these will run on 2 cyl very roughly while the air is purged out, but if the pump is not creating enough pressure will not inject the fuel into the cylinder, IIRC. I can take a few pictures of the troubleshooting guide if you need it, but I agree with above, its air in the lines or timing.

Other things to help us, is there any smoke? if so what color?

knowing it was apart, is it possible the cam is out of time?



I will leave my 1st gen manual on my desk until tuesday. if you need procedures or anything from that, reach out to me in PM or tag me so I get notified, and I will post the procedure from the book.
