Yeah a LPFP DRIVE UNIT. What is that.......
My SHO . I stopped at a WAWA. Shut her down. Went to restart a few minutes later. She started but stumbled and she would not rev. She would Just idle. Eventually died and would only crank. Had her towed her home. Did research for Fuel pump fuses and relays. Not much comes up. Just the relay in the engine comp fuse box.
Code P0087 no fuel pressure and P1145 ? I forget the second one. So no fuel and it was idling. I figured the Rail just ran out of fuel and it was the LPFP somehow but they usually dont just Fail hard.
Did a Youtube search found a video from some guy on the Taurus having a Drive unit replaced. So I used a Google search with a BETTER term for what might be the problem.
Found Bamsho had replaced his LPFP AND His drive unit just to be sure he got everything.
Went to FORD. Got the Drive Unit. $65. Its a 5 minute job. Its behind the Right Rear Fold down seat back. Under the carpet.
BAM. The SHO started right up. Thanks @Bamsho
I went back. Bought the other one they had in stock. It is gonna stay in the SHO now.
LPFP is Low Pressure Fuel Pump, it's the one in the fuel tank I believe, it' supply fuel to high pressure fuel pump that is on the engine.
Check fuse just in case
FPDM = LPFP
FPCM = Fuel Pump Control Module

Yeah if you dont have the correct terms searching you dont find what you are looking for.
It was an easy fix and hopefully this thread will help someone in the future.
