Since no one has offered you any ideas let me see if this helps. Assuming your statements are all true and that you have a good charged battery. You've already ruled out everything but a bad ECU. Assuming the car ran before you did the HEI mod, the bad ECU seems unlikely. So I would like to hear exactly how you determined that the issue is the signal to the HEI and not the HEI itself or how it was wired to the distributor. Also when you say you checked the connections, did you eyeball it or do continuity checks, or check for voltage on the wires?

i had the hei module before when the trouble strarted i bought a new hei.

the problem didnt resolve.
i have a kf ignition with extrernal coil.
have 4 wires in my disty




disty connector
earth.
12volt.
5volt. pulses 6 times in 360degrees
5volt. pulses 3 times i think 120x3=360degrees

i checked the connections with a multimeter.


what i have already done
new hei and rewired
swapped kf01 distys
new rotor arm
new disty cap
sparkplugs and ingnition leads.l
swapped ecu
checked earth points

I suspect your not getting much response on your issue because it's in the wrong forum, You might want to repost this in Engine Electronics/Tuning forum.
