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.

Hi Sue
Have you got the wiring diagram? There will be one on RAVE. It will have the wire colours on it and I find it helpful when tracing wires around.

There’s nothing wrong with the ignition switch, if as u stated “starter motor turns over quite happily”
Iffy immobiliser maybe. Install a temporary wire from the vehicles battery+ to the ignition coil + and try starting. If the engine still doesn’t start, the immobiliser isn’t iffy.

Thank you. Will try that but may have to wait till next week if I need a multi meter anywhere as mechanic friend can't get back till then
Yes got the Rave download will try checking further. Thanks
Hi there. Mechanic put a power supply to the coil and it didn't change anything obviously and still wouldn't start. Good news for the immobiliser but bad news for the starting. Thanks for the info

Has it run since the ignition components were replaced?

Are the plugs wet after cranking?
you initially said there was no power to coil and no spark at plugs. you've run wire direct from battery to coil - at this point do you now get a spark at the plugs when you crank the engine?
if theres now a spark, then if its been sat for a long while, the petrol could be stale
It was running with everything but the new ignition amp
Honest answer - I'm no longer sure, will need to double check
Need to double check with mechanic as I was turning ignition key and he was checking spark etc. Last ran 17 days ago
No points - it's electronic ignition and original one was as well
thank you. You have confirmed for me it should start on petrol anyway. Fuse checked but next is change fuse holder as it's an old one
true to form my darling vehicle has changed the goal posts. When RAC checked it when I originally had problems about 20 days ago it had fuel to the rail, just tried it now and nothing there. Plugs are also dry. Petrol and LPG in tanks

So focusing on the petrol side, you have no spark and no ignition!
I would work on the spark first then give it a squirt of brake cleaner in the intake then try it.
To me gas is a secondary issue once it’s running on petrol.
Do you believe the static timing is correct and do you believe the engine has healthy compression?
