died and will not start

[c11296]

I am new to this , any help would be great. My 2001 f250 7.3 started running rough, then check engine then quit(all inabout 30 sec) did get it restarted to linp 3 blocks to home. Took it to a very small shop, the tech says I may need a IDM and the harness to the injectors looks burndt also, Then he really scared me when he estimated the cost. Can any one tell me where the idm is, and how hard to change? Also, from ready other post, is this a normal problem? I have 85,000 miles on it. I found an IDM on ebay for 394 with 1 year warranty, any hought on that? thanks.

whao there cowboy, before you go spending big money, change out your cps
(camshaft position sensor) it is located on the front left side of the engine between the water pump and harmonic balancer. It should have a little metal tab brass in color, but yours is most likely dirty. Either way all it takes is unplug wiring plug going to this sensor and a 10mm socket, takes about 10 minutes to swap this sensor out. The sensor is common to go bad and when it does the result will be exactly what your truck did. Starts running rough, then dies, then hard to start back up and may run correctly or may run rough. The sensor is about 110 dollars from a ford dealership. You can find them on ebay for anywhere from 40 bucks to 60 bucks. You can also get one from an INternational dealer as well. Before you go buying parts I would suggest swapping out the CPS. But then again some one else may have other ideas.

Thanks, this is my first diesiel. Kind of deflating when it quit. The tech said the codes were pointing to the ikm, I will try the cps first, thnaks.

I just think that 110 is easier on the pocket then 394+ to fix it. If it was me I rather spend 110 to see if it fixes the problem rather then alot of money.

i would highly doubt that the idm is bad...but this could be burnt harnesses as the tech implied. Just cause the code is for "idm faults found" doesnt mean anything about the idm being bad. That means it has faults with the injectors....and could be a burnt or disconnected under valve cover harness

well, $830 plus 100 for tow later, it was the idm. Found a used one for 300, the tech charged me for install and troubleshooting. Found water in conector to idm. Did have him check out glow plug system and all harness when under valve covers. installed "wedge" kit on harness conections to make sure no future trouble there. thanks to all that sent comments
