I have a 97 xj I drove it one day and the next day I went to move it but the fuel pump didn't run, the fuel gage didn't move and the voltage gage didn't move, it will crank but won't start. I replaced the crank sensor but that didn't do Anything, any ideas?

Refreshed your grounds?

PCM Had the same issues with a 98. Bought a cheap used PCM plugged it in and fired right up. I think with a 97 you can use a 97 or 98 computer. Look at the numbers on the outside and try to match them or do a search for your year.
