Fuel cutoff relay?

would an 87 cherokee with 4.0 have the switch that kills juice to the fuel pump upon hard impact? If so where is it?

Not unless someone added it.

Well that leaves me stuck. this thing ran before it was rolled on a backroad, now it will run on starting fluid but there is no juice back to the pump....

replace the relay?
Check the ballast resistor on the drivers side fender, if it's there. My 87 doesn't have one, but I understand that the dealer would put one on if someone complained about the fuel pump noise.

this is my first cherokee so I'll have to search to see if I can fidn that stuff. Whats the resistor, if its there, look like?

looks like a white block on the drivers side fender. At least that's what I've been told. I don't have one myself.
The fuel pump relay should be the second one from the front. Swap it with another one and see if you get power. I went through the whole fuel pump circuit late one night with Langer1's help.
Things to check.
Fusible links. I Believe that it was a green fusible link, with a red wire.
That should supply power to the relay at all times.
Check for power at the tank, the 12V wire should be orange. I also had another conector behind the seat in my MJ, I don't know where it would be in an XJ.
I started at the rear and worked my way forward until I found where 12V stopped.

Thanks a bunch, I'll see what I find.

I don't think any 87's had the ballast resistor, unless it was added later.

I think your best bet is to trace the wiring as 87Manche suggests. It shouldn't be too hard to find your way forward. Make sure you check grounds too.

I had an '87 and rolled it off a freeway after an arguement with black ice and I remember that they said something about needing to reset an automatic fuel cutoff that is enacted during a rollover. I don't now how the reset was done though. Good luck

ditto.

There are a couple of old threads that discuss this.

Good luck searching.
