Fuel pump issues

I have a 09 f150 xlt 5.4 180,xxx here recently i have had the truck not start twice. I changed the fuel pump relay thinking that was it and then today it did it again so I pulled the relay and put it back and it fired right up. Not sure if it is fpdm or fuel pump. HELP!

FPDM is a lot easier to change.

Do you know for sure there is no fuel pressure when it doesn't start?

no I do not. When it doesn’t start I just pull the relay and put it back and cranks up

Can you hear the fuel pump prime when you turn the key on? If not, before pulling the relay, turn the key off and back on till you do hear the pump prime.

okay. When it does it again I will try that. But it’s not throwing codes either
