Ok, got the new tipm in today and it didn't change a damn thing!
So, now I'm possibly looking at the cluster maybe?
1) Somebody explain how the anti-theft device works please. If anti-theft is active...will the engine start up and then shut off after a few seconds, or will it not start up at all?
2) does the gauge cluster control the anti-theft device?
3) does the instrument device also control the obd2?
Trying to figure out what controls all of my issues.
So far I have:
---no obd2 (power and ground are there, but no communication).
CEL and ABS lights are on.
--no ABS communication
-- no gear indicator lit up (P,R,N,D)
-- red light flashing
What I DO have:
-- engine will crank up and run very smoothly til it dies after about 3 seconds. It then struggles to start again...I think this is because of it being a fresh rebuild and not having enough rail pressure?
-- ALL of my electronics work...radio, windows, rear window, lights, ac, blower/blend doors, (some gauges work, others not), heated seats, key fob works to lock/unlock.
I'm trying to figure out what this all has in common. I know the tipm can control all of these things, but that's brand new.
I'm thinking now that maybe the cluster is bad and the cluster is controlling the anti-theft shutting the truck off, and also controls or passes through communication to the obd? Possibly why it's also not showing gear indicator?
I've got nothing talking to anything. No engine data, no transmission data, no abs data, and possibly no anti-theft data.
What's the common link? Other than grounding.. trust me, everything is grounded the hell out. I'm even running jumper cables to various engine/frame locations to make sure.
