Jim, when you had it plugged in, did you test to see if the throttle position sensor was working?

Seems odd the pedal trick doesn't work, and along with the non-start? 

[darren757]

Yes put new crank sensor in .
Will check plugs etc

Good news got it to fire up for a few seconds by using QuickStart straight in to throttle body so it seems to be fuel ..I will put some more fuel in but what else could be preventing fuel getting in to engine with code issues not reading could it be throttle potentiometer

Using that stuff is generally not reccomended here

Hi yes I don't like QuickStart but it proved one think no fuel .

As I can read codes i am
Thinking potentiometer ..is there any way to test ..I will check fuel first dispite what guage says.

Only with TechII, or 'other' software designed for Opel.  Some ELM327 readers will do it too.

Afraid not... That stuff is so volatile it ignites under compression so it's proven either no fuel or/and no spark

Unfortunately we ran out of 12v's for looking at much live data.

[darren757]

Thanks for all the info..QuickStart is 50 percent do methyl either and whilst it promotes ignition on a petrol engine the compression ratio isn't high enough for it to ignite..the only reason I know this is the research a friend of mine did and it's ignition promoting qualities on compression engines !!

When I have a mo and some daylight I will take potentiometer off encase it's stuck or there's something obvious but other than that I'll need to substitute it..

It would be nice to get to the bottom of this!!

Is the car level? Put at least two, preferably three gallons more fuel in and give the bottom of the tank a whack as you crank it... If it fires fuel pump needs replacing, if it doesn't then try the two purple relays... One controls the fuel pump, tother the injectors. They can burn out...

If you have an Android phone or tablet and want a cheap way to see live data then I find that Scanmyopel https://play.google.com/store/apps/details?id=com.ScanMyOpel.Main&hl=en_GB will show throttle pedal position.

I think that the throttle pedal has two potentiometers and the output from both has to tally else it brings up an error code not at all certain about that though 

[darren757]

Ok just done a bit more.
No fuel present in either fuel line to injectors .
Plugs bone dry but correct colour.
Can't here fuel pump running when I turn ignition on.
So if I am correct its pump or relays for pump .

Where would I find relay for pump.
Sorry just seen previous post car is level and quarter of a tank of petrol .

[darren757]

Sorry forgot to mention spark is good

Get a meter out. Start with the connector under the inspection panel in boot floor.

[05omegav6]

Add more fuel, and try test above...
