thanks, checking it out now.

Either of you guys have any luck?

Mine got towed in yesterday. Went over everything . I really think it's the pcm but want it scaned before I throw more parts at it. Everyone i ask about their trucks has 2-300000 miles on them with hardly any issues so this is just a fluke. At least with the swamp IDM it will be a little faster when I get it back.

My transmission is a hit and miss, some days it acts up, and others its like nothing is wrong! Did not have the chance to do anything to it this weekend.. never had a single issue till last year, stalling for no reason, then no starts, to the trans problem im currently having! loosing faith in her!

That stalling for no reason and then no start could be the crank position sensor, that is what mine did and if I remember correctly when it would not start you could get it to reset by cycling the ignition key to on, I think you had to do it 5 times. When mine quit there just happened to be a diesel mechanic across the street that told me that and it worked.

Rwbrew3 , your stalling may be the cam positioning sensor ? I have a 7.3 in my work truck with over 500k and still runs great

If your torque converter is f.g up fix it now and maybe you can save your trans. Mine has had minor problem for about 4 months , broken starter wire then the starter after that now a no start issue and the water pump is leaking. The truck has low miles and is clean, the alternative is a 50g new truck, can't do that.

It turned out to be wiring harness problems from the idm to injectors and also replaced the injector harness under the valve covers because the connectors were f..g up and throwing codes. Had them replace the glow plug solenoids at the same time because they seemed to be hotter than normal. The idm was still good but in my throwing parts at it trouble shooting ,it was replaced with a Swamp diesel performance one. you can feel the difference and there is more power. Now a water pump and a couple of rusty power steering lines., and then it will be time for brakes. Thanks for all the responses.

Ok, the high side of the injector voltage is 100v. That is why the harnesses are marked in red tape. Please be careful. Also, the IDM (injector driver module) senses a fault on one injector it will shut off the card in the IDM that controls an entire bank. You could have something odd, like a circuit low on one injector on the lh bank and the UVC harness disconnected on the rh bank. You need 500psi of high pressure oil before the IDM will even think about sending voltage to the injectors. Ck the obvious first, fuel and oil. Ck and make sure you have module prove out. When you turn the key to run the ck engine lamp and glow plug wait to start lamp should illuminate. Also, you should hear that loud "snap" of the glow plug relay closing. The dash lamps and interior lamps will dim due to the large load of the glow plug system.

This may seem odd but i see it lots. Make damn sure that the battery terminals are clean and tight makes sure the pinch bolts move in those old lead terminals. make sure the posts and terminals are clean. also make sure you are starting with two good batteries. During glow plug operation and cranking... If you drop below 8v the modules like PCM and IDM will go to sleep.

Rick is it a transmission problem or in the column ? have seen pinched wires in the steering column when you move the shifter to 1/2/D even seen them pop fuses and truck stalls till a new fuse is installed under the dash . don't lose faith
