So this is what has been installed on the car, MSD Blaster coil, MSD 6AL ignition with an MSD 8534 distributor. The ECU box looks like it be original (or very close to it)
Thanks for the response, I’ll need to do a bit more investigating so I can be more descriptive. I’ve only had the car for a year and 6 months of that time the car was in winter storage. The car has been heavily modified. I’ll absolutely check the grounds.
Thanks
Hello, I have a “71” 340 Demon that has intermittent ignition spark. I drive the car for 20 minutes or so and it will just quit. After the car has died I can wait a while, maybe 20-30 minutes and it flashes up again, any suggestions ?
Thanks
