Ok, half hour left at work and with a bit of exhaust hanging around i decided to have a play.

First i found a spark plug the same thread as the old HEGO senser, a coil, battery & my trusty power probe.

Now the coil packs i'm using are from a 2.3 scorpio with two connections, + & -. When powered up i don't get a spark, this could be to duff plug, not enough amps from power probe or low voltage, although i assume even though it's a coil pack it'll work on a 6v principle.

Next item was a XR2i coil pack with the plug shoved straight into the top of the coil which when probed up created a very small spark, & not all the time.

Sooooooo are coil packs rigged up like this never going to produce a big enough spark which is why afaik all flamer kits come with a oil filled oil, or am i just doing something wrong? Or is it likely a duff plug!?
