All: The intermittent fuel pump issue still lingers on our BB. Can anyone tell me where the wire (or wires) that feed pins 12 and 14 on the 14 pin connector are routed from the battery? It's obvious that it goes into, and returns from the hole in the firewall. But does it go all the way to the dash, or just under the passenger seat?

And the color, is it red/white or red/yellow?

This seems to be the cause of the problem. And check out my OBD 914 version below. Only way I could figure how to determine what was failing. Attached Image

It’s been at least 4 years since I’ve messed with my harness but my recollection is the red battery feeds from the battery to the relay board never leave the engine compartment.

I believe they go down toward and into the firewall boot but then go up to the relay board on the other side of the engine bay to the relay board under the shelf.

DMM is your friend.

Thought you had this solved by spreading the fuel pump relay (J17 on schematic) pins and tightening the relay board sockets - am I mistaken?
