Wonder if ecm program differs from push to start to key start?

You wouldnt rhink so. But if that was the case he could just pop the push to start button off and put the key in yeah? Are they still like that? But if hes got power to the starter leverything is working as it should cuz otherwise he wouldnt be getting power down there. So either bad ground. Or the starter just so happened to take a sh@@. Hard to figure things out without being there LOL.

here ya go! looks like a lot of that sends a signal to RF hub, even clutch. I would check to make sure you have power coming out to starter from whatever sends it like a BCM. with the PTS but it be a programmable thing, Ill look into it. it hard to diagnose remotely.

It amazes me that people do these swaps without reflashing the whole truck. I'm at a loss of ideas LOL

So I have gone over everything again and again. I’m starting to think maybe just maybe I have a starter issue??? Even though I’ve never had any issue with it before?

How many miles are in he truck. Can you jump it from the solenoid and get it to turn?

I got a custom program written for the trick that is a complete e flash. Just as if I was to take it to the dealer

I have emailed double r diesel that wrote the tune. Ray informed me that push button and key tricks take he same tune.

If it's got power and ground. And it's getting the signal when you try to start it then its definately a possibility.

If I had to guess it would be because there is multiple modules that talk to the ecm and look for inputs from the auto trans. So in my mind you've got to get all of the modules set up the way a G56 truck would be and not just the pcm. Scanning the truck would uncover that.

Agreed
