The other day, I started the vehicle and attempted to drive out of a parking lot, the vehicle was running very rough and eventually died and since that day, I have not been able to start the vehicle.

I thought the fuel filter was clogged so I replaced it, however, when I blew through the filter, there was no apparent restriction.

In the engine cabin, there appears to be plenty of fuel in the fuel line. I sprayed the intake with ether, and the vehicle started and ran for a few seconds.

So there sits the van and I really need to get the beast back on the road.

. Test all under hood and under dash fuses with a test light or multimeter.

. Check for codes.

. Check for fuel. Can you hear the fuel pump run, when the ignition switch is turned to ON? If so, turn the ignition switch to ON, until the fuel pump stops running. Then, turn the ignition switch to OFF. Repeat this process two more times, to fully pressurize the fuel rail. Now, turn the ignition switch to START and see if the engine fires up.

. Replace the Iridium spark plugs (Motorcraft only), if they have not been changed in 50,000 miles. Don't skip the rear plugs.

. Replace the ignition coil and spark plug wires, if they have not been changed in 100,000 miles.

. Replace the Camshaft Position Sensor and the Crankshaft Position Sensor, in that order, if the problem persists. Try starting the engine, after each sensor is replaced.
