Advice needed please desperately. D1 1999 (1998 built) auto 3.9 V8 with LPG conversion - Leonardo 175. Won't start though started motor turns over quite happily. New dizzy, coil, dizzy cover, ht leads, plugs, rotor arm, ignition amplifier. Hopefully all connections checked and power etc checked by professional (i.e. - not me!). Had got petrol getting through but LPG gauge has no lights, doesn't seem to be the main fuse but may have another one I don't know about . No spark and no power to coil. Please has anyone got any more ideas, I've been reading all your posts and can't find one that sounds the same mainly because temperature doesn't make any difference.
