I was driving home from work, was about 5 minutes from my house..the check engine light started coming on and going off and my car started to die. This happened twice in short intervals, drove about another 50 feet and it did it again, but pretty bad, so I pulled over and shut it down. Before I shut it down I noticed the volt guage was low, I thought maybe i snapped a belt and the alt. was dead. Pop the hood, belts fine. Go to start the car and it just cranks, cranks fast and my lights and radio worked..so I did not lose any power. When I turned the key on I didn't hear the fuel pump, so I checked the fuse for the fuel pump under the hood and it was fine. Again, car cranks the same, just doesn't kick and no fuel pump priming...is it safe to say its the fuel pump? or could it possibly be the ECM or something? My only reason for thinking ECM is becauase I read its the ECM that actually does the 2 seconds of priming the pump when you turn the key. So if it is the pump, do I go and replaace it AC delco OE pump, or do I step it up? Some people have said go 255 and others said it will mess up the stock regulator. In the future I will be doing good upgrades, but little by little and in the future. What do you guys think?
