Hey gang, here's the quick run down...

Truck needed to be cranked twice before we started our trip Friday, ran and towed fine all day.
Sat. morning took two attempts to cold start.
Sat. in Portland after sitting 3-4 hours took at least 4 cranks to start.
Ran about 80 mi. to Chehalis and stopped at restaurant.... lengthly cranking, many times before lit off.
Got to 1,000 trail campground and shut off. Tried immediate restart, once, no start.
will sit until tomorrow and hopefully lite off in the A.M.

Runs fine once started.
WTS light cycles shorter than norm but comes on.
Plenty of oil, 4k old
CPS swapped even tho tach reads, no effect.
Swapped IDM since I had one, no effect.
IPR is less than one year old.
Discon ICP, still no start
Brand new chip installed Thurs - pulled it out at reastaurant yest. no effect.
No CEL.
No black smoke when finally lites off, so its not injecting... whether electrical or lack of HPO. Susp. electrical since chip was recent change. Again, I did pull the chip.
I have electric fuel system and have 60+ psi fuel pressure when cranking.
Cranks strong, especially after 80 on freeway, so don't susp batteries.
EASE scanner is with me but dead.

Will hope that extended cranking will lite off tomorrow...
Any obv. thing I haven't checked?

Thanks! WiFi not accessible from camp, but with check back...!

***Will check level in HPOP reservior and have jumper cables on it when I try tomorrow!

unplug the ICP sensor

check wiring harness to IPR and make sure nut is tight on the back

you really need a scanner

Hey thanks, gregrob!

I tried unplugging the ICP on hot restart and it didn't make a dif last night.
Today I didi check the wiring and with the ignition on, I have 12v at the red wire on the IPR.

Thanks again, I am hoping the thicker cold oil will allow me to lite it off tomorrow morning. I won't need to shut it off until I get home..... seems to run fine once lit!

Will have scanner when I get home!!!!!

I appreciate the input and will report back!

Blessings!

If you get hung up, log onto www.nwforddiesels.com and post for a rescue and there are some locals that will come a running. Heck, i was just up thru chehalis this afternoon. Wish I woulda seen this before I left, I woulda grabbed my AE and thrown it in the bronco.

If you have a volt meter handy, you could measure the voltage on the ICP during cranking. You want better than 1v on the signal wire (while plugged into the ICP). You could have leaking o-rings on the injectors, and the HPOP cant make the pressure at cranking speeds, but is fine once its running.

Thanks Daryl,

Hopefully the cold oil will be thick enough to lite it off in the morning. Won't shut it down until its parked in my shop!

I had the same problem the other week. Broken injector o-ring. I changed ipr. but that didnt help. I was able to use ether if I had to get it running. I just waited for the glow plugs to cycle and gave some time for them to cool off. You could disconnect glow plug controler and not have to worrie about it. I dont say use ether but if your broke it may be worth a try.
