02 GT Trouble Starting
I have an 02 GPGT w/ 89,000 miles. Lately it has been trouble starting once in a while. It will start, run for 2 to 3 seconds bog down to about 200 rms then die. After that i need to crank it over for about 2 seconds for it to fire up , and it will idly roughly and i have to floor it for a little bit then it is fine. This happens maybe every couple days. I have alreay checked for leaking gaskets and my compression is fine. I dont have any mods except for the SLP cold air induction airbox w/ ram air inlet. Any ideas????

Re: 02 GT Trouble Starting
Basics fuel or ignition. Check fuel pressure at the fuel injector rail Schrader valve - 48 - 55 psi. Possibility fuel filter, fuel pump, fuel pressure regulator.
For ignition check spark at any spark plug. Based on the symptom it could be a defectve crank position sensor.
