Disconnect the wire at the starter and try the ignition. My guess is that the starter itself is the problem. If the fuse does not blow then it is the starter, if it does blow then go to the relay center in the engine compartment and check the starter relay. Work your way back to the ignition switch.
Dead short to ground or an overload
Short in the wiring or the starter is defective.
You have a short circuit/over current problem with the circuit. If the wires are not touching metal, then the starter may have failed.
Remove starter and have it tested for drag, load and shorts
could the pcm fuse be blowing because of a short in the air conditioning switch I have seen the starter be the cause of a blown pcm fuse.
Unhook the wires on the starter, replace the fuse, turn the ingnition key on as if you were going to start the car. If the fuse does not blow, it is your starter. I just had this problem with a 1996 Dodge Stratus. I replaced the stater and it now works.
A short.
Over current or short to ground.
There may be a short somewhere in the system.
Faulty tail lights - causing a short.
A short in the wiring (grounding out)
When a fuse blows there is a current draw caused by a short circut. I would check all my wires to and from the starter. More than likely there is a worn wire which is touching something metal and creating the ground.
