Crank but no start-locked out Mustang 3300V

[Heathenmojo]

Mustang 3300V Yammar motor cranks but will not start, best I can tell, brand new fuel solenoid replaced by previous mechanic whom failed to get the machine back out on the job is not releasing. Machine will roar to life if I spray intake with ether so electrical circuit is open and operating, just no fuel what so ever reaching the engine, fuel pump runs endlessly if key is left in run/on position. I have checked all fuses, repaired numerous faulty switches such as seat and lap bar, and shorted wiring, door switch bypass was also faulty and I repaired the torn wire. with capacitor on it, though according to indicator. panel located in lower cab wall panel, under lap bar switch, perhaps the capacitors are fried or my soldering job was under par, but I believe the machine starts even if door is open, just cannot move anything so I'm ignoring that for the moment, correct me if I'm wrong, I'm at the point though I wish to bypass the control module to determine if the fuel solenoid is or is not working or if the control module is to blame. The timeout relays I'm told could also be something to give close inspection and they did appear to have arc smoke residue PERHAPS on their exterior. Might add the cab overhead digital indicator monitor has some frayed wires (very final photo, purple wire) and currently displays nothing as if not powered, hope to have those wires back together tomorrow but I do not feel. the monitor would cause lock out, again, I know I do not know is the only thing I actually know. Ive located the plug for bypass switch and of course there is no actual switch in this machine, if you can guide me on which wires to gator together (3&4th photo) that would get me major progress I believe, as I'm ready to wager its the fuel solenoid or actual safety module to blame at this point, or at least have a better sense of where to search for faulty wiring.

Hello, how many hrs is on this loader? i assume it is an earlier model that has an ECM, but does not have DPF only EGR.
It would seem as if the ECM has No Power to it, there for it is not turning on the fuel. if i remember correctly they used an injection pump with an electronic governor which would control all fuel flow to injectors, also would be used to shut down engine. if this is the set up. i believe there would be a fuse labeled as ECU. That fuse power would go to a relay. then the relay feeds power to the ECU. i may be able to come up with a wiring diagram

Thanks! It is a 2001 I want to say, but perhaps 2004, and the hrs are high but not absurd. I'll be back at the machine very early morning before sunrise too spend a few more hours on it, I will get more accurate info. You are correct about the ECM., These three components are mounted the left side engine compartment same as the battery

Ok, its going to be a 2011 model or later thats the year they started production.
