Ignition

[Yamas]

So another one, out at new year and when ignition turned off engine keeps running, stopped after a few times but now doing it again any ideas please.

Known as Dieseling. Whats the engine.

Could be the fuel cutoff valve, or glowing carbon deposits causing ignition or failing fuel cutoff valve.

When I by-pass the old Fiat immobilisers if you don't fit a manual switch (simplest way) then the old diesel engines will carry on running if you supply it with 12V power. The old immobilisers were just a circuit board between the fuel pump and the 12v supply, hence ignition OFF also turns off the little circuit board and starves the engine of diesel.

I don't know what age of MH you drive but could be a simple loose connection in ignition wiring to the ignition barrel.

possibly solenoid valve on fuel pump not closing transits were known for thisi had one for ages had to stall it to stop
