GT fuel issues

[jjorgensen52]

GT has been doing this for months now, and I'm stumped. Some days won't start, period. Others it will. Today it started, ran about 2 mins, stalled and would not restart. No injector pulse when it won't start. Good injector, new fuel pump, good relay. Anyone know what could cause this?

No pulsator anymore, removed it when I swapped the pump. I have 60 - 62psi FP at the rail if I jumper the pump, and I can hear the pump run when I turn the key

Yep, has spark. Shot of carb cleaner and it fires every time

Re: GT fuel issues

Thanks Dave, that solved the problem. As it turned out, in R&Ring the intake I had bent the contact on the connector in such a way that they were only making intermittent contact. Straightened those out, put in some lithium grease and she fired right up. That's when I found the timing was retarded 18* ... amazingly one can reach the distributor bolt on an L35 with a regular box end

Re: GT fuel issues

Glad you got it solved, I was a little slow reading this thread. I had the same issue before.

That pesky dist. bolt...LOL I used to do it by breaking it loose with the boxed end then flipping an open end wrench back and forth until I finally picked up the one bent in 45* to use with ratchet.
