no spark

[Kevspec]

double checked all that and seems fine. gonna try another ecu but ive pulled mine apart doesnt smell or look burnt. does anyone also know which wires from the module go to the coil and what i should be reading maybe there broken cause im getting injectors pulsing no dramas

[delcowizzid]

The coil just gets 12v supply and the module earth's the negative. Make sure the modules you are testing are bolted to earth and the coil has a suppression cap on the positive to earth

[Kevspec]

I've triple checked everything no broken wires etc all relays and fuses swapped over tried another ecu with factory memcal and still got nothing. I've replaced so far brand new tested dizzy with new cap and rotor. Tried 2 different coils 4 ignition modules that I know work and another ecu

[vlad01]

Ignition leads?

[Kevspec]

I've tried a few different leads ive got laying atm just going straight from coil and nothing seems to make a difference

[immortality]

Checked the battery connections, block and chassis earths?

[Kevspec]

They have all been upgrade when new Motor went in

[delcowizzid]

Have you tested actual voltage at the coil compared to battery voltage

[Kevspec]

Yes all gets same voltage. Would there be any sensors that would effect anything I'm any way if there faulty. Mind you there are no codes and threw the software nothing is out of the ordinary

[delcowizzid]

Like I said earlier if the coil and ignition module have power and the dizzy is plugged in it will have spark even without any ecu or other sensors. Some models share the 12v with the Injector power you could have a shorted Injector may be worth pulling the plugs off them all and see if spark improves. Have you had the plugs out of the engine for a look
