do these have a fuel pump relay like a valver???? id check power to the ecu also.

If its not even got a diag plug then surely there could be cicuit/continuity issues with it, could you not source another loom if all else fails or was it a runner on this loom in the other car?
My best guess is still on the crank sensor though bud
Jack, i'm not sure which loom you are using? c25xe, x25xe or x30 xe?
All the earths on the engine good?
As thats where the coilpack earths through.
And aye you could have 12v to the pack, but the pack could still be knackered. You dont usually find a totally dead pack though, usually only one coil fails. Did you check every plug for a spark???

Right, to answer some of the questions as some people must have missed some of the posts.
We have fuel
I have just changed the crank sensor
We have changed the coilpack
Changed the ecu
changed the cam sensor
Earths are all good. Switched live and perm live are all good. (to the point ive buzzed through all of the wires to the ecu plug, including all of the sensors)
It WAS running in the doner car, however the loom was all over the place so I tidied it up. As I said, i was very careful when I did this and every sensor and power connections are correct.
The one thing niggling me is the coilpack was bolted to the drivers side inner wing on the doner, so I relocated it back to its correct position on the pass side of the front bank and extended the wires to it.
COuld a change of style of wire cause a problem? Ive used the same guage but the wires are not the same consistency of wire (ie the original sensor wires are stiff, whereas the extention wires ive used are softer). Could this cause an issue?
If the cam sensor and crank sensor are out of sync (timing issue) would it stop sparking but continue to fuel? ALthough i doubt thats the issue, it turns over perfectly (you can hear its right when youve been doing it long enough)
The doner came to us without lambda sensors and didnt seem to effect how it ran so i cut the cables back (allowing for re install if it ended up needing them). ANything special I overlooked there? I know it should still fire without lambda, but im seriously starting to clutch at straws here!
Thanks for the help so far guys
When I couldnt get my C16 to fire up, oddly enough when I flashed the ECU light off it did then fire. Just use a bulb off the brown/Yellow wire & see what happens......
Any use dragging it up the road wth a rope & making it GO?
Indeed, i plan to wire up the EML first job tomorrow so we'll see what happens. Trouble is, ive no idea what wires to bride to flash any codes off. If it ends up being that though, Jack is going to stick his strut brace up my ass for making him buy all these spare bitsOriginally Posted by craig green
Its cranking fine craig, I doubt a bump start will do it
My memory is poor when it comes to wire colours etc, but tbh I didnt understand the EML bit on mine, as the dash wire doesnt seem to be on the main plug on my GSi yet the old ECU used to operate the light properly yet any conversions I've done have about 3 extra wires for EML off the ECU loom. Pretty sure I chucked a test bulb on the wire mentioned, the bulb flashed with the ign & that time it started from then on. Like it just wanted to flash the bulb & then all was OK.
Brown/Yellow to earth to flash codes.
ECU light is brown/blue.
Get the ecu wire wired up, as it can really be helpful!!!
No lambda sensors shouldnt effect it running, and if your getting fuel then the ecu is "seeing" the crank sensor signal... So that should rule that out too.

Not really anything left to change that would stop it sparking though
