could really use some advice

hey guys im new here ive got a 94 ford ranger 2.3 with dual coil i know a little about these trucks but it was idleing the other day and just died since then ive replaced the fuel pump and filter along with the fuel pressure regulator now ive replaced the crank shaft position sensor and still have no spark im annoyed but it was a good running truck before this any help is appreciated

There is more than the crankshaft sensor involved with your ignition system. Here is a description.


The distributorless ignition system used by 1991-94 2.3L and 4.0L, and all 1995-99 engines is referred to as the Electronic Ignition (EI) system. It eliminates the conventional distributor by utilizing multiple ignition coils instead. The EI system consists of the following components:

1. Crankshaft Position (CKP) sensor
2. Ignition Control Module (ICM) (EEC-IV systems only)
3. Ignition coil(s)
4. The spark angle portion of the Powertrain Control Module (PCM)
5. Related wiring

The function of the ICM was incorporated into the PCM beginning with the EEC-V system; otherwise the newer system operates in the same manner.

Also when you were checking spark, were you checking on a drivers side or passenger side plug? On crank you'll only have spark on the passenger side...

And welcome to the show!

Only reliable way to test a gasoline engine that cranks but doesn't start is the 50/50 test

Spray fuel into the engine manually
Try to start
If it starts runs and dies, spark (and timing) is OK, fuel delivery is the issue
If it doesn't start then spark is the issue, or compression in the case of the 2.3l with timing belt
50/50 instant results on where to go next

yeah i checked the passenger side plugs i just replaced both coils and still no spark also i tried spraying fuel into the intake didnt hit a lick looks like all i have left that it could be is ignition control module wiring and the pcm is there any way i can test those individual items all i have is a test light. with the key on i have power to all 3 wires on both plugs for the coils which i thought was kinda odd

Not the PCM, it doesn't control spark for start up

Google: 1994 Ranger 2.3l test ICM

You will have power on all the terminals of the coils, that is normal. The control module grounds one of the terminals to charge the coil up, and then when it releases the ground that is when you get spark. If you pick the correct wire on the coil, when you crank the engine you should see the light on your testlight blink. That would be the ignition control module grounding and ungrounding the coil to make spark. So one side of the coil will stay lit solid all the time, the other side will blink when cranking. Just sitting there not cranking, they will all be lit solid with the testlight.
