Normally you would check for spark at the plugs and then work back from there.
The battery, alternator, and starter would be ok if it cranks.
If the plugs have spark, the next thing to check is fuel at the injectors. If there is no spark at the plugs, it could be a crank or cam sensor.
A mechanic would use a scanner to check those and other components.
SOURCE: where is air conditioner recharge port
remember you will always charge an air conditioner on the low side. which is always on the larger hose. there is a smaller one which is the high side so stay away from the small one.. look up near the radiator and see if you see the dryer which is about 3 inches across and 8 inches long and looks like a cylinder.. on this device there is a port where you can charge it .. also this year might be up near the firewall .. they change locations too often .. thanks and holler if you need more.

It could be a clogged fuel filter or a bad fuel pump. Also try replacing the spark plugs and spark plug wires and having the timing checked. Good luck.
