i didnt see new dist. on that list of things, my guess is the pip pickup in the dist. Ive heard its a real bitch to do, so the easiest thing is to get a new dist. (or used that is good)

yes, the one in the intake is for the guage, the one in the cross over pipe is for the ecu..:thmbsup:

yea the sensor in the intake is for the gauge
I had the same problem as you and it was the sensor in the pipe.I actually had the wrong plug on it and switched the plug back and worked fine

I read that this symptom could be caused by an ECT (Engine Coolant Temp) sensor.

A couple other things it could be EEC relay, fuel pump relay. When it won't start does it have spark and or fuel pressure?
