- FI Fault Type 2 (as shown by flashing "FI" on the LCD). If this is the case DO NOT ATTEMPT TO START THE ENGINE. This is typically a failed injector (expensive).
- Low oil level (well, pressure). Don't attempt to start until you've resolved this.

In all cases, usually the red light (Oil/FI) will be on, so that's pretty useless.
