Question about 1988 GMC S-15

1 Answer

1988 gmc s15 2.5l 5spd/starts strong then dies

This only happens when weather is both wet and cold.Have replaced cap&rotor,oxy &throttle posit sensor,plug wires,oil relay,fuel filter,map sensor,pcm,egr. checked and cleaned all connections i can find.Something seems to be telling it to stop sending fuel.Runs fine while spraying aerosol into tbi until the can runs out.Runs about 10 seconds till it dies. Over and over again. Diagnostic machine claims there are no issues. If brought inside for a few hours it will start and run fine. Please help. Thanx.

Hello: I would check the fuel pressure when this occurs, this year model should have throttle body furl injection. 10 psi should be the nominal fuel pressure. Check the fuel filter. When it quits does it just shut off or does it sputter a little bit then quit, if it just quits it could be ignition, hei coil, module, pick up, check cap and rotor, rotor for a burn spot close to the distributor shaft

I have a 2.5 in a 91 pickup , it dies at idle and spits and sputters until the engine warms up ,it throws no codes,it has 170 thousand miles and still runs strong after warming up

how are the tune-up components,if they need replacing this can happen as the extra fuel when cold puts more stress on weak components.(plugs,wires,cap,rotor,air filter,etc)it could also be carbon build up on the back of the intake valves,this can cause the carbon to absorb fuel(like a sponge)until either the car warms up or the carbon is saturated.this can cause a lean condition when cold.the way to correct this is to have a top end fuel service were a chemical is run through the motor to break up the carbon and clean the intake surfaces.

starting definately has a lot to do with the crank/cam position sensors, but it wouldnt have nothing to do with hot or cold weather, oxygen sensor will make the vehicle run too rich if its out, you will smell fuel very strong out the exhaust, that could make it run sluggish also, and usually if the mass air flow sensor goes out the vehicle wont start at all...

Hey, I think you are looking in the wrong area. The 5.7l distributer and rotor buttons are prone to getting wet. You need to remove the cap and clean the rotor, distrib cap and any internal components you can see. Good luck. Also check the plug wires to see if they are wet. Cheers

im not sure if it is your problem but i would try replacing your throttle position sensor on the throttle body. it has a simple two wire conector and two torx bolts. mine was cutting out and stalling and sputtering and that was my fix
