Electrical nightmare

[Dentside don]

Went off road in my 19 trail boss and a large branch hit my fuel tank I think and about 3 minutes later it died and so now I have a no crank issue… my bi directional scanner says ignition voltage high , can the fuel pump and or pump module be the issue?? Any help would be greatly appreciated thanks

Since a large branch hit underneath near the fuel tank, I would be thinking more about damaged wiring than the fuel pump or the module itself.
Even if the fuel pump or its wiring were damaged, the engine should still crank—it just wouldn't start. A no-crank condition as you mentioned points elsewhere. Since the branch struck underneath, I would look along the frame rail near the fuel tank for torn wiring harnesses, crushed connectors, or pulled-out ground wires and also look farther forward to see if anything was knocked loose. I would think your scanner should give you an actual DTC so if you have that, it should at least help you narrow it down somewhat. But, it does look as though you ripped out a connector or whatnot, so I would trace wiring from your fuel tank/fuel pump control module wiring and harnesses and move toward the front of truck.

I have looked hi and low forward and back nothing is broken.. when I started it that morning it died after about 2 minutes of running… and it was hard to start back but it did start… so I suspect the pump was on its way out.. this truck is push button start to.

Your scanner does not show any DTCs??

my fuel pump module acted up a few times before ever throwing a code.

the engine would lay over, then ran back up to the setting of the cruise control...it wasnt until the 3rd or 4th time of doing it, that is was sever enough throw any type of code.

i have since read up on some years, the module would fail or start to fail due to a faulty fuse box not proving enough voltage

Interesting never threw a code.

it took a very long cycle for it to happen....it was a full loss of power or solid 6-8 secs, then would ramp up the pre-set cruise speed. when doing 75 ish, you decel very quickly...and then a loud thump that loads the drivetrain and ramps back to speed. the 3rd or 4th event, was long enough it must have signaled a voltage drop.

Yes it shows 6 codes , ignition high voltage, fuel pump control module hi voltage, fuel pump high voltage .. don’t remember the other codes

i have seen a few cases, get diagnosed...repaired (?) and the issues arise shortly after.
we chased similar issues on a 2017, only to find out the FUSE BOX bank itself was faulty. that has been a few years back, so i dont recall all what we did, but it has had zero issues since replacing that bank.

I have checked the run crank position on the fuse box and im showing 2 power but 1 is about 2 volts lower than the other.

That’s the fuse box circuit board.. metal flakes all over. Smells burnt to me

Upon further investigation I am about 99.9 % certain my truck was struck by lightning.. should have a new fuse box this week.. fingers crossed!! I’d like to thank everyone for their help, you guys are awesome

no physical body damage ?

 

[Dentside don]

. other than the hail damage ?? I have not really looked.. I don’t think it took a direct hit.
