usually the problem is a bad check valve which is part of the fuel pump assembly. Replacing the existing pump with the 255 unit will probably solve your problem.
Also, I dont know what kind of car this is, but L-bodies can have their pumps replaced with out dropping the tank. Just get the tank close to empty, take off the passenger rear wheel, jack the car up on the pass side, and pull the pump out with the tank in place. clay ----- Original Message ----- From: "Tyler" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Sunday, June 12, 2005 9:58 PM Subject: SD> No fuel pressure when key off > My 1985 T1 log car has been having more and more trouble getting > started.
