== == A loose battery cable will allow the alternator to run 'open circuit'. This puts the engine computer and other equipment under alot of strain from having to deal with very poor quality power. (essentially pulsed dc with some high voltage spikes and varying with engine RPM) The battery greatly stabilizes this dirty power. Assuming you didn't fry your engine computer, I'd try just resetting it. Disconnect the negative battery cable. Wait 5 minutes. Hook it back up. Try to start it. Beware of doing this if you have an anti-theft radio or an ignition key with a chip in it. You'll likely end up needing the dealer. The harder the copper wire presses the more energy will flow through it.

Yes, cause a reduction of power to the engine. It will result in a power-train malfunction error

Yes, if the cable is cracked and swollen it has a high resistance thus causing a loss of current. Replace any cracked or swollen cable.

Hard to say. It may cause no damage at all and then again it might cause serious problems.

dead battery, or a bad ignition control module inside the distribureator.

if you have good battery and cable connections, the starter motor or starter relay is bad
