Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Sudden death of a Plus4

A friends 2010 Plus4 has just suddenly stopped. Engine will turn over, fuel pump primes but engine will not fire. Any ideas what might be wrong. I was wondering if a sensor had gone awol but I've no idea where they are on the Plus4 engine...different to my Sigma!

Does it have an immobiliser?

Hi Its my mog that have died. yes it does have an immobiliser

Try resetting the inertia switch if it has one. I know of another +4 which suddenly died and once the inertia switch had been pressed it returned to normal operation.

I belive that inertia switch in on the fire bulkhead on the passenger side. I have pressed the black rubber button on the top without joy

It is said that if the ariel wire inside the steering column cowl drops away, the key sensor won't be recognised. I believed though that the car wouldn't turn over if this was the case. But the position of the wire inside the cowl is worth checking.

Fuses - mine is 2005 so the position of the boxes may vary, but........
Fuse No7 of 8 under the bonnet is 20A "Engine"
Fuses 1,2 and 3 under the dash (block of 20) are 15A "Engine" fuses.

On this model the fuses are on the bulkhead in engine bay just in front of the driver i have checked all the fuses and are ok.
Thank you for your input

Woooooohooo found the reason for the car not starting. I found the other fusebox under the dash and one of these fuses was blown. Thank you DaveW for heading me in the correct direction and all others for there input.

Well done!!!!
Very satisfying to do your own troubleshooting!!!!

Only 28 fuses after all.

All I have to do now is figure out why the fuse went.
