The Saga Continues - My Wife's Discovery, No Start, Continued Diagnosis
You might want to double check the RAVE but CPS only stops spark and not the fuel pump. The fuel pump should work under any conditions as long as the key is in position II.
Your issue does sound like an electrical problem. Have you printed of the starter/ ignition circuit diagrams and chased the paths?

I just want to pick your brain on a couple things. Happy to trade for that!

It should kill both. Not as a protection mechanism, but because there's no RPM signal to tell the motor when to trigger both.

Did you sign up for the intermediate or advance trail? Every free day I've had from the last couple weeks has been dedicated to getting the rig ready. Made a lot of progress, but not going to get everything done.

Well I'd be more than happy! Looking forward to meeting you, as well as whoever else is there. I'll have a couple cold ones ready for you at the very least.

Was that an option?! I assumed they were at the same time.... Jealous of that Moab trip. That's the next place on our bucket list after we visited the Rockies a few months ago.

Also wrong. The crank sensor is the only input the ecu uses to determine the engine is rotating. No engine rpm = no fuel or spark. (how would it know when/how much to spark or inject if it can't determine tdc/rpm?)

If it runs on spray, it's 98% bad fuel pump. Even if you jump the relay, it doesn't mean you have pressure, or that the pump is even turning. No spark is crank sensor. If you haven't replaced it, replace it.

Still intend to try the crank sensor though, even though I've changed it once. Only other real option is digging into the harness.
