Can anybody help with the wiring on my V8. I've stripped the LPG system off it today, and now it won't start.

No spark, but smells like fuel at the exhaust, so I think the injection is working.

The coil has 3 connector

HT - Fairly obvious what connectors are on there.
Positive - White lead, and Suppressor
Neg - Black Lead going uptoward Air Flow and White\Blue towards Dist\Amplifier.

Firstly is this correct, as I'm not sure we didn't disturb it when removing the LPG

Secondly how best to test it?

Just looked at mine for ya. Cables from the multi plug (5inches along cable from coil) white to pos. Black/white to neg. Single white wire coming from afm trunk to neg.

If it's a single point LPG system, mines runs off the coil to give the signal to the solenoid to cut the petrol off and start the LPG.

it's brown and red wiring I'm sure.
