HELP...won't start....2003 F-150 Harley Davidson edition 5.4 lightning
 
So I'm not sure why my truck is trying to turn over but will not start. It's cranking like it's going to turn over but just keeps cranking... I can hear the fuel pump start up but it seems like no gas is getting through. I just had 2 new coils put on it because it was missing bad and I thought I threw a plug.... does this year have the Fuel Pump Drive Modual located by the spare tire bracket? Is there something else like a fuel filter, fuse or solenoid that should be checked? I hope someone out there will be able to help point me in the right direction! Thx

No FPDM. There is a Schrader valve on the fuel rail, connect a fuel pressure gauge to it, specs are 28 to 40 psi. Fuel filter is on the driver's side fuel rail, should be changed every 30k.
