[QUOTE="Bswwood, post: 112350, member: 17639"] The injection pump has an internal lift pump and that is usually the problem. Installing an electric pump will not work because the lift pump is stuck and fuel can not pass. Has the machine been sitting for a long time? I got one working again by filling fuel filter with Sea Foam, starting machine and letting idle until it shuts off. Let sit over night and install new fuel filter with fresh diesel, flush lines, and start machine and see if the internal lift pump will free up and start working. [/QUOTE]
