Hello,

I'm having a problem with my '95 Griffith 500, and hope that someone may be able to help.

A few weeks ago I started the car and moved it out of the garage, then left it running, suddenly it died as if the ignition had been turned off, then would not restart.

Last week I had some time to tinker so go out and had a look around the coil and ignition module, with a view to swapping the coil with a spare I had at home. Some of the wiring looked a bit tired so I tidied some of this up. The car then started, problem solved i thought...

Car ran fine for a few days until it died on the M4 again there was no coughing or anything just suddenly had no spark. I had a fiddle under the bonnet to no avail, had to resort to the AA.

The AA mechanic had a play around and tested a few bits, power to both sides of coil etc, suggested it's probably the ignition module.

I fitted a new ignition module yesterday, no such luck, I managed to get a spark for about 3 seconds then nothing. With the ignition turned on I have power at both sides of the coil, both sides of the ignition module, and all the way down to the last connector at the distributor.

The distributor is turning when the starter is turning the engine over.

Any ideas on what to check next?! Could this be anything to do with the ECU, does anyone have an ignition wiring diagram?

Thanks in advance for any help or suggestions.

Evening all, I had some time to have a bit of a play this evening, checked everything suggested and all seemed good.

I removed the alternator & bracket the check nothing was crushed and or damaged behind it, nothing obvious.

When I fitted the new ignition amp I didn't fit the new amp to coil connector and cable, decided to do this and re wire ignition amp to dizzy as well.

Finished this and it fired up immediately, inspecting some of the older wires there are areas where its clear they could crossover or earth so I think I've solved my problem!

Thanks for the help all.
