91 olds cutlass supreme-runs good for days and then all of a sudden while driving it stalls out. I turn the car off restart and then either it will run good or else it stalls four or five times. Then it will run good for days.

There is a red wire close to the battery in the front. It's not connected to anything. Apply positive voltage and that will run your pump for testing purposes.

TRY CHANGING FUEL FILTER,COULD BE CLOGGED FUEL FILTER,FUEL PUMP FAILING,FUEL COULD BE CONTAMINATED WITH WATER.IF FUEL SYSTEM OKAY,CHECK FOR SPARK AT SPARK PLUGS,COULD BE FAULTY IGNITION MODULE OR FAULTY IDLE AIR CONTROL VALVE I WOULD HAVE VECHICLE CODE SCAN FIRST BEFORE SPENDING MONEY.

You can go to a nearby parts store and purchase a Haynes automotive reference guide and it contains all the different diagrams that would need. On the front of the book it would say 1990-94 lumina cutlass etc.

engine quits when you let up on gas pedal

You will need to change the crank position sensor first and see if it corrects the problem. It is located behind the engine near the firewall. It's a bit tricky to get to it, you would need to rotate the engine forward then look under the exhaust manifold and under the cylinder closest to the drivers side. Use a 10 mm deep socket to loosen bolt. After replacement and it is still stalling then you will need to replace the ECM (vehicle computer). If it turns out to be the computer, go to your local junkyard to get an inexpensive replacement Click on the link below to view the CPS, it is around $22
