Hi There -
Per the chart below, is pin #13 on the engine comaprtment 14 pin plug a true keyed power source? Being that the chart does not list the fuse it goes to (like it does on pin #8) I am a bit confused. I need to create a harness for my fuel pump and need a keyed power source for the relay. The PO of my car installed a faucet pump and ran it off of the positive side of the coil. I need to check again, but I am pretty confident that the original wires were removed, and for now, I want the new pump (carter 4070) to reside in the stock (rear) location. Thanks Very Much - (IMG:style_emoticons/default/beerchug.gif) Scott S Attached image(s) |

You are dealing with carbs right Scott? If so the fuel pump relay won't work as is. It requires the FI-ECU to do the logic that Valy posted.
I'm thinking though that it might be possible to rewire the relay board to use Valy's cct. Valy does the oil pressure sensor present a ground when pressure is there and high resistance without? That's how the solinoid activates? The normally off position powers the pump from the starter (starting but no oil pressure yet) then when the pressure gets up the relay makes and the power comes from switched power? |
