Hello, I've been having some issues recently with my e90. After leaving it to sit for a month I couldn't get it to start but replacing the ground strap got it started, however I am experiencing harsh misfires. I have tried moving around the spark plugs and coils and one of the misfires went away, however the others are persistent.

Originally had misfires in cylinders 2, 3, and 6.

Moved spark plug 1 --> 2,
3 -->4, 5 --> 6.

Now just 2 and 3. No misfires on 1, 5, or 6.

Any ideas on how to proceed? From what I've read it could be injectors, or fuel pump. I've been sorting electrical issues so it might be some janky electrical issue .

Codes are as follows:

Fuel Pump Control Module :

• 6295 - EKPS: No Control Current

DME:

• 2775- Air Mass, Plausibility; Air mass too low
• 2EEA - Misfire Cylinder 3: Fuel Injection Deactivation
• 2F01 - Misfire, Cylinder 3: Detected
• 2EE7 - Misfire, Cylinder 2: Fuel Injection deactivation
• 2EE0 - Misfire, several cylinders: Fuel Injection deactivation
• 2F00 - Misfire, Cylinder 2: Detected
• 2EFE - Combustion misfires, several cylinders: Detected
• 2FA9 - Ignition, cylinder 2: Combustion Period too short
• 2FAA - Ignition cylinder 3: Combustion Period too short
