I like the green chassis, my chassis is blue and red but I just picked up a full green set on eBay for .99 cents. So it cranks over but does not start, when I got this truck the engine did not crank at all and I think it was frozen but I disassembled it completely cleaned it well, out a new glow plug in. I had to tune it but it runs well. These engines seem to run better on true rich side. Might got through a few glow plugs doing it but. You might have to buy a new piston and cylinder set or have it pinched. Good luck any I the questions just ask.
