall sometimes when i put it into neutral to restart it then back to drive it will stall it dont matter if it is a hot start or cold start fuel lines fuel flow all seem to be good sometimes it is a few miles other times it is about 20 miles i can usually shift it without it stalling

  • Justin Fitzgerald
    Justin Fitzgerald Nov 10, 2011

    Am i correct in assuming that you have an automatic transmission? I forgot to inquire that also, as this may play a roll in the stalling issue.

  • Justin Fitzgerald
    Justin Fitzgerald Nov 10, 2011

    Also the more i read about this issue the less i think it is a fuel problem....

  • missy and john Nov 10, 2011

    Yes it is a automatic

  • Justin Fitzgerald
    Justin Fitzgerald Nov 10, 2011

    On a lighter note, I think that you may have an injector issue or a leak in the manifold. The best way to eliminate this as a possibility is to spray the intake ( around the gasket) while it is idling. if there is a leak of any kind the idle will fluctuate. As far as checking the injector (which I would remember them as a "crab injector") they go bad all the time and create all types of drivability issues. Rough idle, bad idle, rich/ lean conditions etc. If you test the intake and it is in good standing then we should move onto the injector and see what we can get from there....

    Look forward to what you got,

    ZiM

    My dear friend Justin , the fuel tank plays an important role in this problem, believe me .

  • Justin Fitzgerald
    Justin Fitzgerald Nov 10, 2011

    @saa_aa, Go on you have my attention at this point? In what way does the fuel cell have ANY thing to do with fuel delivery?

  • sami
    sami Nov 10, 2011

    Sir, as you know that inside the fuel tank barriers like rooms and These rooms have to keep the fuel full always .

  • Justin Fitzgerald
    Justin Fitzgerald Nov 10, 2011

    There are very limited makes and models that have separated fuel cells. The Checy Suburban is not one of them, also there would have to be a small animal in the fuel tank to "clog" one of the "anti slosh" panels. Once again this also would not give a " stall and immediate restart" condition. With all the input that I have gotten from the asker, I believe I have given all the correct advice with accurate details.

Sounds like to me the throttlebody might be worn out I would either rebuild or replace the throttlebody.The throttlebody houses the fuel pressure regulator which its self could be bad.You can get a repair kit from www.rockauto.com for about $30.00

Did you replace the fuel pump pump connector at the top of the fuel tank?? It is a known problem, the connection gets hot and the connectors inside the plastic shell loosen up, this causes a loss of voltage to the fuel pump at times and a lean condition causes the stall out with the momentary rev up of the engine just prior the stall event. Also the ECM computer control module can be defective as well as things like corroded grounds and problems in the engine end of the wiring harness, none of these problems will leave a ECM fault code when they act up.

Exactly as Jay says but DONT dump it on your drive !
It wille at ashphalt !
Also do it on a clean paper towel in a tray as this often indicates what type of contaminant you are getting.
EG. water, metal (rust), dirt etc.

Since there is no check engine light lit, I tend to believe that it is a problem in the fuel system. It is the only system that can cause shutdown without setting a code somewhere. As I recall, the TBI units ( looks like a carb, but has a single, or double low pressure fuel injector inside instead of a venturi ) use a pressure regulator in the return line that can fail. when this happens, the fuel pressure drops and the car stalls. In some GM TBI systems the fuel pump connects to the steel fuel line with a short section of rubber hose to dampen motor noise. I've seen a situation where the rubber section became cracked, preventing the injector from recieving enough pressure to operate. This problem presented itself as stalling out when trying to pull out from idle under load.

Try cleaning the throttle body out. then remove and clean the Idle Air Control valve. this may help. as long as you are getting fuel. also check for a vacuum leak in hoses or the manifold itself. good-day ! make sure air filter is clean and free of dirt. you may want to clean manifold air flow sensor also.

Wow, you certainly received many comments about your problem. I will provide a link address for used parts for your older vehicle. Car-parts.com is a listing service that is free and can be International as need be. You put in a FREE request for a needed part and you get a contact list, sometimes photos, prices, parts grade, and all the Contact info you need. Parts are shipped to your door, some have limited warranties. If you need a fuel box, body parts, this may be helpful in the future.

It would not take much to check the Coil as they can short out intermittently, but would not cause an engine to REV up. The inducer pickup in the distributor can do that as some of the engine controls rely on measuring Resistance in the circuit and having a failing component overheat can produce all different kinds of resistance.

Would like a post when you finally find the problem.

Need my head under the bonnet and a drive to be honest to pass an opinion as american vehicles have a lot more on them for this age than ones i work on in europe but have you looked at the wiring loom as some american cars and quite a few europeon ones as well suffer from the wiring looms -- the insulation on the wires breaks down and crumbles up causing all sorts of weird and wonderfull faults .just like this

Have vechicle hook up to a scanner see if torque converter clutch solenoid faulty or torque converter has internal damage.GM torque converters been known to fail. transmission shop has scanner see if torque converter still locked up when you apply brakes torque converter solenoid suppose release cause torque converter to unlock leave over drive to keep engine from stalling out like a clutch type vechicle. when you apply brakes.if transmission okay you have intake leak or if engine not well tuned up cause transmission trouble.

