It's dead again, need help
Just got truck back from being towed after it died. They got it running, said worn connectors on sensors.
New pig tails showed up yesterday.
Truck was running great until last night, started cutting out, bucking, made it home.
Changed ICP pig tail, no start.
Connected torque pro app, hpop builds pressure cranking (like to 3000psi) ipr duty cycle rises with hpop pressure, up to 48%.
I can see rpms while cranking on the app, still swapped in my spare cps.
Truck will occasionally fire, but only sort of stay running if I keep key in start position.
Checked continuity on the brown/white wire between icp and cps, it's not open.
Went to check it on pcm to icp, but no clue what pins are what, have to clean wires up some I suppose.
I am kinda stumped. Didn't check my fuel pressure this time, checked last week it was 55psi.
It's cold, but it's been plugged in and cold temps have never been an issue.
Batteries are on charger, good volts while cranking.
No one wants to work on it, starting to include me.
Has to be wiring someplace, trying to read schematic so I can start checking for resistance/bad wires.
Tired of walking 3 miles to work.
