My sons Griff will not start, there is a spark at the plugs, checked all the relays and fuses, petrol pump will not spin when you turn engine over but if you put a live feed to it it spins, so we are thinking it could be the inertia switch under the dash but can,t find it anyone know where it is located it is a 93 early 500, or fault in wiring or imobilser, any ideas please
I had this problem, Griff cut out on roundabout. Guess what it was? it was a loose connection on the fuel pump relay fuse.
I'm ashamed to say, I had just bought the car so it was the RAC who sorted this. I learned something from the RAC guy, he was very methodical. The first thing he did was disconnect the air intake and squirted Easy Start in. If it fired then it was a fuel problem not electrical. It fired therefore it was fuel!
He then worked backwards from the tank to the engine and as the car was fueled we soon got to the fuel pump which did not whirr when ignition turned on, then it could only be pump, pump relay, fuse or the (dreaded) immobiliser but as someone says this sounds unlikely as my immobiliser is only connected to the starter motor relay, no the fuel pump.
I hope this helps.

Took the glovebox out and no inertia switch, this is an early 500 and a bit of an odd ball, the alternater is on the wrong side, changed the relays checked the fuses and the fuel pump is still not spining, but it does when you put a live feed to it, going to have to check all the wiring,
The fuel pump only runs when you first turn on the ignition for a few seconds to pressurise the fuel rail. It won't run anymore until the engine is running.
When you first turn on the ignition you should be able to feel/hear the relay click.
Might be worth getting roverguage or ecumate hooked up if you can. They have the ability to turn the fuel pump on and off via the ecu which would allow you to test the circuit easily.

Yes been thinking about getting one anyway as I have a Griff as well, what is the best on When you first turn on the ignition you should be able to feel/hear the relay click.

Just to sure of the details here
He parked it and everything was OK
When he has gone back to it, it opens with the key fob and the indicators flash to show the alarm has disengaged
He turns the key to the first position and the dash lights all come on as normal but you can't hear the fuel pump prime
And the engine doesn't start when turns the key to the second position
Is that all correct?

If not the immobiliser, It could be the fuel pump relay or the main ECU relay.
If when you switch on the ignition and then switch it off you hear the idle control valve cycle in/out it could be the fuel pump relay, if you do not hear the ICV cycle then it could be the main ECU relay. They are identical and are the metal capped ones.
I had exactly the same thing on my V8S last year; put it in the garage at the start of the winter and it was fine. Went to start it in the spring and got no fuel pump.

Yes all as you discribe only difference is in Dans Griff you turn the key then push a button the dashboard, remember the photo and you asked what the button on the right hand side of the steering wheel its that oneHe parked it and everything was OK

Read page 1 of this thread GaryI'd say for a non-techie you'd be better with ECUmate because i think you're after the plug and play diagnostics functions of ECUmate.
Rovergauge looks interesting because of the amount of detail and a graphical interface but it looks too much like messing about with computers for you.
No offence obviously

I,am not too bad with computers and if it goes over my head my friends son will sort it out he builds computers,I'd say for a non-techie you'd be better with ECUmate because i think you're after the plug and play diagnostics functions of ECUmate.

Anyway what about non starting Griff ?
