intermittent spark

[rudster]

89 ford festiva efi has intermittent spark, will run some times then not. until this happened ran great. have replaced plugs, cap, rotor, ignition module, pick up coil, and spark coil, computer. am out of stuff to replace. have checked all wiring, grounds etc. no one can figure it out. has anyone else run into this?

Possible poor contact in the fusable links? Pull them and check them for corrosion.

Are you sure you are losing spark and not losing fuel? If your positive its spark that your losing I would suggest that you check all the fusable links and the wiring to the box there mounted in. There is also a ground for the ignition system near the water neck on the front of the engine
