Hopefully someone can help me with this problem, I've replaced the ECU, the fuel pump module, checked all connections, all safety switches. I do have 12 volts at the fuel pump module plug but pump won't energize any help would be appreciated and thank you in advance for any help.
Yes I do. Brand new pump, also I have checked for continuity in the pump and that is ok all safety switches are ok all grounds ok. This one has me stumped. Electrical Gremlins are the worse.
you have 3 fuses on the engine, 2 are 10 amp (red) one is for permanent power to ecu, the other is switched power from key switch. you need both for ecu to work and fuel pump to turn on. the switched power goes through the 25 amp regulator fuse (white) at fuse panel by key switch. engine will still crank with one of these fuses blown. my best guess is its the 25 amp fuse, check them out.
What engine does it have I am thinking the kohler look behind the seat where the fans are for the hydros there are some fuses in that area close to engine.
