Got a v8 3.9 which aint starting recent rebuild and was running fine until it decided not to start. I have no voltage to coil ive lokked at the spider system and it's already bypassed . Turn the key and the fuel pump primes up . Its running a power spark distributor and the amplifier for ignition has gone . Disconnected battery and no joy even replaced the bats in key fob . I cant seem to figure out whats gone wrong . I have been having probs with the ignition key being stiff but it turns over so cant see it being that.any advice welcome .thanks

After more fidling I got power to coil but still no spark .rhink may have a faulty power spark distributor. Gona put old one with points on and see wht happens .hopefully it will start and drive
