HYUNDAI SONATA FUEL PUMP PROBLEM

2004 Hyundai Sonata • 124,000 miles

The engines turns over. I have no power to the fuel pump. The exciter wires to the fuel pump relay are not powering the relay where should I go from here?

Check ignition coil fuse, engine main relay and computer

Found a blown fuse so now I have spark. I m still not getting a signal from the ecu to the fuel pump relay. Also I tried bypassing the relay and the fuel pump would not turn on. Any direction would be greatly appreciated! Thank you.

Power the fuel pump from the battery at the FP wiring connector -if it turns on-backtrack back to the computer fuel pump control relay circuit-relay is good the problem is coming from the PCM
