I just rebuilt my nephews 91 5.0. New crankshaft, e303, gt40 heads/intake, rings, pistons, bearings etc. Nothing special. I have everything installed and the car cranks a little slow and won't start. I have spark at the number one plug, firing order is right, and i made sure distributor wasnt 180 out. When cranking I am getting fuel dripping out of the drivers side header(they are open). This doesnt seem right. I checked the injector connections with a test light and they are pulsing just fine. I had the injectors cleaned and tested during rebuild. The only other thing I can think of is maybe the timing marks were off when I put the timing chain on but I know I can't see me doing that. I'm only thinking that because it seems to crank slow even when jumping it. Any ideas that I can check?
