Lets say you have a 89 Bronco (351W auto 4x4) and as your driving it all of a sudden dies.
You find that it has no spark. So you buy a coil and a module on the dizzy and still no go.
The dizzy rotor is turning, And fuel pump is working

Where would be some problem areas that you would suspect?
What sensors would stop the coil from working? Or is there a module stopping it?


anyone?

The fuseable link wires Ford used a lot of, and you apparently have a SHORT in one that feeds the Distributor.....
Or the Hall Effects type pickup inside the dizzy...

The injectors are not getting a pulse either.

Ignition switch?

Ive thought the same. A shop is going over it too.Ill keep ya's up to date.

No injector pulse? Sounds like the hall effect or fusible link to me, like FE said. Does it have a factory tach? The computer needs an RPM reading to pulse the injectors...not sure if EEC-IV uses the hall effect for both the coil and the injectors.
I would check the fusible links first (test light at the coil wires).
My guess is the hall effect in the dizzy is bad, though.

The vehicle was accel'ing and the throttle was backed off to coast down a bit due to a little to much speed. When the accell. peddle waspressed it had no more go.
It ran great prior to this too. Is there another sensor that would throw this all thru a loop? Idle, TPS?

I'd check your throttle position sensor then. It should be a module on the side of the throttle body. I had a '87 tempo freak out once because that sensor went bad.
