Cat C15 Engine Fault

Here's a clip of my truck while i'm driving on the freeway. I am trying to figure out what is wrong. Does anyone have any experience or any idea of what is happening?

Bad fuel will not make the cel, stop engine light come on ,and the speedo and tach gauges sweep. that is a ecm power fault, It could be the key switch to ecm or all time power/ground to ecm. I know, I have rewired these same trucks, and I work on CATS for a living.

I know what you mean, I dont understand neither, but I had replaced the key switch and rewired the power and ground that goes from the batteries to the ecm before... but honestly

the problem still remains until I run the truck until it almost got empty and refill with fresh diesel.

****Problem Solve****

so after going thru all the mechanics they got in Jersey and spending tons of money on parts that got nothing to do with the problem, I finally found the main reason of the engine fail.....it was bad diesel... I drove my pete until the tanks is almost empty and went to fill up on one of the Sonocos gas station they got on the Jersey Turnpike and the problem never came back again, so I realize that the problem was cause by cheap fuel

@truckertwotimes

 i would say buddy you are bang one with your thought !!! there is a fuse in the ecm harness that will cut power to the main start power that in turn will shut down what i am seeing here , and if this has been rewired mmm ))) i have seen these fuses and relay in main ecm cause much gray hair !!)))

Sounds like super trucker syndrome to me.

550 or 475 hp's?

After spending so much money and time.. and it was only bad fuel. Fuck thats a kick in the teeth aye!

[memopat1]

well is that correct about 47000 going on 48000 hmm warranty is what am thinking next have you had the truck checked with a cat et a true et reader they can hook up and set a recorder to check several different things see what takes a dump hmm will it do it with the cruise control on more when hot or cold or just does it all the time grounds grounds grounds they can make you go crazy

at all rpms and gears ? not info best and always check the little things fittings and fuel pressure

[MrFrank1948]

acted like you turned the ignition off, then turned it back on Seems like a ignition circuit problem

[okDesperado]

It is ignition relay behind left instrument panel. It will give varying problems from intermittent low voltage to complete failure.

Speed sensor on the tranny

Maybe a Arenoid on the fuel pump.
