96 F 250 NO START NO SPARK
i have a 96 f 250 with the 5.8L that will not start its getting all the fuel it needs but will not get spark. ive replaced the cap, rotor, plugs, wires, coil, ignition control module, and even the computer and it still will not get any spark. so i moved to the wiring and tested every wire the way i need to and none of the wires are broken, smashed, or touching anything, ive tested everything on another truck and it fires right up. i dont know what to do with it now

Does the truck have a tachometer? If so, does it display anything while cranking the engine over? It should.....If not you can connect a test light to the coil, crank over the engine, it should blink.
Have you verified you have +12VDC at the coil with the key on? If you have 12VDC on the positive side of the coil do you also get the same on the negative side. Another quick test is to momentarily ground the negative side of the coil with the key on, you should get a spark.
If the tach reads nothing or the test light does not blink then you probably have a bad PIP (aka stator) in the distributor. This is assuming you have voltage at the coil. You have replaced darn near everything else, the PIP is the last thing left assuming the wiring is good. I realize you said you traced the wires, but without being there I have no idea what procedure you used.

Check to see if you have a ground at the distributor plug. The distributor is the source of the ground for the Ignition system.

its a brand new pip. there was no need to change the distributor. and yes i have my ground at the distributor

Below is the diagram for your ignition:

If you have verified the parts and all the wiring is intact then I suspect a bad PCM. I have also seen a few instances where the shield around the wires rubs through which shorts the signal(s) to ground. Usually there is a code associated with the problem.

Hey my 96 just got out of the shop with the no spark no start as well. The mechanic replaced the ignition control module as well as a fuse to the ecm. Runs fine now. I hated to pay a mechanic to change these things out because they are simple. I was having trouble pin pointing the problem

It is the wrong one. It will set an error code in Computer Memory.
So if you live in a state the checks codes you will not pass.
The Gray one is not made for the computer you have so the computer can not control it right.
It will not start as easy, have worse MPG, put out more pollution, and you will not have as much power.
Other than that it will run just fine.
