1997 Ford Powerstroke diesel IDM Module Problems

Hello, I have a 1997 Ford International 7.3 liter powerstroke diesel. I have been having problems with it so I took it to the shop, and they said it was
the IDM Module. Does anyone know what that is, or where it is located??
I would like to fix it myself if possible, Thanks.

Welcome to the forum, safesidegirl!

The injector driver module provides the high voltage (120V or so) to activate the injectors to inject the fuel when commanded by the truck's computer. It is the silver box just under the driver's side hood hinge. Any IDM from a 7.3L Powerstroke engine will work and replacement is easy. If you have the time to hunt on ebay, you can find them for cheap (at least you used to be able to ... I've got two spares that I paid $50 each for a few years ago). A lot of times the IDM gets blamed for other problems such as burned/melted injector/glowplug wiring harnesses, but they can go bad due to water leakage or burned internal electronics. As Rick mentioned above, are there particular symptoms your truck was exhibiting? Cheers!

I was lucky and took my truck to the local ford dealer and paid $834 yes eight hundred and thirty four dollars american. Plus $300 for diagnosis and instalation. Be sure and not go to ford to purchase an IDM. I took my first and last lession about the local ford dealer. Just for your info if you did not already know.

( Symptoms= Feels like its running on only 2 0r 3 cylinders. Rough riding, feels like It's not going to make it home, not much power.)

Thank you all so much for all the information!! It has been a great help.
I have located the IDM Module and am going to try and fix it now. I'll let you know how it goes. Thanks again!! Have a great day.

Are you getting a check engine light ?..

Before you spend alot on an IDM ,it may be worth having the scanned & a buzz test for codes...

IDM Location

I have an 03 Excursion with a bad IDM. I have been told by several different people, the module is

1 under the hinge on the drivers side
2 I have to remove the wheel well on the drivers side to find it
3 it is attached to a valve cover

I have even removed the battery and air filter assembly to see if it was under it.

Did Ford hide it somewhere special on the Excursion?

Thanks

Thanks, it was behind the wheel well

I was hoping it was in an easier location. I had to remove the running board and the clips for the fender flair to get at the wheel well.
