Crack one line at the injection pump and crank with a helper. It's probably extremely air bound, so you may not see fuel for awhile. Crank for 10 seconds of time with a 20 second rest so you don't burn the starter. It will start again, have faith. The IPs barely ever go bad unless you pump WVO thru them.
