99 Camry no crank no start

Hi, I have a 99 Camry with the 2.2L. that has a no crank no start and am looking for some guidance. I went out to start it one afternoon after driving it top the store and it didn't crank or start. All other power is fine (lights, radio etc..) I checked all the fuses and relay's and found the 5amp fuse in the dash was blown so I replaced it. When I tried to restart the car that fuse blew again.

I have checked the battery - it's at 12.6v. Checked the constant power from the battery to the starter, it's at 12.6v at the starter. I also pulled the starter and had it checked at my local AutoZone, no problems with it. I have replaced the ignition switch, starter relay and the neutral safety switch. I also had to replace the main negative battery ground wire since it was a little frayed. None of these have helped and am still having the same issue. The starter engages for about 1/2 a second when I try starting it, then the 5amp fuse blows.

I can get the car to start by replacing the 5amp fuse in the dash, pulling the starter relay, turning the ignition key to on then jumping the starter relay points 3 and 5.

I'm now trying to find out why that 5amp keeps blowing. Any help would be appreciated!!
Thanks!!

ENGINE COMPARTMENT FUSE BLOCK: 5A

The (5 Amp) ALT-S fuse protects the Alternator Charging Circuit:

Specifically, the ALT-S fuse enables the voltage regulator to monitor battery voltage, playing a part in regulating the alternator's output and ensuring optimal charging.

If the ALT-S fuse blows or has poor contact due to corrosion or damage, it can disrupt the voltage regulator's ability to sense battery voltage, potentially leading to charging problems and a "Check Charging System" warning light.

Inspect the ALT-S fuse and its connections, along with other components like the alternator, battery, belt, wiring harness, and the voltage regulator itself.


DASHBOARD FUSE BLOCK: 5A

IGN 5 A: Gauges and meters, charging system, SRS airbag system, seat belt pretensioners, multiport fuel injection system/sequential multiport fuel injection system. This is a fairly common fault and it usually involves the fuel injectors/FI wiring harness and/or FI connectors. Manipulate the injector harness gently while a helper tries starting the engine. If it catches and starts, repair the damaged fuel injection harness. Also use a strong flashlight and inspect for chaffing anywhere along the fuel injector wiring harness, especially for where it might be rubbing against the engine or firewall as it transitions around a corner radius.

Check the dashboard MIL light and see if it's illuminated - if it is, retrieve any OBD2 error codes and report them here.
