I have a 1995 Chevy Beretta and it has the 3.1 in it. I can drive the vehicle when its cool outside all I want but once it gets about 70-80 degrees outside I have the worse car ever. The fuel pump will start making a whining noise (which I already changed thinking that was the issue) then about 15 minutes of riding the car will just DIE out and we have to sit on the side of the road and just let it cool down so that we can start it again and be able to ride about a mile or so before it does it again...... No check engine light comes on at all...... any help is much needed right now. Thanks.

 

On your link you state the check engine light comes on when it stalls? Does it stay off after you restart (after the time it takes?).

 

No... the check engine light doesn't come on at all..... It only dies out on really hot days.... The fuel pump has started whinning and everything BUT we just put a new one of those in... also, you can push the gas to the floor and its like you can feel the car just cutting out.... it will spit and sputter...

 

after it stalls the check engine light comes on... but once the car restarts the light goes off....

 

Test the car, start it up let it idle until it stalls, do not drive it, sit there and watch it run till it stalls.

Now, once it stalls, open the engine hood, and check the spark plugs for spark.
To do this easily, pul a wire off a plug and put it near a ground. Have someone crank the engine, if there is a spark happening, the ICM is fine, if not then there might be a bad IM or coils, or both.

BUT, if there is no spark, and you think it is the ICM, have it tested before replacing it. just in case test it a few times.
Also, it might be the CPS in the back of the engine block. they go bad with age. but BE CAREFUL, they get brittle and can get stuck in the block broken. Remove carefully.
Between the ICM and the CPS its a toss up if there is no spark.

However if it stalls and there is spark.
It might be a bad fuel injector, they change resistance with temp, when they get old, if they get too far out of range, the ECM is designed to turn off the injectors to prevent engine damage & ECM damage.
An easy way to check if your getting spark after stall and it wont start, is to remove the front three spark plugs, crank it a few times, and small for gas. If there is gas, then the injectors might be working, and they might be stuck open/closed from dirt/age. (which is HIGHLY unlikely).

Now the above is if it stalls while driving.
If it stalls only after you stop while in drive when driving, then the above is not an issue. read below:

In that case an easy test is to put in park or neutral. start the engine, if it starts, then put in drive and see if it stalls.
If it stalls it is a bad TCC solenoid. if not, unplug the TCC solenoid and drive it around to see if it stalls again. if so, its a problem like above. if not, its probably the TCC solenoid.
