Seagull81,
Don't know why your starter won't cooperate. Is it heat? Clicking when hot instead of turning the engine over?
I can't recall how many cables, grounds, batteries, starters of different kinds, heat shields and baffles I tried. All those efforts lasted at most three to six months. Then, no start when warm...
Finally the light came on. It's described in this thread, last post:
First Coast Cobra Club • View topic - Zephyr update June 2011
There's a link in that last post that shows how to wire up the solution: two solenoids. Don't use the type of solenoid in their photo (see link below).
Ford has used two solenoids forever. If they could have saved a few pennies by eliminating one of them I'm dang sure they would have.
Interestingly, the Chevy guys often use this technique to solve the same problem - by adding a second solenoid.
Coincidentally, there are two kinds of solenoids available for Fords: side post and top post. The side post ones are very fragile and flaky (technical term: they sometimes don't work but not all the time.) Here's a message that shows the correct ones to use:
First Coast Cobra Club • View topic - Tom's starter CLICK of doom. Solved?
It includes photos and a description.
It's possible this may help your problem.
It only took me nine years to figure it out. Just one guy's Odyssey...
