ok ive checked through quit a few things and found nothing, ive takin the the tank back out to check throught the wires at the tank, im not getting any power back there i check with my meter, i even checked the pump and its working, went back through the buses under the carpet every thing looke ok. So i think im ganna run some wire and wire it up like the pumps on my race car with a relay and every thing im ganna leave everything pluged in im just ganna use the black and gray wire that go to the pump. Does anyone see a problem with this?

would love to see an answer for this one, having the same problem now as well except it doesnt cut out like yours (knock on wood). BTW to get to the fuel pump do pull off the rear seats to get to it, or do you need to pull off the gas tank?
thanks

i dropped the tank, My pump is not getting power to it so i plan on getting power to it lol, only thing it will do diffrent that i can see is it will run allthe time when the key is on instead of 2sec but once you start the car it runs all the time anyway. If i could find the control wire off of the cumputer that controls the pump i could use it for my source to the new relay and it might go off after 2sec idk.

oh i see... damn
sounds like a heat issue to me, iv been trying to figure this one out since i got this car but still no go. I was always thinking it was my fuel pump over heating and then cutting out once it gets hot, but now that you mentioned you got a new pump and still the same crap im stunned....
My pump becomes really week once she sits for a good 10min hot, cant start her for ****, and if i do she bucks for few seconds before runinng normal.

what im going to try one hot day is drive her for a while till she gets hot then let her sit for 10-15 min, then im gonna get my sis to start her while i tap on the relay to see it that which is causing the issue. That what my buddy is doing now on his 94 Lincoln Townscar
