1989 F-150 5.0 No Spark

I have a F-150 4 x 4 5.0 L engine Automatic Trans. with no spark. I have replaced the coil and got a used computer for it. I checked all the grounds unless I missed some. At first I had spark and I used either then it would fire up for a couple seconds I replace the fuel pump and filter under the cab. Then after testing no spark from the coil. I have replaced all the sensors with used ones a few years back. Can anyone give me an idea what to check next. I have not taken it in for testing the computer and componants due to everyone wants an arm and a leg just to hook it up.
Thanks Rod

It's a good idea to replace the TFI (ICM) & the PIP (Stator) at the same time.Ford Fuel Injection Stator (RPM)
