Having problems with your 1998 Ford Windstar ?

1998 ford windstar engine will start and run for a couple minutes then die, i have tried a new coil pack and new plugs still it starts and dies if i turn key on i can hear fuel pump run and it won't shut off if i wait a few minutes and turn key on again the pump will come on and turn off when it is primed and van will start then die after a few minutes soo i pulled plug wire and sarted van and when it died i tried to sart again and noticed there was no spark but if i let it sit it will have spar

You have a crank signal issue. The PCM opens the injectors, fires the spark, and runs the pump based on a signal from the crank shaft position sensor (CKP) and all of these problems will occur if the signal is intermittent from the CKP. The sensor is located by the crank shaft pulley, where you find your serpentine belt. It has two bolts and an electrical connector. Try the testing procedure below.

The CKP sensor, located on the engine front cover near the crankshaft \015\012pulley, is used to determine crankshaft position and crankshaft rpm. The\015\012 sensor is a magnetic reluctance type which senses the passing of teeth \015\012on a tone wheel because the teeth disrupt the magnetic field of the \015\012sensor. This disruption creates a voltage fluctuation, which is \015\012monitored by the PCM.

\015\012\015\012
    \015\012
  1. \015\012Measure the voltage between the sensor CKP sensor terminals by backprobing the sensor connector.\015\012
  2. \015\012
\015\012
\015\012\015\012If the connector cannot be backprobed, fabricate or purchase a test harness.\015\012
\015\012
    \015\012
  1. \015\012Sensor voltage should be more than 0.1 volt DC with the engine running and should vary with engine RPM.\015\012
  2. \015\012 \015\012
  3. \015\012If voltage is not within specification, the sensor may be faulty.\015\012
  4. \015\012
\015\012You'll also want to check the wires for breaks and tears. If the wires are soaked in oil this can break down the insulation and allow corrosion to get inside the wire and cause issues like this as well. You can also check while it is running by moving the wires around. Once the wires get warm they increase in resistance. If you are able, check the continuity resistance between the sensor and the module with an ohmmeter.
Hi and welcome to FixYa!

\015\012As a first course of action please open the hood and remove the positive battery connector and let it sit for atleast 5mins. to reset the system then reconnect it. Once the system is resetted we may get rid of the problem.
\015\012
\015\012If the problem still persists then we may have a possiblem PCM failure. Please swap the PCM and observe how it goes.
