2.0 16v petrol, X20XEV with Siemens Simtec 56.0/56.01.
Out of the blue no start. Fitted a new fuel filter. It started. That felt like £6 well spent !
However next day, no start. Thinking I was on the right path, fitted a new fuel pump. Still no start. That felt like £27 wasted !
No spark, fuel to the rail but dry plugs, so no injection.
Paperclip test says codes 38 91 and 92. Discounted 38 and 91, the Oxygen sensor as would not prevent start.
Code 92 points to Camshaft sensor and duly fitted a Siemens part. No start.
No new codes. Unable to clear old ones using the 30 times ignition on and off rule.
Am moving to getting a Crankshaft Sensor as it is number 1 on the 'Most Likely Route Scale'?
Am I in the right direction?
How do I clear codes without TEC 1 /2 ?

I think fuel filter only go one way round. You havent put it on back to front have you? Not sure if that would stop it working but as its the only thing youve changed and its stopped working I'd look at that first.
or if no spark id say coil pack

Where did you buy the Camsensor from :-\ Genuine, from your local VX dealer recommended... and with good reason :y

No Start with Good Spark.
The GM system on these cars is a "Bypass System"
The ECU has nothing to do with Spark Control until after 200 rpm or so.

Meant to mention...
Most likely cause is reference back to the ECU
My Firebird has 2 fuses in it for the ECU on the main fuseboard, one hot at all times and one hot in run only,
Having only had my Omega for a couple of weeks I haven't looked closely at the Omega System but its worth a check into, I had the same problem with the Firebird, turned out to be a 10a fuse!!
Might even be an immobiliser issue?
Cheers

Cam and crank sensors always favourite on X20XEV
And as Al says, genuine only, not something that the parts traders tell you is genuine or OEM manufacturer.

In reply to threads poated.
The cam sensor was new and marked Siemens and identical to the part I took off.
It has started once since the new fuel filter. I now have fuel at the rail a la pushing the fuel decompression valve shows a decent spurt of fuel.
So I am looking at what will cut out spark and injectors and thinking crankshaft sensor as 1) cheap to buy and try 2) has a bad reputation for failure.

I agree crankshaft sensor is likely culprit. Buy genuine Vauxhall, will cost about £75, and it is tricky to fit.
