Should be 12v or there abouts. Check the fuel pump relay.

[Sir Popple]

Wellung, thanks for all your help, can you point me in the direction of the fuel pump relay thx

[Sir Popple]

Thx On my way to check

[Sir Popple]

OK i have fiddled with the fuel pump relay tapped it, smiled at it, and talked to it encouragingly and woe and behold she started ran for 3 mins and cut out !! how do i get this relay out so i can test it on the bench. Thanks to all

[TheBoy]

It does just pull out, but they often stick.  I'd get a replacement from scrappy, then it matters little the damage you do

[Kneepad]

It just pulls straight out but can be difficult, try getting a flat blade screwdriver under it and wiggle it upwards.

[Welung666]

I've got a couple here if you want one sending Sir P.?

[Sir Popple]

OK, Thanks to all again, here we go for another day of playing... I would love to get parts from Scrappy but i am stuck in Ireland !!! Thx

[Sir Popple]

Here we go again.. The relay works fine on a regulated power supply on checking the feed to the relay on the car i am only getting 0.33 volts when cranking the engine. Any ideas anyone?

[Sir Popple]

Please read the post before this, i have tried holding the Fuel relay in manually which does run the fuel pump, and then had the bright idea of holding the fuel pump relay in manually while cranking the engine to see if it would start but it didn't,

Crank Sensor?

I know they are troublesome on the Omega, but I had the same problem on a Beetle with burning out a fuel pump relay due to a knackered crank sensor - spent hours on that bloody relay only to find it was something else.

[Sir Popple]

Thx, that is what i was thinking, is there anyway of testing it?

I think Dave has probably identified the most likely cause.

The lead to the crank sensor degrades due to the heat from the exhaust manifold and disturbing it (by wrestling with the cam covers) can be the final straw.

Not all failed crank sensors bring up a code. When mine failed it didn't.

What I did notice was that with the failed sensor in place (and the engine failing to start) the engine management light stayed lit while the engine was cranking. With the new sensor fitted the light extinguished the moment the starter engaged and started cranking the engine.

As already said the ECU doesn't run the fuel pump unless it can sense the engine is turning.

[Sir Popple]

Andy, Thanks my engine light is staying on when i crank it as well. I am going to order a replacement part from Auto Vaux today unless someone advises differently. They have quoted £28 plus £7pp to Ireland. They want 93.17euro over here for the same part!!! Thx to all again, Steve
