RV Totally Stranded For 25 Hours...What Happened?? (My 96 Newell Coach Broke Down!)

What happens here

Recognizing that the fuel pump replacement didn't solve the problem, the RV owner prepares for a more in-depth electrical diagnosis. To allow better access to the engine's top side and electrical components, he removes a carpeted panel and a wooden access cover from the interior floor of the RV, directly above the engine. A second, specialized mechanic (Jeremy from JG Diesel Solutions) arrives and uses a multimeter to systematically test the electrical system. He quickly determines that the Engine Control Module (ECM) is not receiving its necessary 12 volts of power, pinpointing the true electrical fault.

Goal: Identify the root cause of the electrical no-start condition.

they going i've never tried to take this apart before but i know that this is an engine access i'm just going to start pulling on things and see what happens so there's staples in there that's nice alrighty so that's not really supposed to be removed easily yeah this is like a weapon of mass destruction right here oh daylight will you be able to reach it from in here uh if we can reach it you'll be able to reach it right here oh yeah i'm looking right at your hand yeah this is gonna be meant yeah all right let me get the rest of this cover off all right well it's like several hours later uh the last guy changed the fuel pump kept spraying anything in there nothing was happening he's like man it's like i hate to keep throwing stuff at this when i don't really know what it's doing it'd be like 6.85 to tow back to our shop and even then nobody's gonna be able to work on the weekend and i'm like yeah bro leave me here i'll call somebody else so i put out a post on facebook and like a bazillion people messaged me this guy did he said if i can't fix it i don't charge anything so i'm like all right dude just come on out and he's actually like opening the connectors and stuff to like diagnose the issue properly what's it doing i'm pretty sure that uh we don't have a 12 volts with amperage yeah open search there so man i'm just going to run a temporary power wire that'll act as our ignition and we'll just see if we can get this that way so he said he's not getting any voltage at the ecm and he's going to run a wire 12 volt wire to that port just to see to get power to the ecm and see if it fires up and if it does then that was the problem this entire time it's not getting power for some reason which means uh i got knocked for 700 bucks for no reason over that fuel pump which my other feel was probably fine so that is not cool i'm not sure what to do about that so he
