I HAVE RECENTLY REPLACED MY FUEL PUMP, CATALYC TWICE, SPARK PLUGS, WIRES AND DISTRIBUTAR CAP AND ROTOR. VAPOR SENSOR. THE VAN HAS BEEN RUNNING VERY SLUGGISH, LIKE VAPOR LOCKING DRIVING DOWN THE ROAD. AFTER REPLACEMENT OF ALL THE ABOVE, NOW IT HAS DIED WHILE DRIVING IT, AND WILL NOT RESTART.

If the engine's condition is in tip top shape-do below to determine if its fuel or spark problem that's if its cranking over and refuses to start

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
