hmm thats weird problem, good fuse, good wiring no power.. but hydra uses just the factory wiring unless he altered anything..
Try checking the panel with the key in on position, see if that light where it says fuel pump turns on.. not sure if you've done that but check your hydra harness

Problem fixed as stated above.
I simple wasnt crank the motor with the pump connect to the plug on the harness.
The pump doesnt get any power till its cranked.....which I thought there should be power with just the key turned to on.....guessed wrong.
Still hasnt started yet.....The hydra injector settings need to be messed with since I went from a 630cc High ind. injector to a RC 1000cc Low ind. injector and my tuner had to leave the country for a family issue but will be back monday.
unless someone out there have a Hydra map for RC 1000's

Well, little issue getting my car up and running with the new motor.
Went to start her up for the first time this past weekend and the fuel pump wouldnt turn on. After testing some things with a volt meter i found that everything in the car get power beside the injectors and the pump.....everything.
Every fuse is fine, EFI relay is good....at least the ones in the engine bay. And I also tested everything with hydra plugged in and as well as testing with only the stock ecu and get the same results with both.
I thought maybe it was the fuel pump shutoff system but I reset it using the owners manual guide and that doesnt seem to be it.
I should add I did switch injectors to 1000cc RC's and switched to a walbro pump during the build and the wiring is 100% correct. Also the pump works cause I hooked it up to a 9v battery and it powers up.
Any advice from anyone?????
I'm at a dead end and cant seem to figure this out.
