I'm pretty sure there is no spark did the basic lead
test, but how do you determine what the exact cause is?
I've tried another coil, still no spark, I've tried another lead still no spark
4x4 specs FJ62 F3 LPG/FUEL
Any one got some ideas on how to
check for faults, will try again in the morning
Can some one point me the right way to Electronic ignition please ( website )
TT

If new leads and coil still produce no spark perhaps the points have closed up or it's a rotor button/distributor cap problem.
One critical feature required by all LPG powered vehicles is a very good spark and keeping your ignition system in order really is important. Poor spark with LPG is the usual cause of backfiring and is common on LPG carby GQ Patrol's, the fitting of electronic ignition to these gives excellent results but whether you get the same benefits with your HJ60 I don't know.

Oops, sorry TT I didn't see you have the FJ62 but the same principles apply. Most of the Nissan guys convert their points setup to a Pertronix electronic system together with an extended rotor button specifically for GQ Patrols.
Ontrack Automotive in Ferntree Gully,
Melbourne sell them and they also have kits to suit Toyota as
well here's a link to their system.
Pertronix ignitor

check for spark at the points, ignition on and a screwdriver across the contacts, if nothing
check points contact area for pitting ,
check gap, cant remember
the gap but i would guesstimate 14 -16 thou, if points are pitted obviously replace, next suspect the ballast resistor, white ceramic with wires attached, if you have a spare try that one, dont forget condensor,
check the distributor shaft cam , they can seize, lube if suss and try turning the motor over and see if shaft turns , also been known to break, sorry if im wrong, diesel mech., but spark only comes from a few
places, and suspect the unexpected.

Lift distributor cap , look inside base section for a short insignificant looking lenght of wire .
Check end connections for security and condition . Wire can break where it enters the crimped connectors .

Hey there Tommy,
As a bit of a rule of thumb, 16thou for 6cyl's & 20thou for 4 cyl's. Normally that'll get you up & going.
Sounds like you've been in amongst it mate but hey, you came out on top!!
Get in there & have a go!!!
Regards
Dallas
