Keep it simple. Two things to always check on these cars or any car is fuel and spark. Cycle the key (key on engine off position) you should hear the fuel pump cycle. If u don't hear the pump pull the rear seat out to access fuel pump on pass. side and check for power with a test light. No power: check fuses.
Power: bad pump. To check for spark use a spark tester or an old spark plug. Pull a spark plug wire off of any plug, plug in your spark tester or spark plug and ground the tester or plug to the block on an accessible bolt anywhere on the engine. Have a friend crank the engine while u watch to see if there is any spark. If u have spark and fuel then u can diagnose further but until then stick to the
basics first. No need for a mechanic u got plenty here to help.
