Engine Running Rich and Starting Issues
Posted: Wed Dec 29, 2004 1:12 pm
Hey all,
I've got a couple issues. First and foremost is i'm having an issue with starting the car. It usually cranks and turns over right away and then after 10-30 seconds it dies...like its not getting enough fuel. And it becomes almost impossible to start without draining the battery. I used to be able to remedy this by turning on the fuel pump. Fuel pump is new. I'm not sure if i've got a bad fuel pressure regulator or what? It wouldn't make sense for the cold start valve to be bad because it starts...or the thermo time switch either. Suggestions? AAV? I'm a little stumped.
The second is the car is running very rich! Try 11-15MPG rich...not good. The timing is advanced a couple degrees and air flow meter has been adjusted accordingly. I know if the AFM is adjusted incorrectly it can cause a number of problems...including starting. I'm going to check the AFM against Greg's site. Could there be another issue I am having. I am also going to be replacing the O2 sensor today as well...just in case. Any help would be greatly appreciated.
