Omega General Help / Re: ignition on syl 2 and 3 only

The spark plugs are new.

There are three wires to the dis module. I believe one is signal for syl 1&4, one for 2&3 and the last one is ground.

I think I'm missing a signal from the ecu. I've measured the signal from the ecu when the engine is running (on 2&3), but I was not able to recognise any problems with a voltmeter. must probably have an oscilloscope.

Is the crankshaft and camshaft sensors the only input sensors that controls the ecu's ignition output?

No, thank's for the tip. I was suspecting a ecu fault, so I tried another. I could not start the car because of the "start security device" (dont kow the english word). But I had sparks on 2&3 with this one as well. The dis unit is new.

I'm checking the spark. new leads. I've not checked the resistans in the cables, but i've cross swiched them.

I have ohm'd the cables to the ecu, they are ok.

Thank's for quick reply. I can start the engine on the two sylinders. The light on the engine lamp goes off when the engine starts. History fault codes are 19 and 92.
