Title: won't start x30xe omega
Post by: djhorner on 20 October 2013, 18:44:38

right after months of i got head gaskets sorted on the mv6 but when i came to start it , it ran really rough then wouldn't start after we figured out leeds were in wrong order and we hadn't fitted vac pipes properly but now everything in correct order there is spark and fuel but will not fire just turns over i tried bump starting but no luck still won't fire up ideas

Something still not corrected properly - most likely a plug, but if you've already checked, could be anything. What else did you move when you rearranged the leads?

we took all leeds off and did them one by one as per coil and cam cover firing so on drivers side 135 and other side 246 is it possible that a faulty crank sensor would stop it from starting

Worth checking codes again, timing correct? fuel getting to the injectors?

Quite likely (especially if the lead was disturbed while you were working on the plug leads).

A faulty crank sensor doesn't always bring up a code. I found when one of mine failed that the EML light stayed on when the engine was cranking. With a new sensor the EML went out as soon as the starter started turning the engine.

I would have another look at the plug leads before condemning the crank sensor though.

I think this shows the correct order for the later DIS pack

I had an early (1994) V6 with the coil pack bolted to the head and the leads coming out horizontally towards the bulkhead.

Later ones had a shelf with the coil pack sat on top with the leads pointing vertically.

[sorry, I can't bring myself to call it a DIS (digital ignition system)]
