Electrical problem
2004 Hyundai Santa Fe 4 cyl Two Wheel Drive Automatic 72000 miles

My 2004 Hyundai Santa Fe won't start. The relay for the fuel pump isn't getting power but it can be bypassed and the fuel pump starts right up. When I try to start the vehicle after bypassing the relay it still won't start. I have also checked the inertia switch and it hasn't popped up. It has gotten regular fluid changes and has always run like a champ before. I'm stumped as to what it could be.

Could be the computer not grounding the fuel pump relay

How do I check the computer to see if that is it? Or would it be better just to reset the computer? If I do have to reset the computer how do I do that.

Would the relay also cause the spark plugs to not fire? If not what would cause it because they aren't working even if I bypass the relay.
