So does it crank no start or no crank no start?

The car does not crank only thing I hear now is a metallic clatter sounds like it may be coming from the starter but before I took off the pos it only sounded like a low battery and would start if I charged it

Either you have a bad battery and connections or starter motor-

If the starter is inop I would make sure the battery cables are clean and tight. Also make sure the battery tests good and is fully charged.

The battery tests good, I was wondering if there is a way to see if the computer is working without a tester obd2 it seemed to be an alternator problem(as it sounded funny) I think I damaged something as the problem seems totally different now

Have you checked all the fuses?A obd2 code reader would be nice to see if it linked to the ecm.
