Having problems with your 2003 Ford F150 Regular Cab ?
2003 F150 4x4 does not start after sitting about a week starter grinds and dome light and underhood lights flash (Fairly new battery and altenator). Truck does fine unless it sits for about a week, and will restart with a jump. Is this a relay problem? I can hear a relay in the cab clicking with the flashing lights
You may have a parasittic draw some were check for components staying on when ignition off, also check for a loose ground also the battery may have a bad cell and not holding charge
