HELP horse482 01-05-2008, 06:35 PM Welcome to the forum. Do you have power to the fuel pump. It is not uncomon for fuel pump relays to go out. If you have power to the pump, make sure that you have a good ground at the pump also. To start turn your key on (don't try to start it) and listen for the pump to hum, if the pump hums then you are getting power and you may want to look at fuel pressure problem. sechracer 01-06-2008, 10:47 PM You probably need 60 or 65+ psi to start, and 55+ psi to run. The pump may run, but just be weak enough to not generate that. vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
