The ram 500 in question was traded by me to Cole..It had the latest version from Bob...This was a turnkey jet....It started perfect every time...Of course you have to no how to start it and to use Jet A fuel and not kerosene...If someone went and reprogrammed or was using kerosene,that will have an effect on the glow plug...Also once the plug was burnt,You cant just stick one in without adjusting the filament...You also need to turn off the propane once it ramps up...Propane runs hotter...All this stuff I showed your wife during the swap in Albuquerque ...She will attest how easy it was....I will offer AGAIN to trade back if this is not for you...
