Omega General Help / Re: Turns over but won't fire? HELP!!

« on: 28 May 2008, 13:53:45 »

Sounds like same prob as i'm having but i got a code 74.

Try removing pipes leading to inlet plenum and see if it starts.

Mine does doing that.

Going to try another MAF sensor when it arrives.

Blocked or too dirty air filter?

Faulty air flow meter?

Well when i did clip test faults came up on TPS high voltage and  Mass Air flow sensor High voltage.

Could it be that then?

Before these probs the idle when warm was irratic going from 1000rpm up to 1600 RPM and back constantly.

Had another try to get Omega going today.

Checked all the Vac pipes and all ok.

I could only get the car to run when I removed the Ram pipes from the Inlet manifold.

Also would only idle if pipe from ICV was removed from ram pipe.

Any ideas?

I suspected the TPS to be suspect with my first problem of the idle going up and down from 1000 to 1500 RPM when car was warmed up.

Right not used the omega for 3 days as it is P*****g me off.

Started up today, was very lumpy and runnig rough cold.

Was also popping back through the air box and inlet pipes.

Set off after 3 mins, got as far as half a mile and it cut out.

Stuck just turning left at set of lights looked a right K**b

Tried starting wouldn't have it and stank very eggy.

I though it may be the cats but it wouldn't start at all if completely blocked?

Could it be Lambda sensors?

I'm considering getting rid cos i don't need this hassle when going racing next weekend.

Think the diesel Vectra is going back on the road!!!!

To get by, spray WD40 at pump shaft seal, through the holes in the pulley or from the back of the pump.

It is quite noisy but only just started.

When i rang parts place they needed a number off the pump to match it up.

Said there are about 4 different ones?
