I have a 1994 F150 5.0. I can't get any spark out of the coil I tried a new coil and I also put new plugs, wire, cap, rotor, new remote EIC that connects to the disributor. I am also not hearing the fuel pump run for 2 second when I turn the key on to try to start it. About a month ago I would turn the key on and off till i heard the fuel pump prime then it would start and would run for a few sec then it would shut off. I read in my repair manual to check the voltages on the eec (My ignition is eec-iv i think that is what it is called I don't have manual around) I tried checking it but im not sure if i an doing it right and im not sure if that is the problem. I there a simple solution that i am overlooking or is there a way to by-pass it so you can get spark and have the fuel pump prime. I also tried the relays under the hood. All advice welcome I am stumped on what the problem might be.

 

If the fuel pumps are not coming on why are you replacing the Ignition parts.

The PCM Power relay should click once when you turn on the key and again when you turn off the key.
The Fuel pump relay should click when the key is turned on and then fall out with another click in one second time out. This time out is controlled by the computer.
Let me know what you find at this point.

I am not getting spark and when i hear the fuel pump prime then i used to get spark and it would start . I tried moving the the relays around to see it i had a bad relay or are the different even though they can be switched

 

That means you are not getting power from your PCM Power relay on the red wire then.
Make sure the PCM power relay clicks when you turn on the key.
If it does not then you may have a problem with your Ignition switch that is located on top of the column down near the floor board. Also check the Ignition Switch plug to see if it is OK.

 

Would the pcm relay not getting power cause the fuel pump not to prime which in turn would not cause it to tell the coil not to spark also. When i turn the key I hear a click somewhere but then the fuel pump should prime and it is not doing it

 

You would still get spark but the Fuel pump relay would not do anything if the PCM Power relay was bad.
If no spark either then I would look at the Ignition Switch.

 

If your pcm does not have power, you will not have a spark. The pcm connection through the spout will load the TFI module.

To verify this, disconnect the spout connector. You should then have spark. Of course, the truck won't start because it won't have any gas.

There's a reason that I know this

 

Where is the spout connector at and what does it look like?

Sorry i think it is because i am work and the security will not let it open it

I am have the same issue that you describe. How/What did you do to rectify the problem?
Thanks

 

I am having the exact same problem...I have a 94 f150 I bought it not running an figured it was something simple. The person before me just finished replacing the neutral safety switch on it. Now I can seem to get it to spark I have replaced the distributor, tfi module, coil and have now tried a different pcm still no spark. So my question really is would or could this have something to do with the neutral safety switch. Could it possibly send a signal to have no spark...Any help would be great

 

No the neutral safety switch has nothing to do with spark, only cranking.
Does it have spark with the SPOUT removed?
