Question about 1991 Chevrolet Caprice
I started the car up to go to work one day, I got about 1/2 a mile from home when I lost power. I pulled into the nearest gas station and let it idle. I could smell raw gas and it was running rough. I turned it off and tried starting it again. This time it seemed to run almost normally, so I cut it off again. This time when I tried restarting it, it just turned over and didn't fire. It has a new distributor, ignition module, and fuel pump.
Could be an air flow meter or faulty pressure relief valve.Try squeezing flexible fuel line before fuel rail with appropriate tool that wont damage the line and see if there is any improvement.obviously allow just enough fuel through the squeezed line so engine continues to run.If it appears to improve you will have to replace pressure relief valve.If its a vacuum controled valve check that you a getting a good vacuum supply.You may also want to put a bottle/can of injector cleaner in fuel tank to clear up some of the build up of contaminants that can cause injectors to stay open and/or function poorly.The symptoms you describe are also consistant with a failure of the air flow meter.i think they cost about $89 exchange but check the fuel system first as its free to check yourself and will eliminate one more possibility.good luck
