| 6-17-11 91 camaro in storage; after starting 3.1 engine it seemed to be running ok but after 3 or 4 min. it stalled and now wont run. Put fuel guage on rail turned over and watched guage rise to 39psi.Had ignition mod checked and its ok. Please advise, Thank you. Jeff |
| 39 psi of fuel pressure is a bit on the low side for your Camaro, but it still should run with that. If it sat for a long time, you could have some bad gasoline in the tank. Possibly a clogged fuel filter as well. If the battery was disconnected, you will need to relearn the idle speed, which takes a while of running if you don't have a scanner that is capable of doing the task. If you can get the RPM's up enough to keep it running, keep it that way for a few minutes, or take it for a short drive. That may help clear it out. |
| 6-25-11 While driving I started losing acceleration. And car engine shut down. Power was still on. Have a new battery, spark plugs. Need assistance. Grand Am 03. |
| 6-27-11 Probably a bad fuel pump. Check for fuel pressure and/or power and ground at the fuel pump. If that's good, check crank and cam sensors, ignition module. |
| 8-15-11 sometimes car starts right other times it starts and dips to low RPM's and i must step on the gas a little bit to keep it running. 99 olds alero |
