Van has been running with no symptoms. Wife backed it out of the garage about 30 feet and it died. I took the air tube off and squirted gas in the throttle body and it fired up.The fuel pump comes on when the key is turned on for the required few seconds.There is a line by the M Cyl. with a schrader valve in it that shows nothing when the valve is depressed. I even added gas to the tank to be sure. There are no codes. It is a 06 3.5 with 100K Kinda stumped?????
