Hi all,
Just managed to get this up and running in my old 1.4 corsa sport.
It runs for about three minutes and then cuts out 
My mechanic and electrician are checking all buts like earth, pumps and everything but wondered if anyone has any input on what it might be?
Far as i'm aware there are no EML showing.
Cheers,
Steve

Is the EML light working, i.e. does it come on before you start the engine?
Also once its cut out does it restart easilly?

EML on start works in prior checks.
It's easily restarted again just decides to cut out!
Im thinking it could be the 1400cc fuel pump? Either not 100% suitable or knackered?

1.4 16v pump will be fine..
Does the EML flash when it stops?

No EML flashes when cut-out no.
Could be just the aftermarket regulator needs adjusting?

Does it just cut or is it spluttering?

Far as i was told it cuts out with minimal spluttering.
Maybe the EGR valve too come to think about it?

EGR will only put the EML light on, you dont even need it.

Ah right, I may actually take that out to save weight!
I'm thinking it maybe the aftermarket FPR jobbie may not be set high enough so shall let them know. There's a gauge on there thankfully!

EML will be on all the time though.. Best thing to do is just blank it off or fit a manifold that has the return blanked (this is what I did)..
What is the guage on the FPR saying?
If the FPR is at fault (pressure to low) the car wont rev and you should get a lean mixture fault.

Normally if thats the case its a wank-bag to restart from warm  worth a try though.

Just unplug it. Car responds better with it unplugged = you know the fault.
The ECU "substitutes" values for the sensor when it's unplugged.

It's the regulator! The guy has got to find the correct pressure and so on to get it correct and should all be ok then
Thank you for all the input so far

Ok update on it. With setting the regulator it's either overfuelling or underfuelling and it's quite sensitive when trying to adjust it.
So would setting the regulator down slightly to make it underfuel but then raise the revs slight do any good?

Put a standard regulator on instead of what im guessing is an fse adjustable one? If you need a standard one im pretty sure iv got one here.

It's a general aftermarket FPR. Not the flashy one.
Is very similar to this one:

The FPR needs to be T pieced onto the fuel feed, it shouldnt be inline.. How have you got it setup?

Right.
The regulator if set "just" under this "magical" line will make it under fuel. It ticks over all day long but as soon as the throttle is put down is starts to splutter and soon after cuts out (as if there's not enough fuel)
But.
Putting it up a mere niche up it over fuels. In this case the car will actually drive and they have driven it but after a few minutes of driving it and after returning it to the garage, it's stinking of petrol and I think they mentioned a little bit of petrol escaping through the exhaust system and course this would eventually end up drowning the spark plugs.
At the moment the regulator has been taken to vauxhall (they know a guy) so the regulator can be "put on a bench" and adjusted to exactly what they need.
But from everyone else's experience is this the regulator at fault and if so should I get a better quality one or is there another underlying fault?
Cheers so far all
