87 auto Okay new plugs and leads Have replaced cas bearing plug and sensor. Have swapped coils transistor and ecu with known working ones. Realigned the notch on the dizzy gear and the rottor buttons facing 1. On cap Have swapped around 3 dizzys (whole unit) all have same results =no spark from coil.. I have a muti meter and have swapped my fuses and checked fusible links.. checked for cotinuity between coil wires, transistor wires, cas wires and ecu . So.... here i am asking what else is there to check? Definitely getting juice and possibly an injector leak juging by tge smell After cranking. I've pulled code 21 from the diagnosis test on ecu. ignition signal missing? Ive read about a diode being a possible cause but unmasked earth wire from batt to block an couldn't find anything other than the earth wire.. . Perhaps it was previously removed? Any help /advice very appreciated cheers..
