Class C RV with 1984 Ford E-350 460 Engine Chassis.

We finally got the fuel issue fixed yay! Now we have no spark though and seriously have no clue what could be wrong anymore...

New parts are: ICM, Voltage Regulator, Starter, Starter Solenoid, Coil, and Distributor.

The only way we get spark with the good old screwdriver test is when we attach the screwdriver to the high resistance wire that plugs in to the coil (which we have since learned we shouldn't do?). With it disconnected from the distributor (screwdriver in it's place) but connected to the coil we get a yellow/orange spark right as we STOP cranking. It does crank like a champ!

We have traced the wires to the coil and those are good, we will trace out the rest today and report back but aside from a wiring problem is there anything else any of you can think of? We took apart the harness and the wires LOOK good but we know that doesn't mean they are good. When I say we checked wires I mean that we tested for resistance, is there another test we should be doing?

We're both slightly electrically challenged so any tips help! We're supposed to head out Monday but don't see that happening now

Thanks again!
