Pull the small wired off of the starter relay and try it. If there's no change, then it's either the starter relay or the starter solenoid. It it doesn't crank the engine, then it probably is the ignition switch...

Why do you have one with two small wires? Should just be the one and the relay goes to the ground.

I think that red booted one is factory, where's the other end of that black booted one go to?

My mistake on the smaller wire on the large lug.

But I am curious still about that black booted red wire on that second terminal. Since the diesels do not have an ignition system they don't have that second terminal.

why are there two wires on the starter side of the relay?
i think that may be your problem. you may be back feeding power to the starter solenoid.

and the fact you just replaced it does not mean anything these days, i have had to replace 4 brand new from the store solenoids in one day just to get one that worked.
after the first one was bad i drove the truck to the store and replaced the other 3 rite there in the parking lot to prove to them it was their parts and not me.

That's originally what I posted too, but then realized the smaller wire is the trigger for the solenoid.

look again. there is a large and small wire on the battery side, two small trigger wires, one on ignition terminal, one on start terminal. then two wires on starter side, a large to starter and another small one. there should not be two wires on the starter side, just the main wire to the starter.

I know, that's what I thought too, but I looked at mine and it has the same wire. Goes from that large lug on the relay to the small terminal on the solenoid on the starter. It triggers the solenoid the same time time it spins up.

The small wire is a Ground for my e-fuel pump thats on the Body ground screw not the stud out of solenoid. I replaced the solenoid and it starts ok. Are there any companies that are make a Quality Soleniod or do you guys keep a spare in the truck all the time ?
