I think that model also has an inertia switch. if that fails, you wont have spark or power to the fuel pump. the switch on some models is down on the passenger side, right above the carpet line. you may have to ask an expert on the location, but i would check it for sure. had a similar problem on a ford ranger. also, check the ecm relay.

It is the relay for the main computer.
If you spray gasoline or WD-40 into your fuel injector while cranking the motor, if it starts and begins to run it is your fuel delivery most certainly.
