Hi folks,
My son's F250 started intermittently failing with Battery Issues.
He changed both batteries and replaced the Alternator as it seemed to stop charging properly.
The other Symptom that he saw was Relay 3 was buzzing intermittently.
This is the top Right Relay in the Fuse box. We looked in the Ford Service Manual but it did not seem to be involved with the charging system in any way.
Now the truck will not start at all, the Engine will turn over, the Engine Start light doesn't come on at all.
I gave him an ODB II analyser to plug in, but it states " Failing to connect to PCM "
What would our next logical step be ?
