@holly1catherine ,Catherine, Ensure battery is fully charged. Trouble bleeding air out, just barely crack open each fuel line (one at a time) right at the injector while someone cranks the engine over. As soon as you get fuel coming out tighten it back up again. If no fuel could be plugged filter, clogged/damaged/pinched fuel line, faulty pump. The link below has a really thorough write up on bleeding/trouble shooting diesel fuel system approx 1/2 way down the page. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
