2008 unlimited rubicon 3.8l, new long block, new exhaust with headers, new O2 sensors, new pcm, new camshaft position sensor and crankshaft position sensor, checked grounds, still throwing p0344, and I fixed one code another code pops up

Is it both positive and negative or is it just the negative side I did the little braided strap they run through their the ground that goes to the body and stuff and the motor I did take that off and I replace that with a regular battery cable and I've done that from the motor to the where the front or the battery cable hooks on to the body and then from there up to the negative post on the battery
The guy I bought this from said that he was driving it and it just died well in the beginning we thought it was just a timing chain until I pulled the motor open and it had dropped a valve seat and it went into three other cylinders so we knew that the motor was shelled and bought new long block
I think we need more information.
The P0344 code indicates a problem with the camshaft position sensor circuit, which could be occurring for a few reasons despite your new parts. Here are some suggestions you might want to consider:
Wiring and Connections: Double-check the wiring and connectors for the camshaft position sensor. Look for any frays, corrosion, or poor connections that could be affecting the signal.
Sensor Alignment: Make sure that the camshaft position sensor is properly aligned and installed. Sometimes, incorrect positioning can lead to sensor errors.
Camshaft Timing: Ensure that your camshaft timing is correct. If the timing is off, it could affect the readings from the sensor and trigger the code.
Diagnostic Scanner: If possible, use a professional-grade diagnostic scanner to check live data and see how the camshaft position sensor is behaving while the engine is running. This might give you more insight into what's going wrong.
Other Related Components: Sometimes issues can stem from related components. Verify the operation of the crankshaft position sensor as well, since they often work in conjunction.
Voltage Checks: Verify that the sensors are receiving the correct voltage as per manufacturer specifications.
Ground Issues: Although you mentioned that you checked the grounds, make sure that all grounds related to the engine and PCM are solid, as poor grounding can lead to inconsistent sensor readings.
It's frustrating when one fix leads to another code, but keep methodically working through it, and you'll likely find the issue! Good luck, and keep us posted on your progress!

When I first did the ground to make sure they were clean and everything there were three or a couple of them that were tore off so I welded a stainless steel ground strap to the frame and from the frame to the body and the body to the motor so all the grounds are perfectly good and that also is bolted on to the negative side of the battery
