SOURCE: My 1999 Chevy Tahoe wont start unless i spray

It is not a fuel pump problem.
It a cold start valve problem. It didn't open. There are 2 things to check.
1- The cooling thermal sensor is not sending the proper signal to the ECU to turn on the cold start valve.
2- The bad solenoid inside the cold start valve causing it not operational.
Case 1 you can easily replace the thermal sensor.
Case 2 checking this requires professional skill to confirm if there is a signal at the valve during the start.
Good luck

SOURCE: Took my truck to AutoZone, got a 0300 code, now truck dead, what to do?

Ok PO 300 is A RANDOM MISFIRE meaning that mre than one (1) cylinder is misfiring and the computer cannot tell which ones. Ok having said that I used to own Ace Automotive in Lakewood Washington for 14 years i specialized in Diagnostics and Emissions. I Cured so many PO300 codes with the one thing that everyone overlooks. The fuel injectors, they are either shorted in which case you need to replace them, or in most cases dirty and mo amount of in the tank cleaners can do it. you need to have them professinally cleaned where the fuell pump is disabled and the truck is actually running on the chemical cleaner. We used to use BG products best stuff I ever seen brought many a car back to life I have used and seen the MOTOR VAC system a cannot say it compares to the BG system. Someone will need to determin if any injectors are shorted or dead and replace them and if thats the case just take em all out and have them ultrasonically cleaned they will give you a before flow report and an after cleaning report.
If this information is helpfl please give a good rating and by all means please visit my website and check out the BLOG AND FAQ read all the fuel injector problems .
Thanak you Randy

Please call me its easier to explain on the phone, in the mean time try something easy hit the fuel pump on thebottom with a brick or rock then have someone listen to the fill neck of the tank for the two second "buzz" as soon as you turn on the ignition, has this vehicle been run way way low on fuel many times or the fuel filter neglected to been changed at the 15,000 miles interval?

SOURCE: chevy astro van turns over but wont start when

Check to see if the fuel pump is kicking in,
when you turn the key on without starting the van you should hear it kick on for about 2 seconds,

It could be...
A clogged fuel filter...
Blown fuse for the pump..or bad pump relay..
No gas
Bad fuel pump

Do you have the fuel tester hooked the in the overgrown air valve on the fuel rail in the back of the engine? Or do you have the fuel line unhooked in the back and hooked to the pressure pump? You want the fuel pressure to be in that 60 lb range so if you are hooked into the pressure valve on the fuel rail allowing fuel to go through, then I am betting it is the fuel pressure regulator. To get to that, you have to take the throttle body off and take the plastic plenum that covers the injector packs. On the back of the mount where your six pack of injectors are sits the pressure regulator. If it is faulty then it is dumping fuel instead of holding the pressure like it should.
Get a Chilton or Clymer manual and it shows you in pretty good detail how to fix it. I've done it to my 98 S10 with the same engine.

If you unhooked the fuel line so you are losing pressure from the line back to the pump then I would say your pump is letting fuel back to the tank when it shuts off. My money is on the first possibility though.

Good luck

Where do I spray starter fluid in an 05 chrysler pacifica..ran out of gas and hoping it will start with the spray..did put gas in


Remove the air intake from the air filter container to the throttle body. Use only a quick shot of starting fluid. Can you hear the fuel pump run? Power cycling the key should get fuel flowing and is safer than starting fluid.

Which senser controls the starting of my chevy s10 it will not start


There is no sensor that controls starting. No starts are usually from lack of gas or loss of spark. That is, if the battery is strong enough-charged up enough-that it will crank the engine over.
If your engine is cranking over, check for a fuel problem: spray some starting fluid into the air intake-take the big air boot off where it connects to the engine and spray a shot or two of starting fluid in there. Then try starting. If the engine fires a bit and tries to run, then you know it wasn't getting gas. You will then need to test and check if the fuel pump is working and putting gas up to the engine.
If the starting fluid made no difference, then checking for spark would be next-maybe the ignition system has a problem.
Let me know what you found out, and we can go from there. Have any repairs been done recently? What year S-10, what size engine, and how many miles? Did this just start happening? The more you can tell us, the better chance we have of helping you.

Where is carb on a 98 chevy cavalier


Well it doesn't have one. GM cars built after 1988 are fuel injected.
You could check fuel pressure with a gauge, and also try using starting fluid sprayed into the intake hose to boost fuel supply.

Cranks, why no start?


Usually because of an ignition or gas related problem. You need to check for spark at the plugs and for gas at the engine.

A quick method to check for a gas problem is to spray some starting fluid into the air intake on the throttle body. Take off the big boot from air filter housing to the engine, spray a shot of fluid into the engine, then try to start it. If it fires up and tries to run from the fluid for a few seconds, then you know it is a fuel problem. Maybe the fuel pump has quit working, or the fuel filter is clogged. If both are good, maybe a fuel injector circuit problem, less common but possible.

If nothing happens from the starting fluid, it may be ignition related-not getting spark. Pull off a spark plug wire from a spark plug and hold the plug wire end terminal about 1/4 inch from an engine bolt or ground. Have someone crank the engine over from the key and watch for a consistent, blue, snapping spark. If no spark, test a few other plug wires to verify no spark at all. So it is not just one ignition coil not working, but none of them produce spark. No spark means the ignition system needs diagnosing. Sometimes it is the ignition control module that goes bad-it can be tested at any parts store. Post back and we can go from there.

96 chevy s10 v6 stalls after i start it up


This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

My car has been sitting for 2 years and won't start. The engine turns over but it sounds like not getting gas. I read somewhere to spray gas starting inside air intake valve. Where is the air intake v


Safer is to use 'carburetor cleaner' which is also flammable but a little less dangerous than using gasoline.After sitting a long time, our modern gasoline gets tired; never allow something to sit so long without adding some 'fuel stabilizer.'If possible with your car, I would drain (siphon) the tired gas out and replace it with a few gallons of fresh.
Really tough starting problems can also be overcome with 'starting fluid' which is pure ether and very flammable.Any of these may require the removal of the engine air filter so the liquid gets into the intake manifold.
Stale gasoline can also gum up the fuel injectors which may have to be removed for service if none of the fluids causes the engine to fire.

I ran outta gas on my 1998 chevy silverado v.6 vortec. i put more gas in it and pumped the accelerator a few times and it still wont start. how can i fix it is it simple


Best way to fix it when you run out of gas is this. Because you ran out of gas, means your fuel filter is out. When you run out of gas, you end of getting like a air blockage in the line. Now, professional way is to take fuel filter off and fill with gas and put back on, BUT i will tell you a back yard mechanic secret way. Is get a can of starting fluid ( you can get at any auto parts store) and while someone is in side the Pickup, have them ready to turn the key. You are outside with the hood up, and you will be spraying a little bit of the starting fluid in the air intake of directly in carb area ( if carborated) but just spray into air intake. Have them crank the engine, at same time you will spray starter fluid in air intake, just a couple of quick sprays. You will notice it will start and maybe die again. That is normal, you might have to do this a couple times to get things flowing. HOWEVER, what normally happens when you run out of gas, the fuel filter picks up all that junk that has been gathered in the bottom of fuel tank and it has clogged your filter. FOR SURE, if you replace your fuel filter, it will solve this problem. Thank You, and I hoped this helped you.
