95 explorer 4.0 liter no spark

I ran before he changed the plugs and wires now it has no spark. there is power through the ign fuse and power to the coils so I changed the coils still no spark the next thing to change is the crank sensor. he has a parts car so so far it is free except for the Pepsi he also has a new brain box and a used ign module i have heard of the trick of putting a t pin in the top wire of the module and sparking it to ground to take the place of the crank sensor and to test the module with the key on it should spark, if it doesn't it is the module if it does it is the crank sensor . is there a cam sensor?

Yes, there is a cam sensor, but it is not your problem. The 1995 4.0 has no distributor; its spark comes from an EDIS ignition module that fires the coil pack using the crank sensor signal alone. The cam sensor sits where a distributor would have been and is used for injector timing, so it does not stop spark.

That also means the test-light trick you heard about is for engines with a distributor and a TFI module, not for this one. With power to the coil pack and no spark on any cylinder, the short list is:

1. The crank sensor, on the front of the engine by the crank pulley, and its connector. With the sensor unplugged, an ohmmeter across its two terminals should show a reading rather than open, and while cranking it should put out a small AC voltage.
2. The toothed trigger wheel behind the crank pulley. A bent or loose wheel gives the sensor nothing to read.
3. The EDIS module and its connectors. The spare module you have is the quickest test.

And because this started right after the plugs and wires, check that nothing got knocked loose: the coil pack connector and the crank sensor connector are both easy to bump.
