couldnt find another mark on the exhaust wheel... ? anyway, SUSSED IT!!! It was the coil! It was firing, we checked that many times, but wasnt giving a powerful enough jolt to spark under compression, threw in a coil off an old 1uz (its done 10's, must be fine hehe) and it fired straight up, running perfect
Thanks for the help given.
For reference, i only doubted the spark when it wouldnt run the timing light. Checked the light on another vehicle, fine. The light obviously wouldnt pick up the pulse in the HT lead, nor in the coil lead. I guess there is a way to test the coil but it never occurred to me because it was actually sparking with the plugs pulled out. Tricky.
