Fuel Pump Without Power

Postby mckaiser » Tue Sep 10, 2013 1:36 pm



Hey y'all
So I've been through the ringer with my 84' GL 1200. Long story short, I had to replace the solenoid, and in the process managed to fry some wires (clutch diode, neutral gear sensor wire). I replaced a few things, like the clutch diode, but I sent the neutral gear sensor wire to ground because putting in a new one was going to be quite the process.
So after I got the starter motor to sound, I now can't get the fuel pump to work. The pump itself is fine, but doesn't get power. The relay is giving out power, so I'm pretty sure that's good. I replaced the regulator/rectifier with one I had lying around. Still nothing...
I'll go through and start testing more wires, but I'm wondering if anyone has any thoughts on what else this might be? More specifically, could it be the engine kill switch wire has a short and isn't allowing current to the fuel pump? Any thoughts would be really appreciated! Thanks!

Put simply.
No spark no fuel volts.
The fuel relay supplies power to the pump IF it needs it and only if there is spark.
The volts on the pump only appear for just a moment.Just enough time to get it to pulse.It is not a continuous voltage.
