Ignition fuse location

Is power getting to the ignition switch? Do the warning lights and gauges come on when key is turned to on? That would verify power in and power out at the switch. Then you would need to check the start circuit. A single start wire comes out of the switch, the signal travels through the neutral safety switch and a starter relay and then to the starter solenoid mounted on the starter. Solenoid closes contacts so battery power can operate the starter. If new starter doesn't work, power has been lost between the ignition switch and the starter.
If no power to the ignition switch check maxi fuses, all fuses in fact, and possibly a fusible link from the battery that may be the feed for the switch.

Sounds like the Ignition switch wasn't the problem, check your fuse links at starter, they are soft fuseable wire that will burn if shorted or even when they get old over time they will go bad. they are the smaller like #10-12 ga. wire , should be at least 1 maybe 2 of them at harness connection to starter.

under nneath the hood of the car where the fuse,s are black looking fuse

The wires and the fusible links at the starter should be checked, and you will know a bad fusible link wire when you find one, because they will stretch like a rubber-band, and repair any fusible link wire that you find that are burned out.

If you can not find any problem with the wiring or fusible links at the starter, then check the "start" fuse for the starter field wire, (if it has one it will usually be located out in the fuse/relay junction box) also the starter field wire should be connected to the "S" terminal on the starter solenoid and it will be "hot" or have power to it only when the key is in the "start" position, and if the field wire to the starter is the wire that burned up then the ignition switch itself might have been damaged.

Check your fuse, look for broken ignition wire, test your ignition switch.

Check and make sure you are getting power to the ignition switch and to the stator wire on the starter. Turn the key on and and measure the volts going to the starter on both wires. You should a atleast 12 volts going to the stator wire and to the main wire from the battery. If you are not getting power there it could be a fuseable link in the power wire from the ignition. I noticed that you replaced the ignition switch make sure the rod from the key switch has not come out of the switch.

Thank You for contacting Fixya.com

look for a 5 amp fuse, crank fuse in car, not under hood

DOES THE CAR SOUND LIKE IT WANTS TO TURN OVER AT ALL?

Why are you having to jump it? Bad battery...too weak....weak battery not supplying enough juice to the starter to turn the motor over....
