    If you didn't replace the fuel pump wiring harness when you changed the pump; that could be the cause of the problem. The pump wiring harness is a known defective design on that model. If that is not the issue, try replacing the spark plugs, plug wires, and distributor cap. I would strongly recommend Champion spark plugs for this motor; either part # 13 or # 3013. The 3013 is a platinum electrode plug, and will last longer.
