What are engine firing order for a 2010 jeep wrangler sport

SOURCE: my 2002 jeep wrangler sport

Have you taken it to your mechanic to run the diagnostics... I had the same issue and it turned out to be a vapor lock issue that required a gas tank gasket replaced.

did you check voltage to sensors if you need help with proedure, contact me, or you may try patrs houses on line in how to section.

Crank position sensor has a higher failure rate than it should...however i would not change it "at random" Check for continuity between b&c terminals of the sensor with a digital ohmeter.
There should be no continuity between them (b&c should be marked on connector) No continuity reading is same as when probes are not connected to each other.
I really dislike when people try and help and use terms that owners can't understand ... "check your zxy and qtr then add an abc" dosen't seem helpful. I hope I am as clear as I can be!!!
Good luck.

To avoid confusion, tag and remove the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes to reflect how your engine is wired.
