How are you testing for spark?

Spark plug wire connected to spark plug grounded to top of throttle body
Automotive Expert
OK. Good. Do me a quick test please. Turn the key to on and see if the check engine warning light comes on. Then try to start the engine and see if the check engine light goes out while the engine is cranking over.

Check engine light does turn on when turning key to on position then when turning key over to crank, check engine light goes out.
Automotive Expert
OK. That tells me the crank sensor is good and the PCM (Engine Computer) is getting and RPM signal. Check for 12 volts on the Red wire at the coil, and then try cranking the engine over and checking for pulsed power on the tan wire at the coil.

Red wire at coil has 12 volts with 12 volt test light and no power at negative unless I create a closed circuit. Example 12 volt test light touching tan wire which should be negative on coil and other end connected to positive on battery post but only if I turn distributor by hand a hair circuit light will turn on.
Automotive Expert
OK. Do me a favor and use insulated pliers and have a helper crank the engine while you pull the coil wire slightly away from the distributor and see if you are getting spark from the coil.

No spark from coil
Automotive Expert
OK. Have you replaced the Ignition module yet? It is mounted on the radiator support on the drivers side of the engine bay.

No, haven’t replaced it. I took it out cleaned it. Meaning air and wiped with damp cloth. Checked for any damage. Truck does have 500,000 miles on odometer not sure if it had ever been replaced.
Automotive Expert
Those are supposed to have insulation grease on the back side of them to help with heat dissipation. But they can fail quickly. Especially after 500,000 miles.

Definitely no grease light film of dirt and dirt clay. Any suggestions?
Automotive Expert
I would get one from your local auto parts store. And make sure it comes with the dielectric grease to coat the back side of it. Of course when they open tomorrow.

Okay. Would a oil pressure sensor coming from oil pan keep truck from getting spark if wire got spliced fully disconnected.
Automotive Expert
Not on your 1993 Ranger. It was somewhat basic for engine elctronics.

Okay. Thank you so much. I value your time and I had a good experience. Will definitely recommend to others.
Automotive Expert
Thank you. You are very welcome.
