IDM ?

[scheidt27]

My buddies truck just wont start, it cranks but absolutley nothing happens, no fireing whatsoever. Anyways the place he takes his truck told him it was his IDM and it would be 1400 to fix. Ive looked on ebay and you can get one for 150 used with a 1 yr warranty. Does this sound like an idm problem. It also leaks fuel when you are cranking on it. Truck is stock with 200k on it

Sounds like it could be the IDM. But where is it leaking fuel from?

[scheidt27]

I almost wanna say from the drain tube from the fuel bowl? O-rings maybe bad on drain valve? It was -30 with the wind and my hands were frozen solid so i didnt dig into it as much as i should have. He had it in the same shop a week earlier for the same thing and i think they just put a new fuel filter in and it ran fine for a week or so. It would die sometimes as well, i put my spare CPS in thinking it was maybe that, but that didnt fix it either. Where is the IDM located and how hard are they to put in, looks like you just bolt a harness into it similiar to the PCM?

The IDM is under the the driverside wheel well. Pull the wheel liner out and it will be in there with the ABS module. The IDM looks similar to the PCM.

howard, do you think it is the IDM, going by what i have described?

fuel leak sounds liek the o rings, especially on cold days, if they are older o rings i know they can leak in the cold, when it warms up they tend to stop the leak, but deffinitly worth replacing from what ive learned...idm sounds like it could be the problem as well

[scheidt27]

yea im assuming they are probably the original o-rings. I'll let him know what ive found out for him, thanks guys!!

This might be a little far out there, but I was given the same prognosis. My truck would start though, but it would take a while. It turns out that I am not getting much fuel pressure. Might check into the pump. I tried the new IDM and it didn't work.

[strokin_early_99]

If you want to see if the fuel pump is working good or not, turn the key to on and while the pump is still on, open the fuel drain. See if it dribbles out or squirts out. I highly doubt it is that if it ran before.

Is the fuel gelled? Pull the filter cap and check.

Did you run a glow plug test to see if power is getting to the relay properly?

Have you pulled any codes? If there are any, what are they?

The IDM is not a common item to die. So that is why I am skirting the idea right now.

[scheidt27]

He has it at the shop he always takes his truck to, they diagnosed it as the IDM, thats all i really have to go by. I got one on ebay for 150 bucks with a 1 yr warranty. I cant get ahold of him now to get the codes it threw so im gonna go with it being the IDM. Once i get ahold of him i'll post the codes.
