Car won't turn over. Camshaft sensor went out so I replaced it. It was plug and play so I'm not sure what happened/ is wrong. About 2-3 weeks before Christmas I installed a 250 amp high output alternator and redid my power to battery and all ground wires with 1/0 ofc wire. Other than those two I replaced and primed fuel pump when I changed the sensor. It ran fine up until the camshaft sensor went out and replaced. All codes are low voltage?? Will post full VCDS report shortly

If you had the battery disconnected for any amount of time, it will set fail codes. If the item is not on when you run VCDS, it will set a no or low power fail code (E.g. Radio isn’t on, SAT radio isn’t on you will get fail… if you removed the OEM radio, you will always get a fail for audio system components, etc.)
Save the codes and clear them all. After that run VCDS scan and repost your result.
