Car won't even crank...
Ok, if you are getting it solidly jumpered, and the starter does not "chatter", or "thunk in"
you are down to
not enough battery, IE too old, discharged, otherwise defective
Bad cable from the relay to the starter
Bad starter
(Remember that "new" parts do not mean "functional" parts)
Next, I'd take a screwdriver and short across the two starter posts right at the starter the same way you did the relay.
If it won't crank now, you are getting to the point of needing more test equipment. The reason is, it can be a "trick" to tell if
The battery is bad
or the starter is bad and drawing too much current, making it SEEM like the battery is down
The only real way to start down this road is to make sure the battery is charged, and find someone who can "load test" the battery with a "carbon pile" tester like this:
A person who knows how to use one of these can ALSO test the starter current draw with one of these, but of course you have to be able to get the car to the tester/ or the tester to the car.
So you could do "half" of it, which would be to charge the battery and haul the battery somewhere that can load test it for you.
Once you know the battery is good, we can work around that.
