Sounds normal.

I imagine it usually goes off after the fuel pump stops?

Other things too like the CPS starts putting out a signal when the engine starts rotating..other sensors as well.

According to the instruction manual, it should light up for about 5 seconds when the ignition is on, then go out?

Hi, have a 2022 cforce 450.
When I turn the key the EFI light stays on but goes off when I start the engine.
If i turn off it stays off until i turn the key again.
Where should I start troubleshooting?
