I'm not too sure if the coil side is run via a relay but I don't think it is.
On my mates the wires were slightly broken up on 1 wire I think, Looked at it a few times and thought it was fine until we'd practically given up then I spotted it.
Check to see if the earth wire on the coil amp is getting a good connection. Could be a poor earth.

ino mate im not far away either :(

i was thinking wiring or relay iv had a quick look around at the wiring and it all seems to be ok but im not really sure what im meant to be looking for, is the fuel pump realy the only possible relay it could be? or should i check any others

Shame you can't drive it here. I have a full working dizzy engine here you could spend a day swapping parts over from.
Worked out on my mate Xe Vectra.

Sounds like a dodgy relay or wiring to me if it works sometimes then doesn't.
Try wiggling wires whilst someone turns the key.

yeah it was getting 12v to the coil and then it wasnt, really temprimental!! its weird but i cant work out why! sometimes it was getting it and sometimes it wasnt!

all my mates with valver corsas are running coilpacks not dizzys :(

Sounds like you have the newer style FPR, the original brown one was known to be faulty.
On my old Astra GSi the FPR went but worked sometimes, Way to tell if it would start was if the ECU came on, No light it wouldn't fire.

Not a definite way to spot if the FPR is fubar though.
You not got someone with same engine to swap bits over with?

Have you checked to see if you're getting 12v going to the coil?

FPR is black mate just hanging around by the gear box on the loom.

Dash lights work aswell its just not sparking,

it did fire up once last wekk but aint got a clue how i made it do it lol

What colour is your FPR?
When you turn the ignition on but don't crank the engine does the ECU light come on?

ill look into that tommorow mate, also trying to get hold of a new ecu and fuel pump relay

Yup that's what i'm talking about mate. We had a very slight spark, No where near enough though.

yea iv pulled out the spark plugs but theres no spark, the king lead from the coil to the dizzy isnt even sparking, so you mean the 4 pin plug that comes off the loom and plugs into the coil amplifier? and a red and blue wire come off that and onto the coil itself?

Is it a dizzy engine?
On the dizzy engines there is a plug that goes into the coil base, Think it's 3 or 4 pin. If you pull back the rubber casing off the end of the plug and check the wiring and test the wiring with a circuit tester. It may not be your problem but only takes a few mins to work.

Have you pulled out a spark plug and checked the spark when cranking?

ahhh ok mate could you explain in a bit more detail what area i need to be looking at as ill look into this, not quiet sure where u mean lol

Check the plug to the coil. My mates started playing up. The car was running spot on until we swapped cams then it wouldn't start, There was very little spark.
After hours of swapping everything over from my XE we found a dodgey wire.
Worth a try.

dont know of anyone who has one for a dizzy engine :( hassle!! would the ecu cause it to not spark?

ecu possibly then? can you try another?

sorry forgot to mention has a brand new one of them too

crank sensor or crank sensor wiring. if it cant see a signal from there it wont spark

Hi guys iv been trying for ages to get my C20XE corsa to start and it just wont, it was running fine and for some reason it just will not fire up and i have tried everything i can think of and now im going to have to give up and ask for help :(

Its turning over fine and the injector rail bleed nipple is showing its getting fuel but its not getting a spark at all.

I have fitted the following all of which are brand new...

Coil Amplifier/trigger-ignition pack
Coil
Leads
Dizzy cap
Rotor Arm
Plugs

Anyone???????? :(
