no start/possible fuel pump problems

I have a '93 xj, 317km on it

Driving home from class today, my jeep just stalled on me and wouldn't start back up. It would turn over just fine, but absolutely no firing at all, even letting it sit and cool down for a while. I have previously installed a fuel pump shutoff switch, and I get 0V at the switch as its turning over. The fuse is fine as is the relay (i'm assuming) since I switched that out with a spare from another jeep here, and its still a no-go. For diagnostic of the fuel pump, i ran a 12V feed from the battery to the load side of my cut off switch, and I heard my fuel pump kick in and start pumping. Turning the key, however, I can't hear the pump at all. I just installed a new TPS ~8mo ago, so I find that unlikely... What else should I be looking at? Thanks

Where is your switch? Between the relay and the fuel pump? Check for current going in to the fuel pump relay socket.

my switch is down by the door. I'll check that right away

CPS

Fuel pump should run while cranking if it is only CKP (crank position sensor).

I have 12v to terminal 86, 30 and not 87 when the key is on

So that part is good. Now when I asked where the switch was, I meant what wire it is in. My guess is that it is in the wire between the relay and the pump. When you put power to the switch, the pump runs. So something went wrong between the relay and the switch. Check the connection where the wire to the switch was spliced into the vehicle harness. Have you tried jumping around your switch in case it just went bad?

yes i checked that, because when i originally checked for voltage at the pump, it was really at the feed side of the switch. The switch is between the relay and the pump, yes

I wasn't given a 'check engine' light originally, but I just checked the codes (the old fashion way - key on/off), i was give a code 32 i believe which is:

32 (1990-92) computer didn't see change in air/'fuel ratio when EGR activated - check valve, vacuum lines, and EGR electrical

what does this mean?

Code must mean the EGR isn't working right, but that can't cause your problem. You've got to trace the wire from the switch to where it's spliced in towards the relay.

93 doesnt have an egr system, only the 87-90 have egr.

well in case anyone is wondering, I swapped out the CKP (crank position sensor) and it started right away and is now running fine.

Thanks for all the help!
