Fuse are clear plastic so it can be check visually. If the wire in the fuse isn't broken/burnt it is good. Better yet you can use a multi-meter or test light to check the fuse and for power without removing the fuse. If you have power on both sides of the fuse the fuse is good.
Generally it's a bad connection or fuse isn't insert well.
could be the blower motor, a fuse, or a bad wire.
locate fusebox, probably under drivers side dash, find bad fuse, remove it, put new one in,
you check the middle of it and if it is black or the little wire is broken it is bad or just use a fuse checker and if the light doesn't turn on it is bad Call the parts guy at your nearest dealer
prob a bad fuse or switch.
Look at it closely to see if it is blown. If you cannot tell by looking then check it with an ohm meter.
Fuel pressure test. Of course if it is not running, fuse and relay are good then it is bad.
Remove starter and bench test it for operation and current draw
maybe that or a bad alarm fuse
Usually if you look between the two metal ends there is a glass tube, in the tube is a metal wire, it can be of various size, if this wire is broke, burned or not visable the fuse is blown or bad.
Circuit breakers are difficult as there is not an otside way to tell if they are bad. The plastic blade type fuses are easy pull out the offending one and look through the plastic at the top to see if the wire is broke or not. If it has a space in the wire the fuse is bad.
it is a fuse that protects the ignition relay from too much current. a bad fuse would cause a no start, and if you pull the fuse, its center core will be burnt out if it is bad.
