Well my GTP wont stay running longer than a couple seconds now. On friday my car starting acting up, it started misfiring and dieing on me one night and then wouldnt start but started up fine in the morning after jumping it. The car drove fine for the rest of the day but then come night time, the car started acting up and left me stranded again. But again it started right up in the morning and again drove fine the rest of the day till night time... Now it wont stay running even thawed out in a garage...
I tried unplugging the MAF but no luck (LQ4 MAF btw). Fuel pump has 12 volts to it KOEO. I bought a new FPR and when I went to bleed the schrader valve no fuel came out. After replacing the FPR and a cracked vacuum fitting the car did stay running longer, like 10 seconds versus about 2 before. The pump is a brand new racetronix fuel pump, I replaced it myself like a week and a half ago and my car ran great, until friday when it started acting up (P0300 misfire, and HO2 sensor high voltage). The spark plugs are new too.
Any thoughts?? Does this sound like a bad fuel filter? Cause I cant get my old one off..
