as I stated you check signal return and vref at the ebp they are shared if at the ebp connecter sig reture and vref pins test as if they are shorted together then I would suspect the icp and connector as fault, when vref and or sig return shorts you well have a nostart or intermit nostart.

I'm not sure if I did it right or not, but here's what happened...
I had the KOEO, tested the EBP for voltage, and got nothing....
HOWEVER, using the datalogging feature on my SCT (KOEC), it showed the ICP putting out atleast 1.00 (sometimes as high as 1.30) while cranking.
As if that wasn't weird enough, I go looking for the ICP sensor according to William_04_X's pics and it doesn't seem to be there...

I see what appears to be the harness that goes to it, but I see no ICP sensor connector.
Correct me if I'm wrong, but is the ICP not within milimeters of the IPR? I.e. if you're able to touch the IPR connector and the IPR itself, you should be able to atleast see or touch the ICP sensor....right?

If the ICP isnt on the driver side, its on the passengers side closest to the front bumper, its hard to miss it. Also alot easier then changing it on the drivers side

Don't know a whole lot but last year my 03 sd 6.0 had pretty much same issue. Only start cold and run like hell when warm. It was giving an injector code when I had it downloaded. Long story short fuel injector was bad not keeping oil pressure to one injector will cause a no start. Appearently oil was thick enough cold to trigger pressure sensor to bad injector.

I'm not one to count my chickens before they hatch, but we've made some good headway and it's looking like it's the ICP sensor...
As soon as we were able to get the sensor off, we found that the sensor had ruptured and was covered in oil. The wiring had also been covered in oil, so we're having to redo that too.
ICP-$150
New Harness- a shocking $95
Should be done with it today, just gotta find out when they're ready...

Replaced the ICP re-did the pigtail, wires were checked by two different people, and STILL NO START!!!!!!
Checked the FICM, good voltage...
Did the oil filter test where you push each plunger down with the key on and the oil filter bowl filled, but filled slowly.
Same with the fuel filter up top, pulled the filter, had someone turn the key on, and it too filled like it should.
Starting to think it's the hpop, but whatelse can I do?!?!?
