My Sdk8, with a toyota diesel requires a lotbof cranking to start. Temp was 60f. I am thinking the gliw plugs might not be working. Also any ideas about throttle pidition. I was doing it full open and anout half didnt seem to make a difference. Re started ok but not great when warmed up. Just bough it so have not idea the state of things, but it ran nicely once started.
as long as u know how to post pics.. how about 1 of the engine & fuel system.?? Glow plugs are easy to check but u either have to have a battery charger or some wire & alligator clips OR a volt meter.. IF u have a volt meter, set it to ohms.. disconnect it from the common electrical rail it u have the type that connects them all.. Hold the lead to the top of the GP & 1 on the body.. U should read less than 2 ohms. anything over & its bad.. IF u DONT HAVE a volt meter, ur gonna hafta takem out.. apply 12v + to the TOP & - to the body.. it should get cherry red in less than 10 seconds.. IF 1 or 2 test bad, REPLACE THEM ALL.. & keep the "good ones" as spares.. Let us know how THAT turns out & we can go from there.. OH, MAKE SURE your getting power TO THEM when u turn the key or push a button.. Good luck.
