car will not start and I only hear one firm click
i had to removed battery and case to replace spark plugs. I had battery checked and recharged. it came out good. turn the key to start and only get one loud click. help!
I suspect that you have an open circuit to the starter since you removed the battery and removed terminals from battery post. Check the connections at the positive terminal carefully. The loud click you hear might be coming from the starter solenoid and if there is no battery voltage in the big wire that goes to the starter (check it at the starter with a test light) then that confirms an open circuit out of the positive battery terminal.
