Hey all,
For the past month my car has had trouble starting. It would crank and crank and crank and finally start. when I turned the ignition on and let it prime, it would start right up. I figured low fuel pressure. One night on my way home, it would not crank at all. I ended up having it towed to a friend's repair shop and he told me my ignitor went bad. I had him replace that. That made it crank right up but it still had a long crank time. On my way home, the car started skipping like it isnt't getting fuel. It does it the most in gear sitting still or when I really punch the gas. I replaced the fuel pump tonight. First drive it worked great. I decided to reset my fuel/air ratio, so I did that. Right after that it started skipping again. I got out and drove it and it has the same symptoms as before. It is a 1994 GT 2.2 non-cali emissions AT tranny. It is completely stock except for a K&N drop in filter. In the past year it has had a water pump, distributor, spark plug wires, ignitor, and now a fuel pump. The plugs themselves are around 2 years old. Quick help would be appreciated as this is my daily driver. Thanks! |

Hello I have the same car only with a manual trans. The only problem I have ever had is the coil goes bad in the distributor and the symptoms can come and go until one day it won't fire. It will turn over but not start. Not sure if that's it but it seems to be the weak link on this model. I have replaced 3 in 9 years....
Good luck... brandon |

Make sure the fuel pump is in properly, if its not then it will cause obvious things like this. Re-seat it and dont 'reset the air/fuel ratio.'

I guess it could be a bad distributor. Its practically new from a reputable auto parts manufacturer, but I guess that doesn't mean anything now days. The fuel pump is installed correctly.

It isn't the distributor. I just put a new one on yesterday. No change. I'm experiencing long start time again and it seems to miss worse when its been running 30 min or so.

Could be a clogged fuel filter, although I would think that would cause more pronounced issues as the fuel flow increases as opposed to causing delayed starting.

I cleaned the intake out tonight. I just replaced the fuel filter like 2 weeks ago before I replaced the fuel pump. It is mainly happening at idle. I'm at a total loss. It isn't throwing any codes or anything. It just wants to die at idle. It seems like the delayed start has gone away. What is consistently happening is that after I drive the car 30 min or so it heats up sufficiently and it starts falling on its face whenever I pull to a stop or slow crawl. It just doesn't want to stay cranked at really low RPMs. In park, it idles at about 900rpms and in gear around 500-700. It did improve after I cleaned the intake and vacuum lines.
