my daughters explorer started running rough and chundered so she pulled it over..i went and got it and on the way home it wanted to die at stops and run rough, unless i kept a foot on the gas. then every once and a while, it would start running fine for short periods and the cel would go out. i replaced the fuel pump, relay and filter a year ago. i also replaced the lower intake man gasket (coolent leak) a few weeks ago, but it ran fine after. i see by the alt guage, it is on the high side of normal, almost over. i replaced the fuel filter again just to make sure as she runs it low on fuel and put in good fuel and seafoam. i did a koeo test with a jumper this morning and got codes (122) tps sensor voltage, (513) internal voltage fail in pcm, (565) canister purge circuit fail, (556) primary fuel pump fail and a koeo code of (998) hard fault. i hooked up a fuel pressure guage and with the koeo the fuel pump and relay work and i get almost 40lbs of pressure, i repeated this several times and always after starting it kept the pressure. i can smell a 'raw' or unburned fuel smell but see no drips or leaks. my daughter says she always smells this and goes through a lot of fuel. the oil also has the faint smell of this..any clues to start my trouble shooting would be greatly appreciated. thanks,
