I have no power to the fuel pump


Asked by Nov 05, 2015 at 07:13 AM about the 2003 Hyundai Sonata LX

Question type: Maintenance & Repair

I have no power to the fuel pump, I checked every wire on the plug and
there's no power getting to it, where does the power actually come from ?
is it from the fuel pump fuse under the hood or would it be coming from the
relay? the 1st issue is that I found the wire to the crankshaft position sensor
all burnt up and broken so of course it shorted out and blew the fuse, I
have this part on order coming in tomorrow but meanwhile I wanted to work
on why there's no power to the fuel pump,where is the relay for the fuel
pump located, I'm assuming the power starts out from the fuse under the
hood and then to the really and then to the fuel pump, is this correct?  I
also removed the fuel pump and have a new one to go in but didn't want to
put it in yet until i resolve the power issue this way it doesn't  blow the new
pump, if that's possible. this is a v-6 by the way

Check your relay for the fuel pump , I had the same problem my Opel corsa


Ok I had that problem with a similar car...did you changed the battery for a new one???? Try that because sometimes the Volt is not sufficient when the battery is broked....try a new battery and let me know. ;)
