1990 Ford Taurus Car Not Starting

Start with the basics. Check for spark. For this, you can use an inline spark tester. Observe for spark during cranking. Also, check for fuel pressure. There is a test port on the fuel rail. You can attach a gauge there to check for fuel pressure.

You need THREE basic things for the engine to run:
1) Fuel and air mixture
2) Spark - at the correct time
3) compression

One of these 3 things is missing.
Let me know which one is missing, and I can give you some more help on diagnosis.

Hope I have been of some help.

Check injector pulse
check firing order
do a compression test
check for spark
check TPS volts
when key on do u have check engine light on (you should )if not check eec relay
