It just quit

My wife was driving the MJ home from work and it just quit. It was running and now it won't start. I am not going out in the dark to F#%$ with it tonight but I would love if someone has any ideas on where to start in the morning. Its an 88 2.5l w/ AW4 in an MJ. I guess I should look at the NSS and the ignition, but I did not smell gas in the TBI when I took the cover off. It was at around a 1/4 full on the gauge so I tried to add fuel but it still does not smell like its getting fuel. It will turn over and tries to start. but it does not fire. Any ideas?

check the CPS.

Thanks. I will chk it. Do you know what the voltage should be and what the Ohm's reading should be when its tested?

between A and B in the plug about 200 OHMS
