Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, when does it blow? how often, what are you doing when it blows, Does any other fuse blow?
doe not blow in RUN just when you turn to crank? can you ever get engine to crank?
98% you have a bad starter, 2% possible starter relay, No way for me to say which, relay is easiest to try,, if still blows? the Ign 30 fuse send power to the starter relay then to the starter, It is most likley you have a shorted starter motor, Here are 2 links, one for relay location one for starter
change the relay, if fuse still blows, starter is bad
unplugged what? what wire?
all I can add? the fuse powers to ignition switch, then to starter relay then to starter, if relay out and fuse still blows? then you could? have bad ignition switch, rare but possible, if fuse blows with purple wire off starter and relay IN? then a wiring short from relay to starter on purple wire, Never s een that but possible, This all is ONLY if fuse blows in CRANK and not RUN position which you said yes
here is wiring diagram
I sent the reply to this as other possible. You said ONLy blows in Crank so, with new relay, starter unplugged and still blows,. you could have a shorted purple wire from relay to starter OR possible ignition switch, I am not there so can only list possibles and i attached a wiring diagram. Does it blow with relay removed? you have not supplied that info
then short between relay and starter so, if you need to get running till looked at on the purple wire from relay to starter, turn key on with relay OUT, jump 12 volts to the terminal you unplugged at the starter, engine should crank and run
