maybe2fast Posted March 12, 2005 Report Share Posted March 12, 2005 So my buddies car (my old one) would crank no start, we checked spark and we had spark. We then proceeded to start cranking and banging on the fuel tank. What bothers me is it finally started while we were banging on the fuel tank. When we got it started or when it decided to start running it was doing some weird things. The check engine light was blinking (OBD1 doesn't have a blinking code like OBD2) the low coolant light was flashing the car runs very poorly and the speedometer was raising to alittle above 5 mph. I really have no idea what this could be but, I talked to my Dad who is a Master Mechanic and he said from what I said over the phone it sounds electrical. The computer is my guess. The rpms go up and down alot, more than your basic idle relearn. my friend said it was really acting up when we were driving it and it was turning 3500 rpm. Any help would be great guys thanks Don Quote Link to comment Share on other sites More sharing options...
GP1138 Posted March 12, 2005 Report Share Posted March 12, 2005 Sounds to me like it could either be the ECM, the cluster/ground, or perhaps your car was misfiring, which is what the SES light blinking indicates. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 12, 2005 Report Share Posted March 12, 2005 i'd vote the pcm myself, and then go from there. i don't see any reason why the SES light and coolant light should flash. Quote Link to comment Share on other sites More sharing options...
maybe2fast Posted March 12, 2005 Author Report Share Posted March 12, 2005 Computer is my guess, OBD1 will not blink even if the car is misfiring, it does not have the capability to detect misfiring. OBD2 will blink if it is missing. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted March 12, 2005 Report Share Posted March 12, 2005 i'd say so. i see no reason at all for it to do it under any normal op circumstances. Quote Link to comment Share on other sites More sharing options...

Crimson Fury Z Posted March 12, 2005 Report Share Posted March 12, 2005 did this progress from normal to bad? might check the ICM. cause i let that problem go and it ran like it was misfiring like a mofo. Quote Link to comment Share on other sites More sharing options...
1990lumina Posted March 12, 2005 Report Share Posted March 12, 2005 Why would it start when banging on fuel tank...could the fuel pump be working intermittely and causing a constant idle problem?? - Jeff L. Quote Link to comment Share on other sites More sharing options...
Crimson Fury Z Posted March 12, 2005 Report Share Posted March 12, 2005 they were banging on the tank. Quote Link to comment Share on other sites More sharing options...
