fuel pump not working pulled over at store and wouldn’t start

Hello,

The reason your vehicle keeps blowing this fuse is that you have a short to ground somewhere in the circuit that this fuse protects. Also, you should never replace a blown fuse with one that has a higher amp rating. The original fuse was put in place to protect whatever the load is for that circuit. If you replace a 15A fuse with a 30A fuse you could be allowing excess current to reach the device the 15A fuse was protecting, frying it.
A short to ground works like this. The neat thing about automobile electrical circuits is that according to Ohm's law is one of the three electrical properties remains constant, than when one of the others rises the other must fall. What am I talking about. The constant in this equation is voltage, or the force of the electricity. Your car battery supplies a nice constant 12.6 volts. So if you have a bare wire that is grounding out on the car frame, and not allowing all available voltage to be dropped across the circuit's load, resistance, or anything that opposes the electrical flow, goes down, meaning that current (amps) must go up. The current, or flow, of the electricity will continue to rise until it surpasses the rating of the fuse on the circuit and, pop, blows the fuse.
So, in the diagrams below I have given you the diagrams for the under hood fuse box and the Power Distribution Wiring Diagrams for your vehicle. Follow the circuit from the blown fuse and find the wire that is shorting to ground from the information below. Please get back to us with what you find out.

Thanks,
