Does it turn over? If yes, then check fuel relay. If not, check starter relay.

Do you hear the pumps kick on? If you arent sure, remove the gas cap and listen for buzzing. If not, check the fuel pump relay (green). Even if it clicks on, it might still be no good. With the key on, check to make sure that the same voltage going in is the same voltage leaving it.

If thats not the case and the connector looks OK, get a new relay.
