Question about 1988 Chevrolet Suburban

1 Answer

1988 Suburban 5.7l will turn over but won't start

Had this happen the other day and a friend of mine suggested putting a little gas in the carburetor...seemed to solve the problem, so we assumed the jets were clogged. Now it's happened again, and this time we've put gas in the carb, even changed the battery because we thought it may not be getting enough juice to turnover (another problem we had about a month ago), but it still won't start. Is this the fuel pump or filter? Or something else? I've noticed that the gas gauge is generally not very accurate, but we made sure it had a sufficient amount of gas in the tank. Thanks!

    sounds like the seals in the fuel pump lets the fuel drain back to the tank this truck should be tbi in that case you should be able to hear the fuel pump kick on when the key is turned on

I just replaced my wires, plugs, rotor and distributor cap in my 1988 suburban and it initially backfired and I rechecked to make sure that the wires were on both ends properly and they were. Since then it...


It sounds like thw firing order's wrong, rotor might be positioned wrong, or the distributor is off a notch. The distributor cap might be 180 degrees off as well.

1988 chevy S10 turns over but won't start getting spark put in new fuel pump,cpu and injector. If I pour A little gas in throttle body hole it will fire for a few sec. fueses all test good.


Hello, just had this problem myself. Check your EGR valve by pulling the vacume line off and pushing up under the valve put your finger over the vacume line hole and release the valve, if it returns to normal position then its bad if not its good. If its bad it needs replaced. Mine did the exact same thing and thats what it was. Hope this helps

My retractable running board on the drivers side of my chevy suburban sometimes won't drop down. You can open and close door several times and it finally will work. The dealership doesn't know how...


I've had numerous issues just this summer with my 2008 LTZ Suburban. The dealership has replaced the battery, some module and, it's back in as we speak to have both runnimg board motors replaced because they both locked up again! A friend of mine owns a 2009 LTZ Suburban and has started having intermittent problems with her running boards, too. When it's time to up-grade, I will NOT be getting retractable running boards again!!

I would try to get a fuel filter first and replace that if that isnt it you probably have a issue with the fuel pump. also try taking a hammer and bang lightly around were fuel pump is located in the gas tank.If you have a issue with fuel pump and dont no how to drop tank and replace it you would be wise to shop around because it could save you hundreds of dollars.

1988 Volvo 240 DL won't start B230F


I had more or less the same problem. It would only happen when the engine was cold. According to the mechanic, the fuel pump was going bad. After replacing it, I havent had it happen to me again, granted its only been a couple of days since I changed it.

1988 5.7 TBI Nightmare This is the start of what the problem was and is, I had a RV cam installed when the engine was rebuilt a year ago. the cam was not a computer friendly cam so after a round with the rebuilder and discovering the specs weren't the correct ones for the cam I installed a 3702 edelbrock cam and lifters with a 7800 timing chain and gear set after I had tried two chips from Jet and no improved performance and the 3rd chip was to be for the cam and that is what is in the ECU now and I have tried about 5 different BCC chips and the bottom line is the power is there but something is happening its hit and miss the idle will sometimes lope, is stalled when first started and acts as if its starving for fuel or its bogged with to much fuel. the fuel pressure is 10 - 13 psi and I have R/R the TPS, IAC, ESC and knocks device , EGR and Solenoid, MAP, Temp sensor, and the Dist is a Procomp 10001 with a MSD-5526 coil. the Throttle Body was rebuild and the ECM was replaced with a Rebuilt ECM. it will smell rich etc. but with the things that goes on it does not show any codes?? I have no clue just feel stupid this is been a simple thing that is kicking my **** and now its a challenge but still loosing the fight too far in and too much spent to stop,. LOL Help !!!! The BCC is a california vehicle AFBX, 5.7TBI TH400 A/T P.S. the key can be turned of and back on as the engine not dying and seems to correct the power and run problems but will not last goes back to running bad or with problems. ?
