[D1 RX7]

Car has now been off the road for about 2 months and i cannot figure out for the life of me, why its missing so bad...

For some reason, the trailing coilpack is getting VERY little to NO power at all. If it sparks at all, the spark is very very weak, and i get no tacho feed in the car. If the coilpack does fire the trailing plugs, as soon as u touch the accelorator it stops entirely.

Also, the battery seems to be draining itself, if u leave it sitting for over 2 days, ill need to charge the battery.

Ive tried so far:

Sonic bathed injectors
changed coilpacks
changed plugs
changed leads
tested all the earths
tried a different battery
tried a different ECU

im running out of ideas?! can anyone suggest something i may have missed, its driving me inssannee!

check the wires going from the ECU to the coil packs with the car OFF by checking resistance for high resistance or opens to determine if there are any broken wires.
