runs for about 20 seconds

eticket · #1 (**permalink**) 09-01-2003, 11:51 AM

I need some help here. My 351w runs for about 20-30 seconds than dies, and will not restart for about 5 minutes. Then it will fire and run for again for 20-30 seconds. The car was running fine about 3 weeks ago and it sat for awhile and when I went to fire it up it is running like this. During the 3 weeks span I had replaced the Edlebrock with a demon carb. So far I have rebuilt the demon carb, swapped the demon back with the edlebrock, tried a different coil, and put on a new cap and rotor. I have noticed that when I had a plug at the end of a wire that I was getting good spark until about 20 seconds and the plug was not fireing, but the engine was running a bit but really rough, and then died. I have a ford electronic distributor, I don't know if the ignitor may be bad in the stock ford electronic distributor. If you all think it may be the ignitor, what years were the electronic distributors first put in Fords as it has a small cap, not the large style caps on the 86 and up mustangs. I have a Mallory distributor I want to put in, but I would rather get it running now and then swap out the distributor, instead of playing with to many variables.
I have checked the carb and before and after and right after the engine dies I have gas squirting out the nozzles, and my pressure is 6 psi. Thanks for the help

Hi Mike -

Actually this is Turks section - he is no doubt off on his new Harley so I thought I would chip in and offer a suggestion - at the same time including a miniscule amount of humor...

Pat thanks for manning the tech support. I had to let the other girl go again. Same problem all over. Man it is getting tough to get good help nowadays.
To our beloved customers, if you call on Monday-Fridays between 9-5 PST and we don't answer the phone, there is a good reason.
Let it ring.... WE do.

RSI (Europe) helpdesk here:

Eticket - do you have an electric fuel pump? Is it wired through an oil pressure switch?

If so - check the wiring, could be the switch breaks on rising oil pressure (i.e. as the engine starts), stops fuel pumping - engine stops. Then when you check your fuel pressure with the engine stopped - bingo! it's back.

Believe it or not, I have seen this before - the guy had tried 3 carbs, 2 distributors, several ignition packs, and was about to commit suicide. When I diagnosed it he was so annoyed he never spoke to me again. His loss.
