It's a 90' zero mile 4.0 rebuilt motor. I finally got it started but its got a miss that i havnt been able to figure out. It has a new fuel pump, cap, rotor, wires, spark plugs. Dist. rotor is @ 5 o'clock when @ tdc, so i think the timing is ok. Firing order ok. I checked every cable to cyl. for spark and they all have spark, but i noticed that when i removed the #1 cyl cable there was no change. I removed the spark plug and saw no sign of fuel burn. I reinstalled everything started the truck and disconnected the injector still nothing. I changed the injector still nothing. Dont know what else to do PLEASE HELP........ Thanks.
