Sounds like you shorted the alternator's power post to its case (ground). That likely sent a surge through the electrical system. You probably fried a fuse or damaged the ECU. Check all your fuses, especially any for the fuel pump and ECU. Even if they look good, swap them. The ECU might need to be checked or replaced. The cam and knock sensor codes are a symptom, not the cause.
Traced cam sensor wires back from sensor an pig tail found a burned up wire repaired it starts up fine an codes went away thanks for your help an I'm glad I found it
