Are you sure it's getting fuel? Do you hear the fuel pump when the
ignition is switched on? Is there fuel at the injectors? Are the
injectors plugged in? (I know but often it's the stupid stuff that
trips us up!)
Are the spark plugs actually getting spark? I know of a guy who went
through this and it turned out the contact in the center of the
distributor cap had fallen out.

The engine was supposed to be a remanufactered original jeep engine. I
had thought that the engine was 180 out and rewired it to find out if
this was teh case and it still didnt start. I have the #1 cylinder at
TDC and the rotor is pointing at the knotch on the distributor. I have
the firing order memorized as if it were my SSN. 1-5-3-6-2-4. I have
tried moving the wires one forward and one back. Still nothing.
