It could be fuel related. You need to narrow down the possibilities. First check to see if the fuel pump is working. You usually can hear them if you open the gas cap and have someone turn the key to the run position. As a second test you could spay a small amount of engine starting spray into the air intake and see if it fires on that.
If you do not hear it try this guide to test the pump.
On your vehicle you should see thirty eight pounds of pressure at idle, and if you remove the regulator vacuum line the pressure should rise to close to fifty psi.
