Bad new IDM?

Tims02ford · Dec 13, 2014

Tryed 4 different new ones

Arisley · Dec 13, 2014

When you clear the codes does it come right back?

Tim @ P.I.S. · Dec 13, 2014

Please explain "new" to us. I have heard this before and many people us the term "new" when it is new to them.

I have personally installed remaned idm's that were DOA.

You probably have a bad uvch or injector (solenoid). Parts can be brand new and still be bad... what brand uvch/injectors? I would bust out a volt/ohm meter and check the uvch's and injector solenoids

Tims02ford · Dec 15, 2014

Had this going on be for I did rosewood injectors and ford ucch and valve cover and ford engine harness

Check the pins and sockets on the IDM, PCM and 42 pin connector. I would also check them on both sides of the valve cover gaskets.

did you swap the solenoid from #5 to see if the code changes?

im going to pull a ecu out of a truck that i know runs good that a buddy has with the same ecu and try it but the pins on the idm side look good.

i have not but i had this going on on the same cly be for i put the new injectors.
it would be very goofy if i have a a bad injector in the same hole.

mandkole · Dec 15, 2014

Ok, have to keep checking the harness

Tims02ford · Dec 16, 2014

What about the ecu? Or pcm

mandkole · Dec 17, 2014

PCM only tells the IDM to turn on... the IDM does the rest of the work to distribute power to the injectors. If the wiring is fine and youre confident in the injectors being fine, its back to the IDM.
