4x4 Tbi 350
Okay so about a week ago I had my M.A.P sensor go bad. Well I didn't know it and I replaced my fuel pump fuel & filter.
After I got my problem fixed with the sensor all was good.
Well 2 days ago I was driving and the truck just died. It turns over fine. But I immediately noticed my fuel pump wasn't turning on. so I replaced the relay. The fuse was good. Still the fuel pump wasn't kicking in. So I got out my meter. The fuse gets 12 volts. When you first turn the key to the ON position. The fuse relay is getting 12 volts also. But when I go to the plug on the fuel pump (4 pin) there are 2 black wires. One ground the other I'm Not sure, a white, and a red.
The black and red get no power to them ever. When the key is first turned on. Or after its on. The white wire(middle wire) gets 8.49 volts constant. But I assume that's the gas gauge wire, since my gauge still works.
Any advice will be greatly appreciated!
