Fill the tank up!
Then crack #1,3 & 4 injector lines. Then bump the starter, let the LP run, do this about 3 times, then try to start it until you get fuel out of the injector lines. She should try to start. Give that a shot and see if it works.

Have you tried having this code cleared from the computer? Sometimes stored codes can screw with things.

When I put my Fass 150 and new VP44 on I had to bleed everything! I loosened the front bolt on the filter to bleed there first till I had fuel coming out the line that feeds the VP44. I bumped the key to get the lift pump going, and once fuel started coming out I tightened it down. Then I cracked #1, #2, #3 , and #4 lines loose to the injectors. Cranked, let the lift pump run, crank, let LP run. Just bump the key by the way. Did that over and over for about 20 minutes, then tightened everything down once I seen fuel oozing out the lines. Then bumped the key again, let the lift pump run, then after it shut off, I cranked for 15-20 seconds intervals, till it fired up about the fourth interval. If it starts to sound like its gonna kick over, just keep it cranking til it fires. Just try not to crank over 30-40 seconds, gets the starter hot real fast. The whole process took me about an hour to get it running again after all the new parts install.
