My jeep wont start I have a 93 jeep CJ the engin rolls over like normal, like it is going to start and then doesnt. I have checked the fuel relay it is good, i sprayed starter fluid in to the tunnel that leads to the engine and it didnt start, i ran the engine test and it came up with 5 5 which means nothing is wrong... it feels like the engine isn't getting any gas.. any suggestions?

Does the fuel pump cut on when you turn your key to the on position?

do you hear the fuel pump kick in when you turn the key?....you should....are you sure it is a fuel problem??...have you checked the coil?...perhaps you have no spark

What engine do you have?
My 4.7 did this and it turned out to be a CPS "Crank Position Sensor"
For the straight 6's ... the 4.0's, it's likely to be the "Cam Position Sensor"

If it isn't a fuel issue, my next step would be to get an inline spark tester.
