Only sparks when switched off!

3.5 SD1 in a P6 with optical lumenition. No spark at all except one fat one on switch off!
Managed to get normal sparking once when I bypassed ballast. Then blew the feed fuse and now can't recreate this.
Still sparks once on switch off. Swapped coil - it was wired to earth via ballast AND fuel pump in series, Not like the diagram I found at all.
I'm guessing wire coil direct from battery to rule out ignition switch and then bin the lumenition for neater Powerspark jobby?
