We have a 93 Wrangler 4.0L Manual trans that won't start. It was running but it ran out of gas and now it will not start. The fuel filter, Plugs, Cap, and Wires have been replaced. We have 37 pounds at the fuel rail. and we are getting spark. The CEL is not on. The battery has recently been replaced.

Does anybody have any ideas what it might be? Does any body know of any wrangle specific forums? All I can find is JeepsUnlimited and that site is just aggravating.

Thanks
Chris

Is there anyway to check if the sensor is bad?

If the Wrangler has on have you checked the clutch interlock safety switch, as in it won't start until you depress the clutch ?

This test is for OBDII, not sure if it works on pre-1996

PROCEDURE
1. Near the rear of intake manifold, disconnect sensor pigtail harness connector from main wiring harness.
2. Place an ohmmeter across terminals B and C (SEE Image). Ohmmeter should be set to 1K-to-1OK scale for this test.
3. The meter reading should be open (infinite resistance). Replace sensor if a low resistance is indicated.

first question.. does the engine crank with the starter or not? the clutch-interlock disables the starter so thats an easy way to rule that out as a culprit. i'm thinkin CPS as well.
