HELP no power to Fuel Pump car wont start

I have taken everything apart tested both stock and 255lb walbro they both work. I also checked and replaced the fuse under the hood with no luck where do i go from here i also have no power at the connection that plugs into the fuel pump housing?

I had a similar problem with my car.

If you check all your fuses and they're good, here is the route the power goes

The relay location (2 of ther 3 relays) are for an 04 though

let us know what it was

Good luck

No chance you might have flashed the ecu did you? The immobilizer will stop the pump

No, if you havent flashed it immediatly prior to the "no fuel" issue, then scratch that. It was a mistake I made accidently awhile back.

Sorry, wish I could help more. But I did have a friend with that problem and it was the fuse posted above.
How many times has your ecu been disconnected? I hear after many times of pulling the harness pins can go bad and give you problems. Just a guess.

Power wont get to fuel pump unless engine is started via ecu and FP relay 2/3. I would jumper socket 2 to 1 with the relay 3 removed and do the same to 1 to 4 of relay 2, and then turn IGN to on. To see if you have 13vdc to pin 5 of pump, and go from there.

Possibilities:

1) Fuse (two I think play a role)
2) ECU
3) FP Relay 1
4) FP Relay 2
5) FP Relay 3
6) Wirining/bad contacts

Ok guys i GOT it!! Narrowed it down and this is the anwser CAM POSITION SENSOR best 45-65 bucks spent depending on where you get it. Its the sensor plugged into the head that is right in front of where the stock divertor is i guess i bumped it and cracked it a little and this is what happened due to it.... The car is perfect now thats its replaced.
