1996 Buick Skylark car will not trun over

If your saying the starter motor won't crank, have to check starter wiring circuits. Mainly two circuits to check, one is battery voltage, hot all the time. The other circuit goes hot with key in the crank position and is wired through the neutral switch. Any testing at the starter, make sure tranny is in park or neutral and the parking brake is set.

Your battery has a full charge and battery connections all good?

If your saying it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs, if spark everywhere, use a gage and check proper fuel pressure. Also check fuel injector pulse, engine cranking.
