I know its my fuel pump. But I'm looking for another option, anything else I can check. Changed my relay. I can hear the pump kick on and then shut off when i turn the key.

Pump initialization does not equal fuel pressure.

Check the fuel pressure at the rail with a gauge.

Go to harbor freight and get a cheap fuel pressure gauge.. maybe it's not your pump.

It's a pain to replace, but it could be worse...
