Fuel system could be over-pressurising. A fuel pressure test would be advisable. If too high replace the pressure regulator and/or check the return line to the fuel tank.

Have you tried draining the water from your water separator? It's on top of the engine and those are partly yellow, if I remember right. It has a valve to open and drain water into a small bowl or something that will fit in there. This is particularly important in cold weather. The water can freeze and will Crack the plastic.

Evap emmission,control sys leak


Do not top off your gas tank. The gas is going into carbon canister which is only for fuel vapors to go into (carbon canister opening near the top of fuel neck near the gas cap). Your flooding the fuel vapor canister with liquid fuel; of course you are going to get a sensor message... 'Evap emmission,control sys leak

P0443 The fuel vapor canister reduces that gas smell on hot days outside/inside of car. The fuel vapor canister fillers bad smells from gas tank on hot days when the gas expands and burps fumes through carbon canister filter. From the canister (gas vapor fumes) goes back into the engine to be burned again...it's a closed loop for vapors to be recycled though engine. Don't worry, once the carbon canister dries out and no longer flooded with raw fuel the code should go away...just don't let the top off fuel tank back flow into the 'Evap emission control' carbon filter near the top and close to the gas cap...:)

Code po456 on my 2006 mustang 6 cyl. is there an easy fix


This elaborates more on the code.
P0456 - Evaporative Emission System Leak Detected (Very Small Leak)
Description:
The powertrain control module (PCM) monitors the complete evaporative emission (EVAP) control system for the presence of a very small fuel vapor leak. The system failure occurs when a fuel vapor leak from an opening as small as 0.508 mm (0.020 inch) is detected by the EVAP running loss monitor test.
Possible Causes:
• Very small holes or cuts in the fuel vapor hoses/tubes
• Loose fuel vapor hose/tube connections to the EVAP system components
• EVAP system component seals leaking. See the Possible Causes for DTC P0442
Diagnostic Aids:
Check for a missing fuel filler cap or the integrity of the cap.
Check for loose or damaged vapor hoses. Visually inspect the EVAP canister inlet port, CV solenoid filter, and canister vent hose assembly for contamination or debris.

I have an 1987 F-150. I have replaced the plugs, wires, distributor cap, and rotor. Still sputters and has a lack of power. Any suggestions?


Sounds like a plugged fuel filter or filters, you may have two filters, one is the can shaped filter on the front inside frame rail drivers side, about the size of a coke can, the other is a black plastic canister back towards the tank, some early 1987's still had a paper filter inside the screw off bottom of the canister, they plugged really easy. Check both.

Service engine soon light came on, replaced gas cap it went off but a week later it came back on, when it try to fuel the truck it spill the gas back out like it is a full tank


One of the most common causes, is blockage in the venting system from fuel entering the vent lines and into the charcoal canister, the fuel gets absorbed by the charcoal canister causing it to swell and block vent lines. the gas tank contains both fuel and air. when you fill it up the gas displaces the air and the air has to go somewhere. but the air that is displaced is full of gas vapor so the gas vapor goes to the vent lines and into the charcoal canister, when the charcoal canister swells up it prevents the air from escaping the tank, canister could be clogged,canister filter may need replacement,electrical connection to the close valve may be open,canisterf might be damaged,purge valve from canister might be clogged,vent hoses might be clogged, the vent hose could be clogged, or the vent hose may have a kink. all this is caused by overfilling the gas tank, getting that last drop of gas in the neck of the fill tube.
good luck!

First make sure you have the filter cap ( located along frame rail on properly ,they can be a bit tricky, and if not will **** air) then remove filler cap located on top of engine, with off turn key run position ,BUT do not start and obseve fuel bowl to see if it fills with fuel, if it does put cap back on. NOW turn key to run position for a sec. or 2 then back off, REPEAT this 2 or 3 times then try to start. GOOD LUCK

05 f-250 will not start


I sometimes get an air lock. Loosen the cap on the filter housing on top of the engine. You may hear a hissing noise that sounds like air escaping. When you have the cap off turn the key on for a few seconds.( DO NOT CRANK THE ENGINE) This will fill the fuel bowl. Put the lid back on and try to start again. You may have to do this a couple times but it does get air locked at times. Wash off the excess fuel that may splash out before starting the engine.
