clutch interlock switch?

I hope one you experts out there can help me out a little bit. I have lately have been having trouble with what I assume to be the clutch interlock switch on my 2000 TJ 4.0 liter. The jeep won't start, pump the crap out of the clutch and bang the shifter around for a while and sooner or later it would start. I installed the 20 amp fuse for the bypass per the owners manual but I'm still having the same issue. The clutch itself is in need of replacement if for no other reason the high mileage on the TJ (155,000 miles) if that might be a factor in the non starting. Thanks in advance for any and all help you might be able to give me.

It could be the ignition actuator pin. The tip breaks off and the broken end will sometimes get lodged just right in the slot of the ignition switch enough to turn it, then sometimes not. Check out the thread below.

Well the saga continues. I replaced the ignition activator pin and the ignition switch to no avail. The jeep still will not start without pumping the clutch and banging the shifter around. I'm hoping one of you might have an idea where to go next. And again thanks in advance

Jumper the clutch switch and see if that fixes it.

Shifter has nothing to do with starting.

Check all your battery cables and grounds as well.

Could be a bad (worn brushes, corroded connection) starter/solenoid. Can you put a test light on the small wire on the starter and see if it is getting juice all the way to the solenoid? The physical jarring of pumping the clutch and banging the shifter might be establishing an intermittent connection and allowing it to start.
