My jeep died again today while roaming around town. I checked the codes when it died and I got: 54* No fuel sync (camshaft signal) detected during engine cranking and 27* Injector #12345 or 6 output driver does not respond properly to the control signal.

I found another resource that says 54 = change the distributor sync sensor. I was trying to find the part on the web and it's non existent. Do I have to change the whole distributor or something?

Also I reset the comp and it started right up. Weird?

 

After further reading I understand this is the cam position sensor. Can I replace the sensor or do I have to replace the whole distributor? And would it cause this problem with only dieing when I'm driving in the city not on the highway?

 

No you can replace just the sensor. You will have to remove the distributor and disassemble it to get to the sensor though.
