02 ST Fuel Pressure Issue

[DubbleN]

Working on a 2002 ST. manufacture date 02/02

My original problem was a bad fuel pump.

Pulled assembly replaced the pump only and truck will now start but is not getting proper fuel pressure.I am getting long crank issues due to the low fuel pressure.
It only builds @ 40 psi with key on and rapidly bleeds off.

I have not done a volt drop check.

Can a bad connection in the circuit cause the pump to not provide the proper fuel pressure?

Sounds like you have the wrong pump

part number i received matches the manufacturing date, as there are 2 different parts that split in 02.
I tried calling for specs on it and the "Tech" i talked to never gave me the fuel pressure rating for the pump just told me if its spinning its not the pump i must have an electical issue. i.e bad connection in the circut
