95 F150 Can't pull codes (EECIV)

I have a 95 F150 4.9, 5spd, 160k miles. CEL came on this past weekend so I went to pull the codes (OBDI/EECIV). I hooked the reader up to the port and I get nothing. It doesn't cycle the system, it just sits there and returns nothing. Same result with KOEO and KOER. I know the reader is good since I also have a 95 Explorer and it works fine on that. I'm assuming that I'm not getting the correct signal(s) to the OBD port. How can I further diagnose this? thanks

Hold the clutch to the floor while performing the tests and see if that makes a difference.

Holding the clutch down didn't make any difference. Does anyone have a procedure for testing the connections at the OBD I plug(s)?

Does the fuel pumps run all the time the key is on with the engine NOT running?

No, fuel pumps are working properly in that it primes for a second or 2 when you turn the key on.
