Hi Everyone.

I bought my Omega at the beginning of July and it seemed all was well for the first couple of days.  I'm not a very mechanical person so I booked it in for a cambelt and tensioner change for the following week.

Then the day before I took it to the garage it started to cut out whilst at idle.  It would do this only every so often.

The car went to the garage and had the cambelt and tensioner changed and they said thay would have a look at this 'cutting out'.  They plugged in a diagnostic computer and this came up with a 'RPM/TDC Sensor Fault'

I couldn't afford to get this done at the same time as the cambelt so I had to wait until I got paid.  I went back to the garage last week and booked the car in to get this sensor changed. They checked again with the diagnostic computer to see if it was still reporting the same fault and it was.

Now things get interesting.  

I had noticed a smell of petrol when getting things out of the boot a couple of days ago and didn't think much of it.  But when I got back from the garage I could smell it quite bad.  I got down and had a look and could see a small puddle forming underneath the car (towards the centre level with the rear wheels).  Not being very mechanical I asked my mate too have a look for me.

I now know that the leak is coming from what I think is the fuel filter (well almost certain thanks to the 'how to guide')

My questions are.

Would this be enough to cause the car to cut out at idle or is it likely to be a combination of both?

I need to get the car back on the road as soon as I can but I can't change any of these myself as I'm not confident in my ability to do so.

The garage have quoted me £125 to change the sensor.

What would I expect to pay for the fuel filter change?

Any help would be most grateful.

Cheers

Niether of these jobs are that difficult to do yourself. Fuel filter will cost around £12-£15 & crank sensor is about £40 i'm sure you & your mate could do it along with the excellent guides on this site. Crank sensor would cause erratic idle & leaking fuel filter wont help things. Might also be an idea to remove icv & give it a blast with some carb cleaner

As well as replacing the crank sensor, chek this out:

Thanks for the information and the replies...

I've had the sensor replaced and the 'cutting out' has stopped.

The fuel leak is a bit odd.  It's completely stopped.  I've run the car a few times and drove it to Penzance and back yesterday (30+ miles) and not a drop, no smell nothing.

I think it's still a good idea to change the filter and I'll do it when I get back as I'm going away on Thursday.

One thing that I didn't mention before is the coolant level.  I've needed to top up often but I've had no obvious signs of leaks, no water underneath car, no wet areas under the bonnet.

Got the garage to do a pressure test today and they reckon a have a very small leak from the electric water pump.  He said it took a while to find and that it's seeping out.  They reckon a new pump will set me back £104 + VAT.  Does this sound about right?

I'm quite happy to fit it myself doesn't seem to difficult a task.

Cheers

Get a 2nd hand pump - they are realiable enough.

Thanx for that...

I'll have a look about for one and see if I can save myself a few quid...
