No Spark in 2.9l

[NB4life]

I had new spark plugs and cap and rotor so i changed those and still nothing, the coil is fine so thats not it. seen some stuff about the TFI which i know nothing about and also checking the grounds which all seem fine. how do I find out what I need to fix?

Before it would crank and just not start and now it acts like the battery is dead. I turn it over and it just clunks but the battery have full charge and is connected. I dont know what to do and I need this fixed so i can get back to work since its my only rig.

How old is the battery? Is there corresion on the battery cables? Have you actually CHECKED the voltage the battery is holding? Should be about 12.6 volts being stored.

i just cleaned the terminals and checked it and its at 12 volts, still cranks but no spark. doing some research it looks like it could be the coil ground wire and mine goes to a connector that has a ground in it and it looks like it has some oil in it. could that be it?

oh ya and i got it cranking again by cleaning the terminals
