Hi, my name is ***** ***** you for your question.
I don't know what Cummins you have but try running a line from inlet of fuel pump (injection pump) directly into a 5 gallon bucket of clean fuel,, (you can use the line on there already that is going to first filter),,hold throttle down and crank engine to start,,a little ether while cranking will help bleed fuel system,, use sparingly,, short burst directly into turbo inlet while already cranking!
If it does not run,,, fuel pump or fuel shutoff solenoid is bad (the 12 volt line you talk about is shutdown solenoid)if it runs you have a bad line,,filter,,or filter head before that point.
You can test each one if it runs by bypassing each line or filter head.
Questions or problems let me know I'm happy to assist.
Thanks spanky

sorry about the delay, I tried it starts briefly (due to wd40 and ether) but will not run, I noticed during the brief time it ran the oil pressure guage stayed on 0 psi and I had no rpms. oil is good. 3 sensors on driver side front of motor 2 next to each other on top of pump 1 rite below that pluged into block all are 3 wire conectors. any suggestions from here I swear I will tip you well for your continued help

First what model Cummins do you have?You ran a test line from pump into fuel bucket?Even if you did not have oil pressure it should start and shutdown after 15 seconds if you had no oil pressure so that is not the issue.Does check engine light come on and go off after you first turn key on?Does the shutdown solenoid have 12 volts with key on and while cranking?while cranking does tach register any RPM?

engine light as well as entire dash comes alive at koeo. @ crank lights as well as dash go off. including engine light. at wire I have 0 volts at koeo and 0.4 volts at crank no rpm is registered at crank also this is a cummins ism 425v

I need to know what model Cummis you have?From the sound of it,, ecm is not being powered up, so you are not getting fuel prime from fuel transfer pump and no voltage to solenoid.Check all your fuses even the ones by batteries.Check all battery connections and fuse holders for corrosion and power on both sides of fuses.

cumins ism 425v / also I am thrown off by the micro voltage to that solenoid? also the dash goes through its self check so I took the ecm issue out of the equastion. I wil recheck the fuses. the symtoms were gradualy lost power on interstate. pulled over lost throttle but still idled then stalled and would not start back up. towed in to our shop I noticed the fuel filter housing (glass bowl on top about 10" long ) was 80% empty with fuel.

You said earlier you had no power to shutdown solenoid and no RPM signal while cranking you said check engine light comes on at key on does it go off before cranking?is (this)your fuel pump? Did you try running out of bucket and check fuel pressure?micro voltage to that solenoid? That's just called ghost voltage it means you have noneI have a doctor app so will be gone in a little bit for a few hourslet me know
