fuel problem
i have found the switch on the firewall, it was down so i pulled it thinking that that would solve my problem.it didn't, so i pulled the fuel filter back off, and turned the key and no fuel coming out of the line. the pump has been replaced.next step!i got a noid to test the injectors, should this be my next step?

what year is your truck ? how many tanks ?
have you checked your pressure reg if your truck has one. have you confirmed that your pump is pumping?
if your pump is working and it is electric in the tank then you should have 35 + psi with the key on engine not running.
if you have duals check the switching valve they have been know to jam or just fail

thanks ,
if i pulled the filter off, and turned the key on shouldn't there be fuel coming out of the line from the tank?i tried this[i got a cheap fuel pump,a gallon of gas and a spare battery] took the fuel line off and hooked up to this fuel pump with a line coming out of the gas can.so with this pump i would be pumping straight to the engine. i have tried this and still nothing!
