confirm that fuel pump is working,there's a fuse,and relay in the trunk next to fuse box.with a sethoscope you should hear fuel injjjectors clicking,if fuel pump is bad.If not its a bad sensor somewhere.

The fuel injector's not clicking. So does that mean there's a bad sensor somewhere?

yes,Open coffin box where computers are,make sure no ATF wicked into there,if so clean it up.alsosome have fuses to protect them.Check cranksensor in case its loose.I ran over sticks and it unplugged.Check coolant sensor for broken wires,or unplug,and jump connector with paperclip.

ok its probably fuel pump or fuse or relay.I think you can open relay,and force contacts to close to test
