1993 Ford Taurus

A bit of diagnosis is in order - unless you just want to throw parts at it until it is fixed.

Is it hard to start because it turns over slowly? That might indicate a problem with the starter, battery, or starting circuit. Low voltage when cranking can also cause a loss of spark or fuel pressure. The electronics need a minimum voltage to function correctly.

Once you have verified that it is cranking at the proper speed and voltage (minimum 10 volts at cranking), you may proceed to checking fuel and spark. Check for spark using an inline spark tester. If spark is present, check for the presence of moisture under the distributor cap. Also check fuel pressure.

If spark is not present, check resistance of coil primary winding (at the terminals for the 2-wire connector on the low voltage side). Resistance should be around 5 to 10 ohms (I'm not sure, I have to look this one up).

If the problem has still not been found, I recommend that you replace the ignition module and PIP sensor (also called a pickup coil) inside the distributor.
