Hi all,
can anyone help with my problem?
My Omega failed it's MOT on a leaky injector. I have resealed 2 of the injectors yesterday, and also taken the lid off the pump to clean the position sensor in an attempt to solve fault code 64.
The car will now not start.
I have cracked the lines that were removed and I am getting fuel there.
I have taken the in tank pump out of the car and tested it, it is working fine and I can hear it coming on with the glowplug light and running for about another 5 seconds afterwards. There is about 20 litres in the tank.
The car sounds like its trying to fire but does not start.
What should I be checking next? Could there still be air in the system?

Thanks
Dave.

Have you checked the leak-off pipes? It does sound like you have disturbed one, they become brittle when old, and snap of crack without being obvious. Have you released a union at the injector to make sure Diesel is getting all the way though the system?

[Dink]

All leak off pipes have been replaced with new in the last 6 months.

I have cracked the 2 injectors that have been disturbed and am getting fuel there.

Although I'm now thinking that as the pump was partly drained there could be air in the other injector lines?

[Dink]

Cracked the 5 injector lines I can access and am getting fuel at all of them.

My best guess is that it is probably down to air in the system - any tips on getting it out?

[zirk]

Are the glow plugs doing there job, disturbed them, wiring etc?, the 2.5 are a right pig to start in this weather without them.

12v from the top of the Relay to each plug, should stay on for about another 5 seconds after the GP Bulb goes out on the dash. or pull the top connector off the relay and measure each plug in turn to Neg, each plug should be 1 to 2 ohms.

Sounds like you have upset the positioning sensor this could turn out costly as you may find you need to take it to a specialist to be reset.
As for code 64 your best option is to just live with it

[Omegatoy]

you didnt mark the top of the pump? on your own head be it, but loosen the top of the pump and just tap it along a bit,if its wrong one way engine will start and rev its nuts off,if its wrong the other way no start, its trial and error from here bud, go careful you need to get it where it will start and tickover ,may still be wrong after that as it may be gutless may go like stink as said its trial and error

[Dink]

I did not remove the quantity adjuster from the pump, just took off the top cover.

It should not have been able to alter the fuelling at all, but I am worried that my investigating has caused a problem with the pump.

My mate is coming over tomorrow to help check the system is bled and attempt a tow start. If that fails I will most likely weigh it in as a pump recon or replacement will cost considerably more than the car did.

[Dink]

Have tried tow starting with no joy.

However it is now throwing a new fault code - 82.

Is this to do with the needle lift sensor or the crank sensor?

Thanks

I'd be checking the wiring/connections relating to No 4 injector VERY carefully as my next step.

IME '81' is the code for a failed unit.

[Dink]

But it should still start with no 4 disconnected?

Have been out to it, wiring is ok and am getting 90 ohms when probing the relevant terminals at the ECU.

Have tried to start with no 4 disconnected, still won't start and just gives code 81 as well as 82.

A friend thinks that 82 could be related to the crank sensor but I think this is highly unlikely? Surely it wouldn't attempt to fire at all if the crank sensor had failed and would give a different code?

No ... no 4 injector incorporates the 'start of injection' sensor.

[Dink]

Yes but I have had it starting and running before with that injector disconnected.
Running with CEL light on and at greatly reduced power but still runs.

[hoofing it]

As Seths says code 82 is num 4 injector if the crank sensor was at fault code 19 would show.
I still think that you have upset the main injector pump by removing the positioning sensor but another thing to try is take a direct earth from the battery to the casing of the ECU as you may off disturbed the ECU and its not earthing properly this might be the reason for code 81
