SOURCE: jeep wount start
When you turn the key on all the lights come on normally? and when you try to start you lose the lights and hear a click? If so the battery cables are loose, or broken. If thats not the case it could be a relay or stuck starter or switch. You can try a screwdriver at the starter hit the little wire and the big wire it will spark and should turn the engine over "MAKE SURE IT IS IN PARK WITH THE BRAKE SET" do this last, if you do all that and it turns over you can say the starter and cables are good. Next replace relay and try, still nothing get a new switch. Hope this helps.

Since you've replaced many of the usual suspects (fuel pump etc.) you might want to look into testing or simply replacing the crankshaft position sensor or the camshaft position sensor. If you intermittently lose one the these signals it would cause the problem you describe.

That code PO455 is indicating that you have a fuel vapor leak somewhere in the system. I'd check from purge canister back taking a close look at all the vapor hose to the tank. If all that check out, purge solenoid & canister would be my next area to check. That's probably what your smelling , so it might be easier than you think to sniff out the source.

Disconnect and replace fuel filter.With filter disconnected have someone momentarily turn key to on position to see is fuel pump is working.Make sure you have lots of rags,a drain pan and safety goggles on
