Hey guys, I losgt all power to my just installed walboro fuel pump leaving me stranded on Friday. I checked the relays and its clicking ok and has continuity on the ones the service manual asks you to check for. I swapped with anothe relay (1 of the 4 on the left foot well) and it clicks but again no power to fuel pump.
I checked the resistance of the fuel pump and its measurable so its not a dead short.
Does the ECU control the pump at all? I have the 06 bars wired in parallel with the 07 harness and had them about 3 bars up from bottom, think the ECU is fried?
On a key "on" the relay clicks, it cranks but will not start as the fuel pump doesn't cycle.
Not sure where to go from here?

Blown fuse? Usually when you go to an aftermarket pump if you use the OEM wires to power it you will need a larger fuse.

Definitely blown fuse (the 10A one by the starter relay). I forgot to mention that to you. Put a 20 amp fuse in.

X2 did the same thing. Changed to a 20 no prob. since. Be sure and put a 20 in the spare slot as well just to be safe.

Ok strupid question where is the fuse? The little panel on the side with 6 of them in there? I checked them they were good but I will double check now.

Right beside the starter relay. Used to be attached to the battery holder but it would have been moved with the mpi kit. You will need a long set of needle nose pliers to get to it. If you are looking at the sled from the front it is at the left side of the intercooler.

Dang I found it, I dont think I can reach it with out popping the IC off. What a great spot for a fuse.
Shoot wish I would have done my research I could have not had to ride the backup 500.
Thanks as always for the help. I'll get it out and replace with a 20amp fuse.
