Left Battery connected Pulled grond at trans Motor has a redundet ground from front of engine to shock tower grounding point for jumping car

Never seen that before, I have nothing going to that post. Must be on the newer cars

 

[Unholy707]

You intelligent battery sensor is plugged in?

 

[Unholy707]

Why did you have to put a new alternator on it?

I can't help with this particular prob but I have been working on cars since the '60's and bad grounds caused weird probs even back then. I agree with UH that it is the first thing to check.

Thought maybe it was the alternator as the problem

 

[Unholy707]

Yeah you need to scan the BCM and see if there’s any stored or active codes. Is your car tuned? Anything else done to it?

 

[Chuck]

yes Curt tuned it its no where near stock everything is pretty much changed

 

[Unholy707]

Do you have Alfa obd?

Yes Jon sent me an answer to check continuity of ground cable it checked to be good but I went ahead and replaced it anyway we will see what happens in the morning

While you were installing the new Trans, did you work on anything else or move anything out of the way?

The one at trans to shock tower

No only trans work

I’d start looking at a wiring diagram and see what ground circuits are in that smaller ground cable. So you removed the starter with the battery still connected? Car running or not, there’s power if you didn’t disconnect the ground wire when pulling the transmission. Always pull the negative battery terminal before disconnecting anything. I would get Alfa obd it’s free to use (for a short amount of time), but you need the obdii dongle. My fuel light would blink and I’d get a message (service fuel sensor) but no codes. Scanned with Alfa and it told me there was a BCM code stored for a short to ground on fuel level sensor B, which was great because it told me which floater went bad (the cars have 2). You replaced everything I would have looked at as the first culprits (battery, alternator, ground strap.) you checked your intelligent battery sensor? It’s the connector on the negative battery terminal
