may not matter TOO much in this case but it's customary to list Make
Model year, eng etc.
What youre saying is that all ign-key-on indicators work other than Pump
cycle and Check lite.

jump it from where and where on the ccm? If you're talking about the FP
conn on EEC test connector, that means your fuel pump relay works...
means nothing else, did you find ign sw power on the ccm?

Then you need to locate the PCM relay on the CCM, right?.

You need at least a test lite and would be good to have a helper. And if
you find the problem is on the ccm?


If yours is a one of 150,000 like -say- the 93 tbird 3.8... just get the
part number off the ccm and call around the scrapyards.

You did press the fuel pump reset button - correct?

Check your grounds,
check the tilt switch in the trunk,
check the power relay tucked in next to the computer.

Not knowing year / model .. this info is for an 85 ford with EEC-IV
