I put gas in the car and started it. I went to mess with the heater/AC and once I pushed one of the buttons the car died out and wouldn't start back up. It will crank but not start like it isn't getting gas. Dropped the tank because I thought it was the fuel pump and it's not. I've checked all the fuses and relays and I have discovered that in my fuse box on the driver side about 90% of the fuses aren't getting power only the last column on the box and I'm stuck not knowing what it could be.

Hi,

Since we lost power at the interior fuse box, we need to work backward to see where power comes from.

If you look below, I attached three pics from the power distribution fuse box so you can see what is happening. I started at the AC power supply, pic 1. Note the supply powers other components within the same fuse box.

Power is received at the J connector, highlighted, so I worked back to see where that took me. See pic 2. Note the output (J) goes to the affected fuse box. Power to it goes through the ignition switch and is provided at circuit C.

I continued and found power is from the 60-amp maxi fuse in the left maxi fuse box under the hood. See pics 4 and 5 to locate the fuse.

Check that fuse. I suspect it will be bad. Let me know what you find or if you have other questions.

Take care,

Joe
