Coil Pack Upgrade

I have just put a new engine into my hill climb car and it was starting up fine on the base map on my Emerald ECU, I was just about to get it booked in for mapping and now it won't fire up - nothing has changed since it last ran a couple of weeks ago except it now has no spark so I am thinking the coil pack has failed

I thought I would take the opportunity to install a new external coil pack and leads but I'm not sure what I need to buy etc. - can anyone offer any advice

quite unlikely it has failed, if it hasnt been mapped its probably fouled plugs.

there are no 'upgrades' for the coils, none will make more spark than the original one.

Thanks I know its not an upgraded coil as will only spark the same, I meant alternative coil pack

I'll whip the plugs out though and see - thanks

It is common place to use the 8v/Saxo VTR coil and a set of leads from a Vauxhall.

I use an 8v coil on my rally car but after serious research, asking questions and buying many
sets of Vauxhall leads I can confirm none of them fit the head correctly.

I then had some custom leads made to my specs for a perfect fit each end.

For me 4 individual leads on a competition car is a must so if you have a missfire you can
pull the leads one at a time to find the offending cylinder plus its quicker to change plugs
than having to unscrew the coilpack bolted down to the head.

Thanks, who did you get to make up your leads?

I have cleaned my plugs up and the car has started up now, but still want to change over to the separate coil pack especially as you say its easier when diagnosing issues, is yours just a standard 8v coil pack

I had leads made here in Ireland but can have a set made for you if you like.
Does your head have the collar sticking up from the plug holes?

Yes I have an 8v coil on my 106.

It's unusual for a whole coil pack to fail at once since it's 2 coils in one pack.

I'd be checking for signal from the flywheel sensor and it's wiring.

Thanks for the reply, I'd already checked for the fly wheel sensor through the ECU and all was fine, I cleaned up the plugs and got it running again so was just fouled up plugs thankfully

Now to get it mapped properly - thanks again
