94 mustang, 347, start and drives fine, then this weekend it stalled out and left me stranded - would start for one second then immediately die.
Given that I've had a bunch of work done to it, dyno tune, chip burned etc I started trying a few things. Unplugging the mass air to see if it would fire, then as a last ditch idea, I pulled the spout connector and it started right up and drove to allow me to get home.
It threw 543 codes + 564 (Fuel Pump Secondary Circuit Failure 543 + Fan Relay564). I replaced the CCRM and the car drove great last night and then this morning on the way to work. No codes after that, other than 511 and 565 KOEO, and 116 KOER.
I went to get lunch, and the thing stalled again on me. I pulled the spout and got back to work. No codes other than the 511, 565, 116 this afternoon either.
Anyone know why this might happen? And why pulling the spout would allow the car to drive again?
I've read everything from bad PIP, BAD TFI, Bad Computer, Bad Ground etc. I have another car I can pull parts from and test, but what do you think is the best step. The last thing I want to try is the distributor, because I'm wary of getting the thing timed right again.
