check and see if you have fuel pressure when it won't start... your pump might be going bad. mine did it... smelled like gas... but there wasn't any fuel pressure. just take the plastic off the nipple on the fuel rail and use something to press on it and see if it squirts gas out.

you can try and unplug the wire connector that goes to the tps (not the one from the tps to the trans... unplug the square one) i had a bad tps and unplugged this and it runs well enough for you to drive around

got it fixed. ignition coil, tps, plugs and wires
