I am positive, because I have done that myself, I marked the slot with a red sharpie, I even replaced that fuse with a new fuse, and the pump works great. Same relay and pump sounds as before.
I drove my ST into my air conditioned garage, shut it off, and pulled the fuel pump fuse, tried to start truck, to relieve fuel pressure, and it would not start(I assumed that it would start when I put the fuse back in). I replaced filter and hooked my gage to the engine side of the new filter, replaced the fuse and turned key on, pressure went up to about 12 psi, I cranked the engine and the pressure went up to almost 80 psi and held at about 60 psi until I took gage loose, that indicated that the pump was good so I hooked the engine side fuel line up, cycled the ignition on/off 5 times and then tried to start it, would not start, and it has not hit a lick since. Opened buterfly with my hand and sprayed starter fluid behind it and it didn't even try to start, took middle plug of driver bank and grounded against the block and turned off lights, turned engine over, no spark.
L1, will the ECM/ECU throw a code to indicate where the problem is even though it won't start or does it have to be hooked to a Dianostics CPU at the shop. Hoped it was some strange Ford type safty reset.
I have the Ford shop manual but not the diaganostics manual
L1 where would you start?
The build date is 12/04, one owner(157K miles), and no one else has worked on this truck but me (except for tires).
