my ac pump kicks on and off no matter what the rpms are at. the ac comes out warm and when i try to charge it the pressure goes up to overcharged and then goes to 0 because it kicks off every 10 seconds.

Welcome to AF, you cannot just charge the system without knowing what is in there start with, it should be evacuated, leak tested and properly recharged.

If the cel light is on there is a code, now the code reader may not work because the cigar liter/courtesy lite fuse operates the power to the scanner. You cannot evac the a/c without the proper equipment and backround.
