Motorhome is a 1990 and i assume the RV is factory, however a lot of the wiring has been cut. The motor does not turn when the "start" button is pressed, however, it cranks when i jump the solenoid with a screw driver (though doesn't start)

There's two wires from what i'm guessing is a fuel pump (fuel line goes through it) that i have no clue where they're supposed to splice in to.
There's a pretty decent gauge blue wire from what appears to be coming from the couch (i'm assuming this is the main power wire to breaker)
There's two white wires from the harness that are cut, if i test these while cranking, my volt meter reads "overload" while in DC. I get about .040 volts of AC however.

I'm assuming i need to find another wire in to the couch and the two coach wires tie in to the two white wires that are cut. It shouldn't matter if i wire these backwards as it's AC, correct?

Yeah, i know this post is a mess, but so is the wiring on this thing. Any input is appreciated.

There must be a reason for those wires to be cut...... I'd be sure that the 110V line going from the genset to the MH is disconnected before attempting to start the engine.

Once you've isolated the genset, jump the ign wiring with 12V, remove the air cleaner and spray a little starting fluid down the carb while cranking the engine (be sure to have a fire extinguisher at hand). If it starts then dies, there is a fuel problem. If it doesn't start, there could a # of problems but I'd start by pulling the spark plug, putting the plug to ground, crank the motor and be sure that you have spark in the spark plug. If it has spark, move on to doing a compression check.
