There is no fuel reset button. What kind of testing have you done? Engine cranking, did you check for spark at the spark plugs? Is there a fuel injector pulse? Any applicable trouble codes?
If your missing everything, I'd check the cam and crank sensors.
If you have narrowed it down to only the fuel system, we can go that way.
Do you hear the fuel pump coming on normally comes on for approx 10 sec. when you turn key on, if no pump noise fault is still in fuel system, check the fuse and wiring, check for trouble codes, check injectors, etc

You will need at least a 12 volt test light to check the cam and crankshaft sensors. If either one is bad, the auto shut down relay will not ground the PCM. Remove the 4 pin electrical connector from the coil. one of the terminals is a 5 volt feed. Connect the light to that terminal and clip the other to ground. Turn the key to the on position. the light should flash once. If it does not flash the problem is in the ASD relay or its circuit. If it flashes once, try to start the engine. (don't worry, it can't start.) See if the light flashes during cranking or not. If not, return the key to off and then disconnect the crank sensor wire connector and try again. If it flashes as you crank the engine now, then the crank sensor is bad. If it does not flash during cranking then the cam sensor is probably bad. They are both easy to access and replace. The PCM could also be bad, but the cam/crank sensors are a more common problem. A repair manual is a cheap investment and could be helpful. Good luck.
Could be any number of things. One of the cam or crank sensors, the engine computer, a relay, and so on.
If you get a shop manual you will have the test procedure to find out what the problem is. I would also check for trouble codes in the engine computer.
I assume you checked the fuel pressure and it is normal. Are the spark plugs getting spark when it fails to start ? Are you getting injector pulse from the computer ? Any trouble codes stored in the computer ?
p1391 is intermitant loss of signal from crank sensor and cam sensor--change sensors!! change cam sensor first. good luck!! then try it, if still same way. change crank sensor.
