Truck 2000 f250 wont staet when the outside temp is high…

Customer Question
Truck 2000 f250 wont...

Truck 2000 f250 wont staet when the outside temp is high after it's been running just fine. If it's 70 deg or cooler outside it starts right up after driving around. always runs great until you turn it off, pleanty of power idles perfect every is good but when outside temp is 90 deg or higher and you've been driving for awhile running great once you turn it off it will not start. truns over just fine, something is telling gaspump to shut off and the brake peddle stiffens up. once truck has cooled down and outside temp is below 70 deg it starts right up like nothing was ever wrong. it could be 105 outside and you would never think you have a problem by the way the truck runs but dont turn it off.

Mechanic's Assistant: Has the vehicle turned into a gas hog? And how does it start -- same as usual?

Gas mile is about 11 miles to gal city driving 16 hwy and thats been the same for a very long time now.

Mechanic's Assistant: Are you fixing your F250 yourself? What have you tried so far?

When its hot outside and wont start, engine is conpletly cold i'll switch relays around and then it will start again. only when truck is completly cold though.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Something is telling the gas pump to stay shut off. it's a lack of gas that it wont start, doesnt matter if tank is full or almost empty it's always outside temp that affects it.

Engine never stalls, it runs like a champ until you turn it off. No engine light and nothing comes up when you plug it into test machine. It starts for just a second this is the residiagal fuel but once it's gone thats it. It can turn over and over and over again but will not start until it cools down outside and then it starts like nothing was ever wrong. SOMETHING IS TELLING THE FUEL PUMP TO STAY OFF. Please beleave what i'm telling you.
