1997 Chevy Express van stalls when warm

I've replaced the fuel pump and filter twice now, and just recently the engine control module (computer). The thing runs great until it is warmed up, but sometimes it will chug and stall when going down the road. Other times it will not. It does not need a tune up or ignition control module. When it stalls, most times it will not start again and acts like it's not getting fuel. If I let it sit a while, it starts right up. Could this be another bad fuel pump, or maybe a bad pressure regulator?  This is driving me crazy, and my wife is all over me to make this thing reliable again. Please help!

SOURCE: 1998 Chevy tahoe Hard to start when cold

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

My gmc 4.3 stalls when warm and wont start without ether. then it runs fine


I had the exact problem with my 1993 chevy c1500. I found that the IAC was sticking so the engine would die at idle after warming up and the ignition module was pulsing the ECM intermittently after the engine warmed up so the fuel pump wasn't being turned on after the engine died....I replaced the ignition module and the IAC valve and all is good. I don't know if testing the ignition module reveals that it isn't sending pulses to the ECM.

When my 92 chev van Lumina gets warm it stalls and won't start till It cools down. What could the problem be.


You'll need to get more information. Find an auto parts store that offers free engine code readouts and have them tell you what the engine computer has detected. This will shorten the long list of possible causes. Post again with the results - you may get to post your own solution.
I've had a bad fuel injector driver transistor in the computer (throttle body injection) and an ignition module do this to me.

92 grand caravan starts poorly, then runs ok when warmed up, then poorly after 30 min. to 1 hr. of driving. Then stalls and won't start till 30 min. or so later.


Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Start with the simple and replace the fuel filter, a dirty fuel filter will also cause what you have described and a ICM (ignition control module) going bad will also do the same.

You can remove your ICM and have it tested free of charge at Auto Zone or Parts Source when you go and pick up the fuel filter. A bad ICM will cause your engine to stall out and eventually fail totally and your going to have a no engine run situation.

On our 1997 express van there is no fuel getting to the engine, however ther is fuel at the filter on the frame rail. Why is the fuel not reaching the engine. The van will start if we add fuel by hand.


the lines might be kinked or clogged. have you ran a curb recently? also there should be no fuel on the frame rail, you have a leak. that is a most likely cause

1989 chevy g20 STALLING


Normally on chevy ignition modules when they go bad, they will quit when they get hot & after cooling down will work again, so when you have them tested they have cooled down. I would try changing it & see if it wont fix it.
