I hooked up the batteries and turned the key on, no wait light...I went ahead and tried to start it and it cranked over great but wouldn’t start. I tried twice before I got the idea of taking my glow plug card out of my M1028. I swapped it out and turned the key, wait light!! I cranked it and it tried to start but wouldn’t. I checked and made sure diesel was in the tank and tried again. It tried to start immediately but wouldn’t. I tried again but this time gave it some throttle while cranking and it fired right up! The bad news is it will not idle. It will only stay running if you keep your foot on the throttle. It is slow to rev if given full throttle and is also puffing out bluish white smoke... So, do you guys think I need an injection pump or do you think I might get lucky cleaning the check valve on the return line of the injection pump? Thoughts?
