I did it MY WAY ![]() ![]() ![]() Group: Members Posts: 1,337 Joined: 14-September 04 From: Simi Valley, CA Member No.: 2,757 Region Association: Southern California ![]() |
For some unknown reason, the PO had run the fuel pump off the Tail Light circuit, so I need to correct this. I tried other fuses in the fuse box, but they all seem to be either on all the time, or only on when specific things are turned on. So I decided to do things "better."
I would like to run a "switched" circuit to my fuse box, so I can have the fuel pump active only when the engine is running (ignition in the ON position?). I have upgraded to the 15 fuse box and would like to create two new switched fuse circuits for my fuel pump and my stereo (one each), that way I can get ahead of the game, and know exactly where everything is, rather than splicing more stuff and screwing around with the electrical system. Can you help/offer any suggestions? |

QUOTE(vsg914 @ Nov 26 2004, 04:15 PM) Hmm, I can pull the second or third and the pump still won't run. 75 model. Correct. There are 4 relay positions. The first one (starting from the front) is usually empty. That's the rear window defroster option. The second from the front is the "power supply" relay. It gives power to the fuel pump relay (not the fuel pump) and I think the FI too. The third relay from the front is the pump relay. This relay gets switched on from the second relay. This relay actually gives the fuel pump its power and also powers more FI stuff. The last relay is the heater blower relay. Relay 3 is required for the fuel pump to run. Relay 2 is required for relay 3 to run. So actually relay 2 is the fuel pump relay's relay (IMG:style_emoticons/default/biggrin.gif). Both 2 and 3 are needed to run the fuel pump. I guess they did this so the pump wouldn't run if the other circuit failed to power up the FI properly. BTW-relay 3 (from the front) is the second from the back. I went from the back so he wouldn't count the empty socket on position 1 (rear window defrost). |
