So recently my car developed an issue where the starter turns for a split second and stops, almost as if the battery was dead. It has a recently rebuilt alternator and battery is healthy. It happens a few times and then starts as normal.

But the last time it did that i had 4x4 error and a service light on when i turned on the ignition. Cranked for a split second. The second time it crancked but didn’t start. I saw for a second thet it threw some sort of amber error for a fuel pump.

Once it starts it runs like normal, even at hard acceleration.

I’m leaning towards some electrical issues going on. Any tips where should i start is greatly appreciated.

Get INPA/ISTA/protool, a decent cable, and read fault codes. No sense in guessing. It'll save you time and money in the long run

Did manage to get it fixed, turned out there was no power coming into the ECU. The small power cable from the trunk was rotten at a connection point at the wheel well
