Truck showed up with a dead pedal and p2122 and p2121 codes to boot. Bought a sensor,replaced it,set the thing to the proper voltage and away I went for a test drive.....it's fixed,or is it
Mofo comes back and it's owner says it's still doing it.....BS ain't no way. Whip out the ol snap on scanner and I come back with a p0148 and a p0088.
p0088 pressure rail -pressure high. p0148 fuel delivery ...
So I take it down the road monitoring the data and when crowding it you can watch the fuel rail set psi and what the psi sensor is actually seeing is the same then all of a sudden the actual psi just falls out to like 2200psi when it should be like 21k.
So ol Ellis says to himself" this thing is running out of fuel" and throws an O'Reilly supply pump in it. We'll guess what that does......makes it twice as bad. It'll actually kill itself and will be a bear to crank back.
I know it's a really bad replacement part now but now I'm doubting myself.
Those that have fooled with them does this seem like the right path?
