With intermittent issues, you have to test when the problem is on going. To say somebody tested it in the past, doesn't mean anything. Even if you can hear the fuel pump, doesn't mean the pressure is good. Use a fuel pressure gage.
When the problem is ongoing, use a noid lite, check for injector pulse. When the problem is ongoing, use some starter fluid in the intake, see if the engine will try to start. I take the air-duct loose from throttle-body, open throttle valve, spray a little in, stand back from vehicle, have helper crank it. When using any flamable spray, there is a safety issue. Safety is your responsibility. Unless your willing and able to do a little testing, WHEN THE PROBLEM IS ONGOING, I'm not sure how to help?
