jono Posted December 8, 2017 Share Posted December 8, 2017 Long story short, my small engine spark tester is confirming what I thought first, I only get a spark as ignition comes off ! As I tried to start it it sounded as if it was about to fire yes CRANKS FINE thanks Wont fire to start, but gave a last ditch try to fire as I switched off sometimes Back story is this is my buttermilk in catch can ute Not on the road at present thank Fuji I always like to degrease engine bay before I get down and dirty I also like to wash and polish before I start things too So engine bay first I was able to start it at first today after sitting a while, few weeks, after sitting a few months beforee that Battery was a bit weak, so booster hoked up and she fired moved it, degreased and pressure washed the engine bay from top of underside bonnet to back of gearbox and down under the sump Gave her a pressure wash and chamois dry Then started a while say three minutes, then died. Yup, water under dizzy cap, so left it out in sun to dry inside of cap and dizzy itself Still no fire Loking at my propane mixer I wonder ...Jay Storer says never blame the gas first I undid the cover of gas converter to find good reason for an overhaul kit to go through it, first time in nine years 120,000km. Been sitting on a repair kit, had the time, so went for it. Overhauled the gas safety lock off too and just as well, its filter and bowl was chockers with dry mostly ferrous crap particles, never seen so much in my life !! Gas stuff all cleaned up and kitted, set up and back in Still no bloody start I am planning to first hot wire it to boot the ignition switch out of the equation and see if it starts then. Next will be swapp ignition switch BUT have a sneaky suspisicion this weird thing has happened to others before, cant recall, who or what. Maybe I need to chase up a module I have lurking Quote Link to comment Share on other sites More sharing options...
Knucklehead Saloon Posted December 8, 2017 Share Posted December 8, 2017 Ok 2 things spring to mind here mate. 1. Water inside a leccy connector and probably corroded in there too. 2. Coil or dist module bad. 9 from 10 they whack out once they get a little heat in them. Quote Link to comment Share on other sites More sharing options...
lrgvanman Posted December 8, 2017 Share Posted December 8, 2017 If there is a ballast resistor on the coil, check that. They are notorious for the secondary starting circuit failure. Quote Link to comment Share on other sites More sharing options...
jono Posted December 8, 2017 Author Share Posted December 8, 2017 Thanks. Can rule out ballast coz its module not points. Measured just under 12V at coil pos ignition on and just under 10 while cranking. Spark plugs all dry clean and near new Denso Quote Link to comment Share on other sites More sharing options...

jono Posted December 8, 2017 Author Share Posted December 8, 2017 Time for some elec spray stuff...maybe even more sun in the bay? Found two modules and two coils to swap in Quote Link to comment Share on other sites More sharing options...
Dee2 Posted December 8, 2017 Share Posted December 8, 2017 I'd let it dry out some more then see if it starts. Quote Link to comment Share on other sites More sharing options...
jono Posted December 8, 2017 Author Share Posted December 8, 2017 Took ten minutes to swap out the reasonably new two pin module and an old trusty Hitachi original - and SHE BANGS! Summertime here Dee, things dry out faster Quote Link to comment Share on other sites More sharing options...
DaveT Posted December 9, 2017 Share Posted December 9, 2017 Yeah, water and electricity don't mix. Quote Link to comment Share on other sites More sharing options...
jono Posted December 9, 2017 Author Share Posted December 9, 2017 Wasn't much water as such just the typical escape into the cap The offender Probably good fortune that I went through my fuel filter and converter Pic shows the crap that literally poured out of it in dry form Quote Link to comment Share on other sites More sharing options...
