I have a 2013 JKU That has a crank no start with multiple camshaft position sensor codes 4 total one generic 2 pertaining to bank 2 and 1 pertaining to bank 1. I have tested the voltage at the plugs and seems to be reading what it is supposed to. Has spark I can hear fuel pump turn on. I am confused. Anyone have similar experience.
thanks for looking.

 

You won't like my answer. My 2014 JK had a crank but no start condition at about 55,000 miles. The cause was a broken exhaust valve spring inside the engine. I still have the spring at my desk at work. It simply looks like a latent, random defect allowed the spring to break.

 

Well that is not encouraging information... did you have any active codes?

I don't remember if I had any codes. However, I do remember trying a crank position sensor first, so I may have gotten a code for that. It did not fix the problem. I do 95% of my own maintenance, but when the simple things failed I had it towed to an independent shop who found the broken spring.

 

Now not getting any voltage to fuel injectors.
hmm
