98 4.2 problems HELP!
Have a 98 F150 w/4.2L at. A few yrs ago it started giving problems. First one o2 senor then another an another.Replaced each as they appeared except for the last one(has 4 02 sensors).Then it started running rough.Then quit running.Fast forward to now.Decided to put it back on the road (setting 5+yrs)Dropped and cleaned the fuel tank.Installed new fuel pump/sending unit,tank pressure sensor,fuel pump relay, battery and gas. Wouldn't hit a lick.Checked fuel pressure. None.It will fire when I squirt gas AND starting fluid in the intake then dies. There is power to the fuel pump relay but not to the inertia switch.Given the 02 sensor problems first could it be the engine control module(power train control module) or does anyone have any other input?
