4.6L won't fire after rebuild
Truck = 1998 F150 with 4.6L Windsor SOHC
I just completely rebuilt the engine including pistons, rings, timing chains (timing is good; compression @ 180 psi), 2 new coils, wires, plugs etc. and there's no fire at the plugs when I crank it. It turns over good but doesn't start. The fuel pump comes on and there's fuel up to the injectors. Before I disassembled the engine, it still ran good except for one piston. The 2 new coils, wires, plugs were replace before I rebuilt it. I was very thorough when re-installing the electrical etc... and triple checked it all after the engine not firing. Fuses are good. I know it's hard to trouble shoot without seeing the truck but I'm just looking for ideas? The battery has been disconnected for months as I started a long time ago. Computer maybe?
