2000 Dodge Durango Moreno Valley

This is typical of fuel pressure bleeding down overtime. The fuel pump will run for one second each time you turn on the ignition switch, then it won't run again until you crank the engine. That one second is enough to get the fuel pressure up if it bled down a little overnight, but if it bled down to 0 psi, one second isn't long enough to raise the pressure to where the engine will start. Most commonly this is caused by a leaking injector and is more of a nuisance than anything. To verify this is the cause of the problem, turn the ignition switch to "run" without cranking the engine, turn it back off, wait for a couple of seconds, then turn it on again, wait a couple of seconds, then crank the engine. If that works consistently, you can try just turning the ignition switch on, then waiting a couple of seconds before you crank the engine. When you spin the switch quickly from "off" to "crank", that doesn't give the fuel pump time for its one-second burst to get the pressure up. By cranking the engine right away it bleeds the fuel pressure off as fast as it is trying to build up. The engine can't run if the fuel pressure is too low.
