I have been trying to get my 16v swap started and the knock box is only sending 1.3 volts to the hall sender and full battery power to the the fuel pump relay (which should be the ground for the ignition switch current needed to trip the relay)
is there something that would cause this behavior? or is the box its self bad???
any suggestions or ideas are welcome
also if you have a cis-e knock box for sale i would like to buy it, if mine really is bad.
the brown wire with a yellow tracer goes to the knock box @ pin #10, it has to be ground in order for the fuel pump to run (jumped it to ground and the relay goes if the ignition is in the running position)
as this diagram describes
at pin 9 a wire that is also brown with a yellow tracer leaves the knock box and provides power to the Hall sensor.
currently the brown/yellow wire to the fuel pump relay is grounded when the key is off, and has battery power when the key is in the running position which it shouldn't.
there is only 1.3 volts getting to the hall sender while 12 volts is going is going to the fuel pump relay.
also i have 12v switched coming in through the yellow wire
i did continuity checks on all the wires that would be questionable and they all check out with next to no resistance.
i started this thread to make sure i'm not chasing down the wrong problem, has anyone else had the knock box fail on them? i bought this motor in running condition (from someone the vortex).
suggestions are welcomed i don't know what i'm missing if it's not the knock box that's causing the problem.
I'm not trying to convince everyone this is what's wrong, i'm just trying to provide as much information as i can to help people make suggestions or help me trouble shoot this.
tl:dr fuel pump does not prime or run because the knock box is sending power somewhere it shouldn't.
