Took the plug out of the MAF and it made no difference at all, Dave I will take each individual plug out to see if all of them are getting hot, how is the best way to check them?

With voltage applied, a brief touch with a thermometer will quickly confirm correct operation - don`t worry about how hot they get - they either heat up or they don`t  - its as simple as that.

Dave do they have the same cam sensor on them like mine, as the engine would turn over but not start, no codes came up but found that the cam sensor had gone, just a thought. mk1 cam sensor, fixed the cam then crank sensor was gone to but got them both replaced, then no codes.

The engine will start but it takes a lot of cranking to get it going.

is there a pre heater or something on the o/s front on the 2.2diesel.that smokes when working

Rusty, Not that familiar with the Omega engine, however, now you mention it, I had a crank sensor on a VW Beetle Turbo fail on me last year, and when it finally did start, gave the impression of rough running like incorrect ignition avance but gave no fault codes either though VAG-COM.

I thought Tech2 was a little more advanced though, and should be able to confirm a crank sensor failure ?

Certainly wouldn`t rule it out though - good thinking !

When it starts it runs really well.

When it starts it runs really well.

so it dose run then, check the fuel pressure, if the pump is low there is not enough pressure to run. and a faulty cam or crank can somtimes take it's time to go, then the ecu turns off start.

[andy4775]

Rusty, how can I check the fuel pump pressure ?

[rustym95]

not that formil with engine but there should be a valve on the injector line will have a tyer cap on it need a cloth and push in the valve.

[rustym95]

found a pic of it its on fuel line has a plactic cap on with 13m i think, valve in side.

[andy4775]

I have found it Rusty, but don't know what I am doing it for, what will this show us Rusty.

[rustym95]

if the fuel is under pressure, how meany turns dose it take to start engine?

[andy4775]

Rusty it depends how cold it is, if its brass monkey weather like we've had, when it's really bad it wont fire (and l have flattened the battery) but usually about 6-8 times on an average cold morning.

it may be the fuel heater then pe-heats the fuel before getting to the glow plugs, can try this turn key to 2 leave for a minute then try it, bit longer than normal to start, there is some one on here that had fixed his but cannot remember the post. my old car had one and you have to give it a little time to work

That used to be the way to start many diesels a few years ago, turn the ign on so that the glow plug light was lit, and wait 30 secs before cranking.

Is the fuel pre-heater similar to a glowplug then ?
