We switched them they had a spark now they dont so am thinking if its the wires that carry the msg from the ecu to the coils to fire that is giving this problem cause am getting 12vlts on the wire that carries the power to the coils

 

Do you have injector pulse?

This situation sounds familiar. Is there a thread here about this already?

 

Yea i have injector pulse only on 1 & 2 cylinders along with firing but no injector pulse or firing on 3 & 4

 

ECM is probably bad.

Swap with a good one to test, if you have one.

Is it a 954?

 

Yes it is a 954 we swap the ecu & tried it in mines & my bike started right up so its not the ecu anymore ideas to what this issue is 74demon

 

Check the connectors for a loose pin and continuity through the wire ( injector driver and coil driver) from the ECM all the way through the injector harness.

 

Ok will do that now & i will check for continuity from the ecm through the wires to both 3 & 4 ignition coils also to make sure am getting continuity all the way through

 

you should have 2 wires, both ground circuits.

The 12v power side is good.

 

The black wire with a white stripe is the 12v power wire that goes to both the coils & injectors am i correct

 

Well i have 12v on those black wires with white stripes that are going to the coils & the injectors which would be the power wires
