2015 thor hurricane no start

the heading is extremely misleading as the engine will start as long as you jump
starter soliniod ;;So obviously theres power to the system when having the key in the run position;; sounds like there a malfunction in the ignition start relay modules etc

What Dale said is true, we are just shooting the dark here. Thor could have caused the problem, as they do modify the system furnished by Ford. That's why I suggested checking with the dealer first. No one else has chimed in, that has that near a year, so it may not be a common problem.

Have you checked the chassis battery disconnect? If the circuit is open if will act as if the battery is completely dead. I suspect since you were able to jump the starter solenoid and get the engine running the alternator would power the engine but no telling if you'll have correct power distribution for system monitoring or even correct startup sequence for the various powertrain processors which could cause the warning and caution indicators.

A quick check would be the entry steps which are powered from the chassis battery. If they extend or retract then disregard my idea.

Second place to check would be the high current fuse panel and relay panel which is on the engine firewall above the air filter box. There are two, a big one on top is fuses and a smaller one below is relays. A bit of a long short but simple enough to open and inspect.

Third would be to clean the battery terminals and any grounds to the chassis around the engine area. Even if they look OK pull them and hit the terminations and whatever they are attached to with a wire brush or sandpaper. There should also be a grounding wire between the engine block and transmission to the chassis that you should clean also.

Fourth get a good strong flashlight and start looking around for possible rodent damage or anything that doesn't look right such as a loose connector or a wire end just hanging in the air. Pull the engine cover and check the top of the engine.

Might in that gray area of overlap between Ford and Thor. Take the coach to Ford and they find the problem is the disconnect they might hand you a bill since that would not be covered by the Ford warranty. Just be aware of such.

Do you have an emergency road service plan with RV Tech help? I do and I have used that in an emergency. Over the phone help.

Trying to avoid that thought I could get some help here lol I will figure it out

I assume you are still under warranty, take to Ford, ask the dealer about it first to be sure.
