Hi! I'm new here. I was told this was a great place to get help.
My problem is as follows:
I have a 1999 model Omega B 2.0. Recently it started cutting out some times when idling. It just died, and it was very hard to get it started again, but I managed get it started again every time. Seemd to be worse when the engine was warm. Once it cooled down, it would start perfectly, No problem. But the problem has just goten worse!
Now it's almost impossible to start! Even when cold.
When I crank the engine, it get no spark (I tested the spark with a test-lamp between the plug and the wire while cranking) for 10-15 secounds perhaps, then it get spark, and not again.. It seems to randomly miss, and I get engine knock due to spark at the wrong time when trying to start. Also, the RPM needle in the dash stays at 0 when I crank.
Once it's started it will run perfectly. It's just the starting that's messed up.
I did the paperclip test and it gives me the 0335 code. Crank sensor. But I can't test while the engine is running. So is the crank sensor bad? or is it just telling me it is because the engine is not running when doing the test?
Do this car have both a crank sensor and a cam sensor? Why will it run perfectly once started (no miss or whatever) but be so hard to start? If the crank sensor was dead, wouldn't it run poorly as well?
need some advice here! :\

They can be a pig to start with either the cam or the crank sensor failed / failing, if you lose both you won't be able to start it.

A 0335 does mean that the ECU is unhappy with the sensor (for whatever reason, but usually is the sensor itself), not that the engine simply isn't running :y
-
As VXL-V6 says, they can be a pig to start if unhappy with sensor. Sometimes, unplugging the duff sensor can help you until you can replace the sensor

*SOLVED* :y
Well, I went to my wauxhall dealer and bought a new camsensor. Jacked up the car and started to search for the sensor which I believed to be near the oil filter. But no. It was near the exhaust manifold. And that discovery also made it very clear that the wauxhall dealer had given me the WRONG sensor! even though I showed them the car, with the engine code and all..
Anyways, Since I couldn't do anything about the sensor, I started checking that everything was in order since I had the car jacked up anyways, and I noticed that one of the bolts holding the starter motor was a bit loose. I made sure it was in correctly and tightened it. Tried to start the engine, and voila. Engine started right away. And the fault-code was gone.
Don't make much sense how the starter motor affects the camsensor? they are on oposite sides of the engineblock, but as long as it works I'm happy. :y

That's the crank sensor on a V6 :y :y

I watched them punch in my engine code. And still they managed to give me the wrong sensor... ::) Nice going! And this was the local wauxhall dealer.. :P Good thing it was such an easy fix though. I was affraid I would have to change cam and crank sensors. :y
