I purchased an e90m3 from a shop I won’t name yet in LA and have been having a series of issues.

The car is totally gutted with a cartek GT isolator.

Most recently I was at Willow Springs coming through 8/9 full clip when the engine completely died. Power on my AIM DASH and the oem cluster was still on - but zero engine power.

I rolled into the pit, hit the kill switcand turned the car off. Waited about 10secs, turned the kill switch back on. All the lights in my AIM and oem cluster came back on but when I pushed the start button I got nothing. No click, no crank, just infuriating silence. This was my 4th session of the day with no issues any other sessions.

On the oem cluster I have the following new warnings:
  • Service engine soon
  • Exclamation in gear
  • Exclamation in (O)

I bought a Foxwell scanner to pull codes and that will be here tonight, but looking for a sequence of simple things to check like:
  • Ground straps (which ones and where)
  • Power cables (which ones and where)
  • Battery check (currently on a antigravity)
  • Relays
  • Anything else?

I did recently move my oem gauge cluster to up underneath the dash but left it fully connected.

I understand pulling codes is helpful which I am doing - so please don’t respond with “pull the codes”. I’m looking for the simple troubleshooting “no duh” things to check first.
