Here we go again, car cranks but won't start.
I know it's a common issue, but I'll go through the basics anyways.
2000 Alero GLS 3.4L
The car will crank but won't start on it's own. If you give it a little gas it will start but will die when you take your foot off the gas.
I suspected the ignition switch\key. Replaced both and had the same issue. Did a security re-learn, NO security lights.
I checked the codes and found no codes related to the car starting. ( just a code for the oil pressure sensor, that I need to replace.)
I cleared the codes and tried to start the car again and it started, repeatedly with no issues.
Waited a few days and it started every time.
Today I tried putting the original key cylinder back in, and it wouldn't start and has the security light on solid. Tried the relearn and the security light won't go out.
Tried the replacement key cylinder again, no security light. And it still won't start.
Tried the original key again and let the car crank for 10-15 sec and it finally started. With the security light on solid. I'm able to restart the car with the security light on solid.
Checked the fuel pressure and it's at 49lbs. (should be between 50-60lbs I believe)
I suspect it's a failing\weak fuel pump, the battery was just replaced a couple months ago and the fuel pump has never been replaced, I'd know I'm the original owner. I'm really close to just disabling the passlock system.
Anybody have any other ideas?
