You must replace the intake harness when doing the pump.it may look fine but inside could be fried.napa has a great harness for about $15

NOTE: I'm sure he meant IN TANK harness.

Check fuel pressure first [40PSI+] then check/change fuel filter, check the harness connection [in trunk-sedan or under rear frame rail-wagon], fuel pump relay and fuel pressure regulator- pull hose off end, it should be dry if not replace.
