My oil pressure switch(not the oil pressure sendign unit for the gauge) is not hooked up to anything and there is no wire anywhere. Does the computer control this somehow and they used a switch to cover the hole up?? Ive been tracing the 2 wires coming off the actualy plunger unit that cuts off the fuel and i tested it by puting 12 volts to it and its works it just ive traced the wires to abotu the fusebox now and i would have to cut up a bunch of that tape crap around the wires to keep tracing. Should i jsut test to see if positive is going to the plunger when the key is on and is so just cut the negative off the plunger and run it to the switch?? I have a problem starting my truck sometimes(like the fuel is getting cut off) and i think this is my problem.

 

alright its a idle cut off switch so it doesnt deisel not an oil pressure deal. Mine just doesnt click open sometimes when i turn on the key so i had an idle issue some times when starting the motor. the part is like anywhere from 25 to 50 so i know someone with a 22r from a close enough year and im getting a rebuilt carb with the piece i need on it for 50 bucks . If anyone is interested in a 22r carb motor and tranny let me know. Motor has low miles since last rebuild(rebuilt by a very good mechanic) and rebuilt 5 speed tranny. I forgot the price. PM is interested though.
