Sounds like No spark

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it

Ok I know there is power going to the ignition coil and the distributor, those have been tested with a test lamp. Where are these other sensors located that you are refering to?

Disregard the sensors-test the distributor pick-up coil and the ignition control module.

Does the test lamp flash on the out put of the coil when you crank it over? Look at the distributor and see if there is a module mounted on it. That is the TFI module. It has the plug and 2 bolts(tiny) and after you undue them it pulls down. You can take that to an Auto store and they can test it but I have had a similiar problem and that was the problem. It should run you about $ 30 for the part.

I have removed the TFI module and taken it to a parts store and it did test bad. I just want to thank you for your help. Now as soon as I can come up with the 37 bucks to purchase a new one I will have it back on the road. I have also discovered while searching other parts of the world wide web that there is also a law suit on Ford about the location of this particular TFI module and on many, many other models. Any ideas on how to relocate the TFI module?
