Ecu is mkc103400, engine is in a kit car, so no fobs or immobiliser.

I’ve tried several coils. There’s no beg pulse to coil from ecu. I’m thinking ecu fault as well..

I’ve got a reply from Paul, “I don't believe this is an immobiliser issue as the engine ECU only stops
the injector drive when immobilised, the ignition coil drive is not affected.”

I have tried to contact him. No reply.

Crank sensor has been tested . There’s signal to ecu plug.

Had a look, injectors are not firing. Plugs are dry.

Yes that's for the map sensor but you'll still have spark. Are the injectors pulsing when cracking?

Yes

Just read about “ecu vacuum connector”, does that need to be connected??

Yes, no spark. Wiring checked, coil checked. Fuel pump primes, have fuel pressure, coil has feed, ecu not switching the coil.

Just checked, ecu is Rover M.E.M.S, mkc103400, crank sensor has ac voltage to ecu plug. No spark..
