Check the starter solenoid. Usually mounted on a fender well. Find by following the + battery cable.

check for clogged fuel filter first, usually the pump works or it dosen't, check and get back to me.

have fuel pump checked i have known a bad fuel pump shorting out causing pcm fuse to blow.

SOURCE: 2000 Crown Vic cranks but won't start.

Check the fuel pump reset switch again, if it is popped back out then replace that little switch in the trunk, any ford one will do. it works off a magnet and a bearing to close the circuit for the fuel pump. easy fix.

There is a resistor in the light control module under the driver side of the dash. You can replace the whole module which is about 100+ dollars or if you're good with soldering, replace the resistor. You will need to remove the box and open it up. Find out the resistor part number and replace it. This is a common problem on the 03-05 crown vics. Good luck
