No start cm 870

[Ron1]

Left grand junction Co. For a job 1 week ago. Ran I 70 to Ohio completed job. Dropped off rental excavator, loaded pickup on trailer pushed in clutch started moving and truck just quit.
Truck is demandated. Good tune from running rough. Truck has run amazing for 3 months with no problems what so ever.
It’s a 2006 Pete with 1.4 million in frame suppose to be 200,000 miles ago.
Truck uses little to no oil.
I did have to replace the high pressure pump a few months ago. As it quit about like this coming down a mountain in colorado. Like someone shut the key off.
I have my laptop with me and yesterday after it quit was able to hook up to the ecm. It was dark and my kid was driving me crazy and I was very tired so I just quit.
Came back this morning and insite will not connect to ecm.
1. Some things I noticed. Oil pressure does not come up when cranking.
2. I did replace fuel filters
3. Lift pump is working cycles for 2 mins I have let it cycle 4/5 times.
4. Insite not hooking up today. So I can’t check the cranking pressure from high pressure pump.
5. I have 12.3 volts at computer plug
6. Truck hasn’t been in rain till this happened in Ohio (lol)
7. I don’t have a way to test fuel pressure. Sunday and nothing is open
I did push compu check port fitting and fuel sprayed out on back on pump.
8. Yesterday after it quit I spoke with running rough and was able to hook up to ecm.
It had 3 codes
A lost power to ecm
B. Fuel filter blockage maybe
C. Fuel actuator #2 I believe.
And I thought a turbo one.
I’m leaning towards bad computer but can’t rule out bad high pressure pump as I have no way to diagnose/tell what it’s putting out.

I wouldn’t be so upset other than I’m 1700 miles from home lol on a Sunday.
