    2007 XLT EL. Died shortly after filling up with gas. Would not restart. Didn't have any tools on hand, but had fuel pressure at the rail (pressed the schrader). Had my scanner, but there are Zero codes.

    What the hell?

    Gasoline engines need 3 things to run: Air, Fuel and Spark
    It's not air - we're still breathing
    Fuel depends on the amount of pressure in the line
    Spark - kill power to the pcm and no spark

    Check all fuses for the pcm with a meter or test light

    Is the theft light blinking fast or slow?

    Went back with my fuel gauge. Pressure was good. It started right up. I let it idle for 5-10 minutes, no problem. Revved it to 2500 rpm, let off, and it died. Wouldn't restart again.

    Its at a McDs parking lot so im not going to be out there for hours working on it. Getting towed in the morning

    What pressure is "good"?
    It is similar to when you go to the doctor. They check how many beats per minute your heart pumps, not if it is pumping.

    What kind of scanner are you using?

    I'm interested to hear the outcome of this situation. When mine did this it was the fuel pump. Came out of the house one morning to go to work and it was all crank and no fire. Used the programmer for my Mustang to scan for codes, none found (although if I'd tried to start it enough times I might have found one eventually).

    I had one like this. Navigator quit, no codes, no start even with starting fluid.

    Changed crankshaft sensor, no more problems 2+ years.

    The shop I had it towed to said they diagnosed it as the crank sensor. So we will see if thats what fixes it, but I'm guessing probably what it is. It sucks that it wouldn't throw a code otherwise its a fairly simple repair.

    The really strange part is that it happened right after I filled up with gas, so that usually make you think it was something in the gas
