Hello everybody. I have a Yale GLP050VXEUSE086 (Propane) that won't start.Working fine previous day. Not showing any codes, getting fuel to throttle body and no spark. I pulled electrical connector going to coil to check for voltage with key on and get 12 volts for about 5 to 10 sec. then no voltage. At the same time that I lose voltage to coil there is a flapping noise coming from underneath throttle body. Could I have short somewhere? Thanks for any help.
Update. Noise I'm hearing under throttle body is governor cycling.
Showing items 1 - 4 of 4 results.
Ending up taking to dealer.Bad ECM. Thanks for all the replies.
have you got 12v on the post of the coil if yes, take off the main king lead lead and put a spark plug on and try if you get a spark look at dizzy if not the coilpack(Control) or fuse or the coil is u/s.
If you have a spark at the king lead look now at the dizzy cap and rotor arm, cap could be cracked andf going to earth.
If not look at the ppoints on the dizzy. and adjust up.
hope this helps
Did what you said. Still no start. Pulled one of the plugs out and reattached wire. Laid it on valve cover and cranked it over. No visible spark.
these trucks have a little pre heater in the fuel system. ensure you have a good battery , turn on key and count to 15 then crank. yes i know it,s a lpg truck but please try before ripping more of your truck apart
