Help! Help! Omega 2.2 petrol auto 2002
« on: 26 July 2022, 12:48:21 »
I bought this car while back to drive when I get my impending knee replacement op. I have been driving it a few weeks and the engine light was coming on when starting so was clearing it each time and it was a dream to drive, sooo I thought I would be clever and change the cam shaft sensor cos thats the code I was getting P0300, bought one and fitted it and it would not start, put old sensor back and still nothing! It seems to have petrol on the plugs but doesn’t sound like it’s firing. The coil pack was not touched when I changed the sensor, frankly I am stumped! Any suggestions as to what I may have disturbed?

P0300 DTC is a missfire related to more than one cylinder, nothing to do with camshaft sensor.

For a no start i'd be looking at the crankshaft sensor but a 2.0 / 2.2 will usually start eventually even with a duff crank sensor.

I think it'd be worth reading the codes again before going any further.

Not on the 2.2.

Does the fuel pump run when you first turn the ignition on?

If yes, level the car and try starting it.

Yesterday I went through basics, it has fuel on plugs and has a spark, has voltage to new cam sensor, I have checked timing belt and the marks don’t seem to to align , but I cannot see how or why it could have jumped teeth

When the camshafts are by their marks the crank mark is not pointing straight down as I think it is supposed to , it points to 4 o clock ( how do I upload pictures?)

I would create a free basic account on an image and/or file hosting site. Upload your photo images or other files. Then copy and paste the links to the images or files into your posts on here. Try imgur.com or Google Drive or Dropbox. There are others.

My conclusion so far  ( will do a compression test when I find my tester) that the belt was loose and has jumped slightly and now I have some bent valves. The car is too good to scrap and nice to drive so I may tackle it myself or if I can find someone to do it pay them.
Does the haynes manual cover the 2.2 or has anyone seen a guide anywhere? I imagine it will be straightforward though

The 2.0 16v is essentially the same engine  ;)
