No spark in the spark plugs

I have no spark coming from my spark plugs. Put a spark plug tester on an nothing. Checked my coil pack even switched it out with a different one and nothing.checked the distributor it's turning but no spark any where. Any ideas?

Did u check the ignition fuses under the hood. Allways follow power issues backwards you've checked most of it plugs. Dist. Coil. Now on to ignition. Fuses etc. There are a lot of good diagrams online.

how did you test the coil? did you test resistance, or check for spark on the coil wire? also check voltage on the + wire of the coil.

Not sure on 94 but most 5.0 had TFI module. They were normally the cause of no spark.

Battery is fully charged correct? Check cables?
You've checked for spark at the plugs, go backwards as suggested.
Check the cap & rotor.
Test the PIP
Test the TFI module
Test the coil


Not finding any problems in those areas may indicate an issue with the ECU.
