To recap:

Move your stepper out of the heat. Every 4-5000 miles Whip it out (ooh er missus...) - fire some injection cleaner into the port. Let it soak overnight with a 2p coin as a cap to stop evaporation, then give it a squirt of GT85 (silicon free) PTFE/Teflon on the piston (aka plunger).

When you install the motor it will be lumpy or stall for the first 3-4 starts until it zero's to the ECU. Normal. Rinse and repeat.

Fail to do this and next time you want to replace the stepper I suspect you won't get one at any cost. These units suffer from a Triac issue, and not all can be repaired, and Necam don't seem to be making them anymore. My own supply is limited. If there was one Achilles Heal to the Necam system, it is that parts are getting scarce.

WORK IN PROGRESS
