chains

My truck has been acting funny by stalling for a millisecond when making a sharp left turn. When to start it today and truck wouldn't start. Checked and found fuze burnt on one leg of fuel pump relay. Changed to new fuze fired right up. The only thing I have done recently was wire in red led lights into my rear tag light which should not have affected anything. Is there a possibility when moving wires around under truck to find hot wire I moved the harness that goes to the fuel pump and it has a s rape in it that shorted out.

Anyone had this issue let me know.

Thanks
