2003 V6 Won’t Start

Hi all, I have an issue where my truck wont start if I try to start soon after shutting it off. Doesn’t matter if I drive it around the block or for an hour, it will start up just fine for the trip and then no crank if I shut off and attempt to re start within a short amount of time after turning truck off. The panel lights up but there is no crank at all, I do hear one click under the hood when I turn the key. If it sits for several hours, it will crank up and start fine. I did replace the battery, now suspecting a fuel pressure issue. 2003 F 150 V6 manual transmission with 220 K miles. Any ideas or help is appreciated.

With no crank it's not fuel pressure or anything related to fuel.

Something electrical. You replaced the battery. How are the cables, connections, grounds, solenoid and switches?

Not clear if you're using the word crank correctly. "No crank" would have nothing at all to do with a bad fuel pump, as stated above. "Crank" means the starter spins the engine. Sometimes people confuse crank with fire or start.

If the click is happening when you turn the key to Start that would more likely be bad electrical connections, or a bad starter relay (on the firewall), or a bad starter. The click, if it happens at Start, sounds like a bad starter relay.

Below, not mine, borrowed it from the internet, but it looks like this. There's an electrical contact inside that can stop working.

One click, usually means a bad starter
multiple clicks usually means bad starter relay/solenoid
no clicks, (nothing) usually means bad battery or battery connections are bad
