1988 2.9l flooding
 

I pulled the engine to replace the oil pump an re-seal it. It ran great before it was re-sealed. The plugs, wires, cap, and rotor have been replaced. I replaced the ignition module and the idle position sensor. I did have it running enough to have it diagnosed, Can't rember what the code was but it was getting to much raw gas at the o2 sensor. I pulled the plugs and if seems to be getting to much gas. The fuel pressure at the rail is 40 p.s.i. Now it will not start. Any ideas?
