Anyone ever have this code show up? Ive read the other posts on this code, but they relate to older models. When my gas tank is empty, I open the cap to fill up the truck and when I try to start it back up it takes about five cranks before it will start. Any help or suggestion is greatly appreciated.

 

The problem is in fuel delivery. Your not getting enough fuel. When was the last time your fuel filter was changed? I got a CEL once and diagnostic reported it was insufficient fuel flow, which in turn was the fuel filter.

Which reminds me, its time to change mine.

 

Thanks Darren, I appreciate your help. I just bought the truck so Im not sure when it was changed last, but the guy I bought it from had ford service done on the recommended intervals. He gave me a few of the documents but none noted the fuel filter change.

 

P1450 - Unable to Bleed Up Fuel Tank Vacuum

DESCRIPTION - Monitors the fuel vapor vacuum and pressure in the fuel tank. System failure occurs when the EVAP running loss monitor detects excessive fuel tank vacuum with the engine running (but not at idle).

POSSIBLE CAUSES - Blockages or kinks in the EVAP canister tube or EVAP canister purge outlet tube (between the fuel tank, EVAP the canister purge valve and the EVAP canister)
Fuel filler cap stuck closed (no vacuum relief)
Contaminated fuel vapor elbow on the EVAP canister
Restricted EVAP canister
CV solenoid stuck open (partially or fully)
Plugged CV solenoid filter
EVAP canister purge valve stuck open
VREF circuit open (harness near FTP sensor, FTP sensor or PCM)
Damaged FTP sensor

 

Problem fixed. EVAP canister purge valve stuck open. Bought a new one and starts great.
