Hey guys.
73 1.7 D-Jet. 3 port Bosch fuel pump (now located under the fuel tank) runs constantly and is a bit loud. I read that it is supposed to run for 1-1.5 seconds and stop with key on engine off. Checked wiring and found it is wired directly to Fuse #8 on the fuse panel. Where should it be wired? Side note. Car sat for 5 years before i rescued it and the fuel pump had power but didn't run until i whacked it a few times. Thanks in advance, You guys are awesome and your expertise is much appreciated. |

There is a good reason why the fuel pump only runs on one of three times.
1- for 1.5 seconds when the key is turned to on to prime the fuel system, 2- when the key is turned to start, 3- when the engine is turning more than 100 RPM's. If you have a fire in the engine bay and the fuel pumps continues to run, the fuel feeds the fire, not a good thing! With key on and engine stopped, the pump should stop as it's really not needed to support running. These car are noted for having fires! It is in your best interest to get it fixed correctly. Tom |
