had another go at my car tonight and traced a fault back to the ECU. basically i still had no spark on topacks. i checked the ignitor and didnt have a signal on two wires. i did a contunity test on the wires between the ECU and the ignitor and there all fine, so...

Is my ECU playing up??

OR

Could there be a sensor that is failing to triger two of the four ignitor inputs??

its weird that two work and two dont. Has anyone else had this problem??

 

ANYONE??

could it be a crank sensor or would that cause all four to fail??

 

Crank Position and Cam position sensor need checking first.

 

How do i check them? i done the resistence check as per the manual and they showed up fine...

 

Do you have access to an oscilloscope to look at the crank/cam sensor waveforms? A multimeter that can measure frequency and RMS voltage would do at a push...

Do you have a spare ECU you can borrow? It would help eliminate this as a cause of the problem.
