I just got up the courage to go out to the fj and cut and splice the ground to the fuel cut off solinoid. I cut the black and white wire and patched in a new ground. Now the f'r won't stay running and there is no click anymore when I unplug and plug the green connector back together. What do I do now?
what do you mean by patched in a new ground. You sure the ground is making metal contact. Try undoing it and connecting somewhere else. Do you have a voltmeter?
I think you have a ground issue. Does the plug only go on one way or can it be reversed.

I now have the black/white wire cut and the green wire cut.
If i touch the power line from the battery to the carb side of the black/white wire
the sloenoid clicks
If I touch the power line from the battery to the carb side of the green wire
the solenoid clicks
neither have a ground at the time of contact with the battery power line.
If I touch the power line from the battery to the harness side of the blk/white
there is a LOUD click under the headlight washer resevoir.
same if i touch the green.
Almost as if a ground isn't needed.
BUT, if I touch the green to green and black/white to black/white nothing.
The green and black/white wire to the solenoid you got confused. One of them is ground and what happens is the emissions board switches the it to ground to open the solenoid. If you connect the low side to ground then it will stay open all the time...
Why did you splice one to ground? Since it wouldn't open? I wouldn't run like this.. that is unsafe since it stays open all the time.
If the solenoid is not opening, then you have a wiring or emissions board problem. First check your fuses. Then rewire the wires to how they were on the green connector. You have a multimeter? Maybe it is time to buy one. If you have one turn it to read voltage (DC), unplug the green connector from carb and stick the two leads on the wiring side coming from emissions computer not the carb and it should read 12V or -12V depending on which way you are holding on the leads. If you are measuring 12V then turn off the ignition and make sure it goes to 0. Sounds like you have a problem with your emissions board.
Ok, before you tow it. Pull the cover off the fuse box and check the fuse for the engine...I grounded the positive on the FCS before and blew a fuse....Yes i know real Smucking Fart.....But you might have blown a fuse check it out...might be an easy fix..(fuse panel is to the left of the steering wheel)
For the down and dirty method of grounding the FCS just lay the wire in the negitive side of the plug and connect the plug back together and run the wire to a ground.
i know what hes tryin to do. there was a thread i was in, where we were asking how to test to see if the idle cutoff solenoid aka "fuel cutoff solenoid" is grounded properly. the ground wire is the WHITE wire with a black strip down the side. everything else is hot.
"Wiring on solenoid valve ( LC in general)...White with Black line is 'ground', any other color is 'hot'.
To test solenoid: unplug from harness
jump white with black to ground (- terminal on battery...)
tap a jumper green to + on battery and listen for click . . . "
BUT, the body side wiring for the soleniod is
- Green to control conputer ( thru puter to ground when engine is running
. . . . .puter 'opens' circuit if engine vac high ( compression braking)
- Black w/ yellow line : Hot with key in 'run' position
Because the system is direct current, testing the solenoid by applying power to it when 'unplugged' from harness...doesn't matter green or ( mine is crappy whitish...both are in a 'sleeve') goes to hot, other to negative or visie verse . . .
But be careful tinkering with the harness side of the connections..
As yourname learned...key on...black/yellow to ground...poof..time for a new fuse...
As fer go'en ter work...
"Got an eye problem, can see comming to work today" . . .
