I had a similar fault on an old p38 and it turned to be a corroded battery lead from the battery to starter motor the leads corrode inside the insulation I just doubled it up never had an issue again might be with a try

Update

Whats happening etc
Multi meter oot

OK, no power getting to solenoid.
Bridged it.
And it fired into life.
So, starters ok.
A few possibilities.
Relay.
Fuse.
Chaffed or broken black power wire.
Faulty ign switch. (££££)

Noo,
Need to take the rocker cover off and look.
Then if needs be,
Need to trace and find fuse/relay.

Weil done to the young AA guy as he was straight into the case, trace and eliminate. Made in Scotland frae 'Girders'

The following diagram is the key one from the workshop manual.

Given the symptoms you describe, and here are 3 key elements to check.

1. Fusible link 2 60A in passenger compartment fuse box. Given the original intermittent nature of the problem, it is very unlikely to have failed.

2. The ignition switch itself. If I had to guess, I'd say this is the most likely problem area. Some people have had success with contact cleaner / lublrication through the keyhole itself. If so, that would be a result - cheap and quick solution.

3. The immobiliser ECU. Not much you can troubleshoot with this. I think it's eliminate all other problems and replace this only as a last resort. It will need to be coded to the car.

The starter relay appears to be within the starter motor itself, so the AA diagnostics have ruled that out.

Of course related wiring fault is always a possibility, but eliminate the ingnition switch first. If it's wiring, it could be quite hard to find.

Awsome. Thank you
I have been using a screwdriver this morning.
Bought a couple of connectors to 'hot wire' it till ah trace fault.
Great info and thank you for yer time.

Only thing I aint tried is the box behind battery.


PS. Just been oot and hot wired the solenoid up to a switch in the cab.
At least that does away with screwdriver.

(Wonder how long it will stay like this? LOL)

Oiled the ign switch, no change. Made in Scotland frae 'Girders'
