as you all know I had a thread in here for wiring, I still haven't got that fixed but just for fun I decided to go out and try to start it, well it started????? I have no Idea what happened. when I turned the key on before the fuel pump would not come on for the 3 seconds to prime the injectors. I have a factory repair manual and have replaced tons of gadgits but from time to time it just dies even at a red light trying to impress some honeys please help :mad:
 
Assuming it's still a fuel problem and not a vacuum leak, some possibles are:
fuel pressure not 47-50psi at rail, leaking FPR, faulty fuel pump or fuel pump relay, leaking fuel filler cap gasket, IAC misadjusted, TB not clean, inside fuel tank either the pickup tube is broken or hoses loose or sump sock clogged, fuel filter clogged, fuel return to tank line clogged or leaking, TPS faulty.
 
Thank you so much I will check these and get back to you. Again thank you. tried all but to no avail nothing fixed my problem. for some reason I can't get the fuel pump to come on when the ignition is in the on position. I checked all of the above....no good...I have replaced the fuel pump relay the pcm I have checked the ignition switch circit the fuel pump relay circit everything checks out good the fuel pump was replaced also. When you jump the circuts on the fuel pump relay the pump purrs like a kitten but not in the on position. does anybody have any other sugestions before I paint it yellow. please HELP
