3.4 no fuel pressure.

I replaced the fuel pump last weekend and Im not getting and fuel pressure at the engine. First of all the PCM wasn't sending a signal to the relay to turn the pump on so I bypassed it to get the pump to work. And theres no pressure up there. The fuel lines are good, no kinks and the filter is new. Any ideas?

3 things
1)either the pump isnt turning on

2) you have a block some where)

3) you forgot to put fuel in the tank when you were done

i would figure out why the pcm isn't telling the pump to kick on. you can try going to a junk yard and getting another pcm exactly the same as yours and give that a shot.

I got the pump to turn on and the tank is full of fuel. I've thought about getting another pcm but its giving the engine spark. I dont know.

i am a little confused, do you have power at the relay? do you have power at the pump? did you forget a connector at the pump?
