Thanks, I talked to dealership, they can get the pigtails for various connections, and said I need to follow the wiring to find sticker of harness part number which they can't get,

 

so two recommendations to follow it and see where it goes? where’d it go?

 

i need recheck the 14v it may be 12v
my scan has the power steering pressure switch showing too high, number seems to be frozen. is the switch outside the pump?
I looked under it today, but just in the beam look like there is a pile or something in there. probably from squirrels or maybe a bird.
i will look tomorrow to see where it goes

 

The PSPS power steering pressure switch is on the pressure line
Good luck with this
Dorman modules fail
Ford screwed us on this too by discontinuing the Motorcraft part

 

Ford stopped making the fpdm? Feeling better about having my spare taken out of a crown Vic. If you can find one of those at a junkyard they are in good shape because they were mounted inside the truck.

 

I think so

 

today sprayed out FPDM plug with electronic cleaner, noticed ground wire above, it was corroded and rusted, cleaned it up. code came back.
followed big hose to charcoal canister and little hose to axle/differential
tomorrow going to paint bare metal around ground, and check big plug connection under driver door, for corrosion and rust, spray female end with electronic cleaner
no part number sticker on wire harness

 

"the psi drops really fast, when i turn off the key"
This is generally caused by a leaking injector.


"If the FPDM outputs a 75% duty cycle, it means that the FPDM has detected an open or short on the fuel pump control circuit. The PCM sets a P1237 DTC."
I would guesstimate that 20% of Dorman FPDM fail right out of the box.

 

thanks, is there a way to pinpoint which injector is leaking, can't see anything on scan tool

 

pull fuel rail, turn key on to prime fuel pump.

(id probably have a set of orings on hand to re ring before replacing )
