Still going around in circles here, you can link it to anything you want until cows come home. But until you get a proper code diagnosis your pishing in the wind!

yes, you are right !!

i dont think it is a fuel supply issue, i have changed out the pump/relay/fuse. should it prime even with sensor failure ?
i am used to BMW's, not used to Vauxhalls. its weird.
why would the trip/clock zero as well ?
could water ingress cause an issue somewhere ?

Flat battery or dodgy connection. Have you checked all the fuses?

Other than that, as already said, you need to get the codes read properly

[markrnorton]

Is there anybody out there in OOF land that can help read the codes on my car please with a tech 2, I'm in Essex and would be grateful

thanks

Right... Been to look at this today and the only code was to replace ECU

Live data shows a cranking RPM and fuel pump activating. Confirmed fuel at the injection rail. Nothing looks untoward on live data when cranking.

I'm thinking that cam sensor is a likely culprit, although no code knowing that these are the weak link in the 4 pot engines. Mark agreed with me that it seems most likely so has ordered one as a starting point.

Hopefully an update to follow...

Oh, and thanks for the tea

 It's about the only sensor to fail, think it would even start with crank sensor disconnected. When genuine sensor started to go, would cause hot starting issues. (lots of cranking) - maybe when they fail completely it's cold starting

Thanks for taking a look Paul.

I'll fit the crank sensor saturday and report back, hopefully its just that.

Was really expecting to see a code but it just wasn't there

As I said yesterday, I had to collect something from South Benfleet anyway so no hardship to pop over

Update on this thread !
Still not working after a camshaft sensor replacement

also on cranking now, its not showing a cranking rpm (whereas it did the other day when Paul had a look)

with fault copde cleared again its still reports back original diagnostic 'ecu re-programme or replace'

Is it likely the crankshaft sensor is the fault ?

any ideas ??

Important thing to note on this is that it doesn't appear immediately, only after a few hours minimum.

It's got me a bit stumped TBH, although I'm not very good with the 4 pots

Was the cam sensor bought from a Vauxhall dealer, or from somewhere else?

[markrnorton]

Genuine vauxhall Sensor from a dealer

[markrnorton]

Just to update this thread
spent a few hours changing the crank sensor, what a nasty job (what madman at Vauxhall put it there)

anyhow car still will not start, i have to go to the ecu now, take it out and apart see whats what

[markrnorton]

Final update

Bought a complete ECU set from Twiglet on here, fitted it tonite , and started first time !

wooo

its rolling again

So , there we are , the "My Naff Code Reader" diagnostic was correct, replace ecu.
the old one must have been toasted

Good to hear you got a Result at last Mark
