Model year is irrelevant. Do you have a front mount distributor or the angle (side) mount style? Are you trying to run a 12V switchover system or is it the OEM 6V/POS GRN setup? Either way, have you verified the wiring is all correct? Don't guess and start replacing parts until the true root cause is determined.
