1997 Turbo PSD Remanufactured IDM

New to the Forum.... Who do you guys recommend for 1997 Turbo PSD IDM re-manufacturer service? Also, shouldn't they all be asking for VIN to make sure that the reman is flashed properly to my truck???? Reading online a lot of reviews and BBB complaints and it looks like a crap shoot....

Welcome!

The Powertrain Control Module (PCM, box on the driver's side firewall down low) is the unit that gets flashed with the program for your truck. The Injector Driver Module (IDM, silver box below the driver's hood hinge) supplies the high voltage DC to fire the injectors when commanded by the PCM. Any IDM for a 1994-2003 7.3L Powerstroke will work for you. Personally, I purchased (years ago) some used IDMs off ebay for $50 each to keep in the tool box as spares. Cheers!

Thank you both of your for your quick response. I still look forward to hearing comments from other PSD owners regarding their opinion of same.

I am currently talking to Diesel Technology of Chattanooga and Swamps regarding testing of my IDM and/or ECM before purchasing anything. Below is a little history of the symptoms I am experiencing.

I have a stock 1997 F-350 Super Cab, 7.3L Turbo PSD w/ 210K miles. It was giving symptoms of bad CPS over the past 9 months. I replaced the first myself about 9 months ago when it threw a code. About a month ago it had same symptoms but no codes. I towed it to a mechanic friend (Perry) who is trying to help me out. He put in the International CPS part. It ran perfect for 25 miles then same thing, dead on road side, wouldn't run except like a bucking bronco with no power. I had a Ford CPS in the glove box so I crawled under and installed it. Same story...., Towed it back to Perry. It has two codes for bad injectors. But Perry now thinks that it is the IDM and wants to test it before buying a new one or replacing injectors.

P.S. A friend in New Orleans says bolt torque for CPS is around 8 inches (not more than finger tight.) He thinks we are just tightening the CPS bolt too tight and reducing the air gap too much. Specs I've seen suggest 18ft/Should I put it back in and retest CPS with shims and less torque? Your thoughts....

Way back in the day the CPS air gap was more of a big deal and they had shim kits for that purpose. Eventually the CPS became "shimless" meaning the shimming was not necessary. It is a different story if the CPS face is being wiped by the cam (cam thrust surface problems). Snug is good. If you haven't already, I would perform the wiring checks of the article in this link: Ľ TB 103: 1994-03 Ford 7.3L IDM Replacement & Diagnostics
Cheers!

Thanks for your input. I will pass along to my mechanic friend who is helping with diagnosis. Hopefully he has already tried these tests.