    GM Torque converters have no higher failure rate than the rest of the industry. Where did this information come from? Can you site a source to back up this claim of more than average failures with GM vehicles? Thanks wait to hear from you.

    GM TORQUE CONVERTER CAN FAIL.I HAD 93 CHEVROLET THE TORQUE CONVERTER STAYED LOCK UP IT HAD INTERNAL FAILURE. THE PRESSURE PLATE INSIDE TORQUE FAILED CAUSING ENGINE STALL SOON AS I SLOW DOWN OR STOP.DISCONNECT TCC SOLENOID WIRE HARNESS TORQUE CONVERTER STILL KEPT STALLING OUT ENGINE.I DROPPED OUT TRANSMISSION REPLACE TORQUE CONVERTER ENGINE DID NOT STALL OUT NO MORE IF YOU HAVE HIGH MILE TRANSMISSION SOME TIMES TORQUE CONVERTER OR TCC SOLENOID WILL FAIL THEY WOULD BE ONLY THING FAIL LONG AS KEEP TRANSMISSION MAINTAIN. KEEP FLUID FILTER CHANGED.

  • Jonah Oneal Nov 12, 2011

    BAD IGNITION MODULE WILL CAUSE ENGINE STALL OUT. IT TAKES TWO THINGS TO MAKE INTERNAL COMBUSTIBLE ENGINE WORK. YOU NEED FUEL AND SPARK IF FUEL SYSTEM OKAY YOU COULD HAVE IGNITION ELECTRICAL PROBLEMS ALSO.CHECK DISTRIBUTOR WIRES.PROBLEM HAS TO BE IGNITION SYSTEM IF TRANSMISSION TORQUE CONVERTER WORKING.OKAY PROBLEM HAVE TO BE IN THE IGNITION MODULE MEANT TO SAY COULD HAVE POOR GROUND WIRE AT PCM IF PCM WAS BAD YOU WOULD GET A CODES CODES 51 CODE 52

I had a 94 come in and it turned out to be the engine control box. when this little guy started to go it would wait till the truck got warm and just dye. It never set a code and it gave no signs of when it was going to dye, i just know when i sprayed throttlebody cleaner in there it would run....Long story short it fixed the problem.
best luck to you

Try re entering vehickel information into code reader,i just did this with my 1988 GMC pickup, which does have a service engine soon light in the instrument panel.
I first tried scaning by just pluging the scaner in( at the adl connecter) it asked me to check to see if cabel was connected and key was on, (service engine soon was lit)
I tried two, or three, times, same result.then i chose the menue on the scanner selected the correct information concerning my truck+8th digit in vin #.
after i did all this the scanner showed me the codes and told me what they were.
The parts store told me they couldn't scan an auto older than 1996, so i bought my own which can read both OBD 1, and OBD 2,( they were selling them at the same parts store)
You might try seting the scanner up this way,maybe then it will show the codes for you.
also check the wiring on your engine for lose plugs,or connectors, and look or lose or broken hoses as well.
I hope you find it!

Since youve tried every thing with fuel pump.This would seem to be a problem
with electric to throttle body or injectors that control fuel flow.THE Speeding up of the engine would indicate leaning of fuel before it shuts off. check electric and make sure injectors or throttle body are not clogged
Hope This Helps

If there were no impurities found in the fuel filter then it's not likely dirt but it could be water. So if there's allot of fuel in the tank add some fuel treatment for water removal other wise drain the gas and replace with new gas. And if problem continues Check the distributor cap for damage and moisture then Also check the spark plug wires. One at a time for wear, damage etc , and check out a plug or two, be sure to use the rubber boot to disconnect the wire. Check inside the boot for corrosion and pull the plug with correct fitting socket wrench. Once plug is free check it for carbon build up, oil etc. Also check the emissions control label under the hood usually above the radiator for gap specifics. If it's basically clean and gapped right just replace plug then wire. And continue checking other wires, if you don't run across a bad wire and the plug you first pulled was good no need to pull more plugs.

1990 350 suburban keeps stalling when at stop lights seem to idle down then stall


clean your throttle body.
check for codes; you might have a map sensor problem, or your tps might have a dead spot. 9 times out of ten it is a dirty throttle body; the iac can't react fast enough to regulate air when the small gap adjustment of the throttle body gets contaminated with a tarry buildup.

MY 89 4X4 BLAZER BACKFIRES IN THE ENGINE HOW DO I FIX THIS


The backfire could be a problem with the distributor cap or plug wires, or lack of fuel. The cap or wires could get damp and short out until the engine gets hot.
The fuel pressure could be low or not steady until the engine warms up.

Suburban stalls while driving after running for 15-30 minutes. After letting it sit for 5-10 min it runs fine for another 5-10 minutes, then starts doing it all over again.


a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,

the pcm may have a cracked board, i had an 88 cavalier z24 with the same problem, replced the ecu and it ran fine, the problem is that the boards inside the pcm crack and lose connection, the next time it acts up open the glove box and try tapping on the pcm, if the car responds at all, the pcm is bad
