If it blows when trying to crank, the starter has failed.
I assume you mean the fuse keeps blowing? It's certainly possible for the lighter element itself to go bad as well as the socket you plug it into. Also, there are often other circuits that use the same fuse.
You have a ground wire that isn't grounded causing a shortage therefore blowing the fuse....I would start with the ground wire that is connected directly to the starter itself
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.
there is a fuse under the hood for "fuel ingtion system" # 20 amp change that im searching why my car keeps blowing the same fuse
There is an overcurrent situation in the circuit, could be a wire shorted to ground.
i have a 96 dodge avenger 2.5 and it keeps blowing my ignition switch. any idea why?
Check or replace the socket
Faulty tail lights - causing a short.
Failed pump, or wiring shorted to ground.
dont run it so hard dont run it so hard
You will need to replace your starter, this happened with my car a couple days ago, I brought it into the shop, got the starter replaced and the fuse does not blow anymore. It happens because the starter draws to many Amps of electricity due to age, amount of use etc.
