I'm having the problem where my jeep just shut off or won't want to start. It will turn over it just won't start. I tested my fuel pressure yesterday and the fuel pressure is where it should be w/ and w/out the fuel regulator vacuum atached, 31-40 PSI and 41-49 PSI. The Haynes manual said that when I turn the jeep off the pressure should drop 0-20 PSI. That means that the pressure w/ the jeep off should be around 20-31 PSI. Well when I turn the jeep off, the pressure drops to zero. That is way below what it should be. What is wrong with the jeep. What should I replace. Please help as I need the jeep ready for it's first real offroad trip this weekend.
