Thanks for the input. Not sure how a short would lead to 6.8V. Seems to me a short is zero.
The wiring is exactly as it is in the diagram above. Green/Yellow to the inertia switch and pink/black out of the switch to the pump.
The part you can't see in that diagram is the red (hot) wire into the relay and that the green/yellow come out of the relay to the inertia switch.
With key on I put a probe on the red wire coming out of the bottom of the relay (which is really power into the relay) and it reads the full 12V. On the two green/yellow wires coming out of the bottom of the relay socket, it reads 6.8V. It reads 6.8V into and out of the inertia switch, 6.8V into the pump and 6.8 into the pump with a jumper calbe providing ground straight to the battery's ground.
I actually removed that little black box that holds the relays (fuel pump/AC etc.) from the fiberglass cross member and pulled the plastic bottom off of it and put a probe on the spade connectors that the relay plugs in to. That is where the red wire shows 12.8V and the green/yellow show 6.8V.
What I'm telling you is that 12V goes into the relay and 6.8V comes out. The relay has a relay diagram on the side. It is not crystal clear what is what but I swear there is a resistance diagram on that picture.
If anyone out there has the time and drive, please do what I did. The relay box snaps right out and the bottom snaps right off of the box. You can put a multimeter on the bottom of the spade connectors and the ground of the multimeter to the battery with key on. Tell me what you get.
Ok, were getting somewhere. What you have is a high resistance contact,
NOT a short. If your getting 6.8V out at the relay, theres you answer, almost.
Now what is it? two possibilities. One is the relay itself has bad contacts
internally, A new or swapped relay will tell you if thats it. The other is
bad contacts on the Socket going to the relay. Look down into the
socket where the relay plugs in. Does it look burnt or discolored?
if so, you found your answer.
If its a 98 or newer, you have separate relays, 97 or older, CCRM
