Hello all,

Bought my first omega today,brokedown after 5 miles,cant really complain though as it was dirt cheap

Car was running fine,I stopped for a few minutes then went to restart it but it just span over and wouldn't kick in again,sounded like it was almost going to fire a couple of times but just wouldn't

Plenty of petrol in

Was thinking some kind of hotstart issue?I had to dump the car and head home so can't confirm if it does start cold until I travel the 100 miles back to it

Is there any common failures on these that anyone can Think of?cheers

Crank sensor. Dead

Crank sensor... buy a genuine one from a genuine VX dealer that you genuinely have to go to

Can also check for codes using the paperclip method

[chrisgixer]

See the guides under code reading. 19 is, you might of guessed, crank sensor. Typical symptoms by your description anyway.

You haven't said what age your 3L is, but I have a brand new un-used genuine GM crank sensor still in the GM packaging bought as a spare for my 1996 3L, yours for £30 posted.  I will check on the part number and advise.

Thanks chaps,all very helpful

It's a 99 T plate

And yes I would be interested if it's the right one

Can they be changed without going under the car?

[aaronjb]

Not exactly, but if you know where you're looking you can do it by laying on the ground beside the car and reaching in around the back of the nearside front wheel..

Alank46, if your Crank Sensor is the Bosch one with the chamfer on the end (part number eludes me temporarily) and the OP requires the other type could I 'basgsy' this, please? Of course if the OP requires the Bosch type then that's fine - I'm only casually looking for a cs at the right price as a spare one only, I have no imminent issue/need. 

[alank46]

My sensor only has a GM marking, its 90492006, and it does not have a chamfered end.  I'm not sure if it is suitable for a 99 T plate, perhaps somebody can advise.  Its the oblong plug type.

I also have a brand new non-genuine crank sensor for £15 posted.  I used to carry it as a spare in the car in case of breakdown on the move so to speak.

Genuine one should be ok for '99 3 lit

No worries, then. However, I seem to recall there's every possibility/probability that this one may be suitable for the OP. Think it was MarksDTM who made a post some time ago - possibly in Howto or similar - detailing the differences between them. I can't seem to find it, but it is out there. 

I know that even if you go into the dealer and give them your reg etc there's still 50/50 you get the right one, it's a case of seeing what's fitted, and getting the same one again.

[omegod]

I believe the MAF plug is the tell tale, rounded corners or square corners dictates the sensor type

[Diamond Black Geezer]

Yes - that's the feller! I second that. 

OP - Follow the airbox down the ducting towards the engine and you'll find a plug and wire, that's the MAF. Apologies if you already know that, I mention just in case you didn't 

[Merlindriver]

I was once told that a clue to a failed crankshaft sensor is when you turn the engine over there is no movement whatsoever on the tachometer (or rev counter if you prefer ). Certainly when mine went that was the case and on the few occasions it has been hesitant to start there was a least a little jump of the needle as it turned over.
