Please help me if you can.
I have a 1997 Explorer with SOHC V6.
It turns over but wont start. I have tested the fuel rail pressure test valve and fuel is there and shoots out a few feet.
I checked for spark on one of the wires with a spark tester. There is no spark when cranking. I then put the spark tester into the coil (to eliminate the spark plug wire) and I don't have a spark there either.
I checked for 12v battery power coming into the coil and it shows it has 12v. So I suspect the coil is faulty.
My other troubleshooting steps are:
My readings on the primary resistance between positive and the 3 negatives on the coil seem good at 0.7 ohms for each of the three.
The secondary resistance seems like it might be okay too.
Between 3-4 13230 ohms
Between 2-6 12920 ohms
Between 1-5 13290 ohms
----
I just got a new Motorcraft coil and it reads very similarly
Between 3-4 13170 ohms
Between 2-6 13120 ohms
Between 1-5 13060 ohms
and the primary resistance on the new coil is about the same at 0.5 - 0.6 ohms.
According to the troubleshooting, is my old coil probably okay? Is the resistance a proven test? Or can it still be a faulty coil even with my readings being similar to the new coil?
Could it be something else? Like Crankshaft Position Sensor? Is there a procedure to test the sensor? If it is bad will it still file the coil?
Thanks!
