No. Pin #7 at main relay does not have any voltage.
If I jumper wire #5 to #7 I can give #7 power that way. Otherwise #7 has 0 voltage.

I am going to do some more continuity checks between sensors and ECU pins. Also check ECU ground pins for continuity to ground. Maybe tomorrow if it does not pour rain. Going to babysit my grandson now.
Thanks for your help!

#7 goes straight to the fuse panel so I would say that is the issue. Check the wiring diagrams to confirm #7 on the PGMFI

Okay. I will do a continuity check. Do you know which fuse #7 connects to?

Actually, I think #7 connects directly to the fuel pump harness. I did a continuity check from the main relay harness pin #7 to the fuel pump harness and there was continuity there. (No breaks in the wire.)
