Trying to diagnose a no start on my 2.9. Been sitting awhile.
Following procedure and have everything good up until tests wiring going into the TFI module. Getting 12 volts on wire #4 w/ ignition on. Forgot the color. But wire #6 (solid black wire on the end of the plug going into tfi) should be ground. When probing with multi meter. Positive end to positive terminal ground end to back wire on tfi harness im not getting anything. It should be reading 12 volts if the ground is good.
Am I doing this right? Solid black wire is the ground right?
If im right then obviously that ground is shorted. Anyone know where to follow it to? Just sorta goes into a bundle. Thinking of cutting it and running a wire to a known ground. But I want to be sure that the solid black wire going to the Tfi is indeed a ground and should indeed measure voltage when testing in the manner I described.
