Try using a squirt bottle of gas to squirt into the throttlebody mouth ( you'll need to disconnect the breather hose from it) while starting. Don't use starting fluid! It has a tendency to catch fire!
If it starts for a little bit, then dies, you'll know the problem is in the fuel supply system. There are a number of fail-safes in the system. ( pressure switch, rotation sensor, G-switch...)

Without testing we'd only be guessing ! Do you want to replace a bunch of parts till the problem is fixed ? Hooking up a scanner an looking at engine management system sensor's (data ) inputs to the engine computer would be the first place to start. If you don't have the ability to do this , suggest you take it to a qualified repair shop . Or learn automotive Engine system diagnostic's . A lot of thing's could cause the problem your having . Do you know how to test automotive electrical an electronic system's ?

1998 Ford Windstar Minivan: 1. I sometimes get an extended crank when trying to start engine after I've made a short trip. 2. My interior lights won't go out after I turn the engine off, so I...


YOU MAY HAVE A BAD DOOR AJAR SWITCH. HOWEVER, YO HAVE A TIMER THAT SHUTS OFF THE INTERIOR LIGHTS AFTER 300 MINUTES. IT'S CALLED A BATTERY SAVER FEATURE. TEST IT OUT.

THE EXTENDED CRANK MAY BE A CHECK VALVE IN THE FUEL PUMP IN THE TANK, ALLOWING PRESSURE TO DROP WHEN YOU TURN THE ENGINE OFF.
OR A BAD FUEL PRESSURE REGULATOR ON THE ENGIEN FUEL RAIL.

TRY THIS TEST, TURN KEY TO "ON" POSITION, WAIT 5 SECONDS, SHUT OFF KEY FOR 30 SECONDS. TURN KEY ON, WAIT 5 SECONDS, THEN START ENGINE. IF IT STARTS RIGHT UP, YOU ARE LOSING FUEL PRESSURE WITH ENGINE OFF.

THIS BUILDS UP PRESSURE IF IT DROPPED DURING SHUT DOWN.
REPORT TEST RESULTS.

PLEAE RATE, THANKS
