My Jeep has been starting fine when cold but when it warms up and I stop and try to restart it it will turn over fine but won't fire and if I wait an hour or so to let it cool down it will fire up again fine. I checked the codes and came up with 12, 54, and 55 with the 54 being "No camshaft signal detected during engine cranking". I installed new plugs, wires, distributor cap/rotor and a new coil. I also checked for spark at the coil when it won't start and found no spark. Then I checked the primary wires going into the coil and found normal readings. I called the parts stores for a cam position sensor and they all say they can't find one in their system. Has anybody had a similar issue? Thanks for your help!!
 
12 would be camshaft sencer...timing over-retard
54 and 55 are the o2 sencers notworking properly because of the timing

possiable fix...timing chain or timing chain tensoiner

or electronic spark control module
