Yes, if the cold cranking amps are low it will give a hard time to start. Also make sure the battery terminals are tight and free of corrosion. While the vehicle is running, check the charging system with your meter, it should read between 13.5 to 14.5 volts. If any other voltage the alternator is no good.

I checked the reading while it was running and got a reading of 13.8. I figured I had left something on but when it happened again today and I was sure that I did not leave anything on it left me wondering. Had Napa test the battery and alternator but the only thing he mentioned was the CCA but then said the battery was good which confused me. Then it started up with zero issue tonight. I just wanted to make sure that a bad crankshaft or camshaft would not mimic battery issues like dome lights, headlights, radio and such not working

No it would not cause that.

Thank goodness! So more than likely I am dealing with a battery issue due to the CCA then? One more question would low CCA cause issue with jumping starting the JeepI guess what I am trying to ask is if low CCA would allow the vehicle to start up sometimes, then not start up and even cause the vehicle to just die while running?

Yes, also if you have a bad cell in the battery it would give a hard time to jump start.

Ok, thank you. I feel much better now. I did not want to waste money on a battery if it was not the issue. Thanks again for answering my questions. I really appreciate your time.

I have been having with my Jeep not starting. A friend tried to jump start it but nothing would happen. The dome light worked however the horn did not. Tried a different vehicle and jumper cables and the Jeep cranked. Ran fine the rest of the day and the next day. This morning my Jeep started fine. I drove to the gas station, came back out and it would not start. Had the same issues trying to jump start it. Napa Auto Parts walked over and tested the battery which read 12.6 volts, the Napa guy was able to start my Jeep with a jumper box. He said the alternator was good too. When leaving to drive my Jeep home, several lights in the dash were flashing, the radio would not work and the speedometer would not work. Got home and let the my Jeep run idle for 20 minutes, then it just died. The Jeep set for several hours while I was at work. I got home and tested the battery with a multimeter and it read 12.6 volts. Tried starting it and it would not do anything. Four hours later, I wanted to go outside to see if my headlights were working turned them on and they were. I thought let me try and start it. The Jeep started right up with no issue. Could this be a bad battery even though it is showing 12.6 volts, the Napa guy did say the CCA were low but the battery was good. Would a faulty crankshaft cause issue that would mimic a bad battery, alternator or starter? I'm at a loss and don't want to waste money buying a battery if it is something else.
