unless the fueling is different on a 2 litre 8v to the way a corsa works i'd just go with the gsi pump.... I.E reconnect the fuel pipes without that other pump under the bonnet... see what happens...

firing order? timing p.s any fuel pump will do untill the revs get so high i.e even the 1.2 fuel pump will make it idle fine and not to sure about the internal 12 i think early models had an external one, check the conection on the afm very common on the 8v also i had a simaler prob when the ecu filled with water cause the ruber gromit was fubar

dump the 1.2 pump all together :thumbs:

i very much doubt he put the 1.2 pump in the engine bay aswell as they are internal pumps. (need to sit in the fuel tank)

1.0 toy peice of poop

Bad earth? You have wired all the earth straps down off of the engine?

Electronic fault? Crank position sensor?

ok cheers. so thats one thing it can't be. lol

na, thats what ur fuel pressure regulators for

would the extra fuel pump cause it to miss fire though? Could it be overfuelling and flooding one of the cylinders?

yes, gsi pump would be fine on its own

Mine only fired on 2 cyls. 2 dead injectors, so I just got some out of my spares and it's all happy again.

you bought a 1.0 in disguise

change one of yer ht leads on a working cyclinder onto the one that isnt working..

its something simple i'd say...

[Edited on 30-11-2004 by Siberia]

check the dizzy cap, ht leads rotor arm, buy a can of wd40... and the engine code is c20seh i think, the 130bhp one :thumbs:

Recently got the 2L 8V engine from a cav sri put into my corsa.C20NE i think :boggle:

Basicaly its running like a bag of shit. It worked perfect in the cav which is annoying me. all the plugs are new and tight, any ideas on why its only running on 3 cylinders? Wired in wrong? Could it just be something simple like distributer cap and HT leads? however surely they will be working fine if this problem didnt occur in the cav?

Any help would be appreciated. cheers
