2001 7.3l engine stalling out

2001 7.3l

Truck has been running great. Just completed a 2 day 2,000 round trip tow the other day. I was headed to SC towing trailer and the truck first acted like it missed a shift at about 65. I stopped to fuel up. I did not notice when I stopped that there was a ton of water draining right down on my drivers side hood/fender right in the seam. The gutter on the roof was broken and a huge flow of water was coming down.

Got back in the truck and it cranked fine. Hit I-75 shouth and about 5 minutes into the ride the truck just cut off. It was as if though I turned off the ignition. All dash lights stayed on. I put it in nuetral and it cranked back up. Ran about another 3-4 minutes and did the same thing. Cranked it again and managed to get off interstate. Pulled under cover and tried some basic items. Removed battery cables, check fuel bowl for water, checked fuses.

Vehicle would not start. Removed the IDM fuse in the engine bay area and the put back in. The truck started. Pulled out to test it and it died about 1 minute into the ride. Would not crank at all. Removed the IDM fuse again and it started. Same thing happened 1 minute later.

Parked the truck and went to a hotel. Read up and symptoms seemed to point to a fried IDM. Had vehcile towed back. Ran scan and no codes came up.

Replaced IDM relay and vehicle did same thing. Ran a minute an died. Replaed IDM module today. Cranked vehicle and it let it idle for about 10 minutes. Turned it off put all my parts back on truck. Started it up and rolled out of garage bay. Locked up and got back in truck. Started to drive away and it died the same way as before.

I had it towed to a Diesel shop tonight and will wait to see what they say.

Any ideas on what I might be looking at? Maybe ECM?

It is possible ecm, but why is the question. I guess if there was a large amount of water getting under the hood, the IDM and the ECM are both on that side on the fender well. Did you check the cannon plug there to make sure there wasn't any moisture trapped in there possibly creating a short? Just a thought....

ok just to ask did you replace the cps at all this sounds like a dying cps to me try the easy stuff first

[d.austin86]

I was thinking that as well but that should be throwing a code if at fault. But good suggestion, sure beats buying ecm and idm!

Definantly sounds like crank postioning sensor agree^^^

CPS........first thing i'd try

[caneintn]

Thanks for the replies.

It may be the CPS. Irony of that is I actually got a recall letter in the mail from Ford this morning.

So if it is that do I have to have it fixed by Ford? Right now the truck is at a local shop here in Chattanooga. I had it towed there last night. They didn't look at it today but planned on getting on it in the morning. I really don't want to have to have it towed over to Ford and eat a tow bill.

[d.austin86]

Yeah Im pretty sure thats the only way you could get the dealer to eat the cost. You can pick up a replacement cps at NAPA for about $35 tho.

Cam Position Sensor.

I am going to leave the IDM on it. $169 with a lifetime warranty.

I bought 2 extra sensors and put them in the glovebox along with socket, extension, and ratchet.

Thanks for all the replies.

so it was the cps that was bad?
