2005 S type Fuel Pump System Failure
I just bought an 05 S type and was driving it home a few days ago when I noticed this "Fuel Pump System Failure" message. This happened right around 1/4 of a tank. Also once the message was displayed, the fuel tank gauge went all they way down to below E as if the computer just stopped reading the fuel quantity.
I pulled up the back seat and I see what looks like two fuel pumps? I opened up the passenger side by removing the plastic ring and plugs and what appears to be a fuel line off the top cap, and pulled up the fuel pump assembly. It all looked OK I suppose, was hoping to find a fuel hose lose.
So I'm thinking my next step is checking that both pumps work? Can I just send 12 volts down via the connector on both sides and listen for humming? Should I pull up the drivers side pump and also inspect hoses?
Just trying to brainstorm what is going on here. I filled up the tank to 3/4 yesterday and the message has went away thus far. I'm guessing it will come back at around 1/4 a tank.

Welcome to the forum John,
Don't forget to post an intro in the new members section.
Probably worth mentioning the 2005 fuel tank recall, does your vehicle fall into the range? Hopefully not.

Its just an S type. I thought it had two? OK well time to open the drivers side up and see what it looks like in there. If the pump seized would the car still run fine after I filled it up since it only has one? I was thinking it had two, a transfer pump as well, and thought that was on the passengers side. I wish I had some good manuals. I'm just going by a document I found online.

Ok, I'll take a look at the left side (drivers side) next. Guess i'll know by unplugging the sending unit wires, getting an ohm meter on it, and move the float to the extremes? guessing it needs to be linear as well?
#7
I searched the VIN from the link above, and it came back 0 recalls, so I suppose that is a good sign.

My plan is this weekend, remove both fuel pump assemblies for inspection and cleanup and hope I find what the problem is

Well I went out and pulled up the Drivers side fuel assembly, and yes your right, no electric pump on that side. Just what I would call a "motive flow" style jet pump that uses the right sides electrical pump flow to draw fuel out of the left side and pump it to the right. It looked fine, I was hoping to find a hose off or an obvious clog. Guessing sender unit has to be causing this now. I didn't have my ohm meter handy.

Well finally got to the bottom of this. The sensor checked out OK on the Drivers side fuel pump unit, but as you can see from the pictures, the motive flow (jet pump) was clogged up. After cleaning it out the message is gone! There is a plastic rectangular cap on the bottom of the pump that is glued on. You have to very carefully pry it away and hopefully the glue seals are break first. Than to remove the blue piece I pushed it out from the other side through one of the fuel line connectors using a small but long screwdriver. Beware when you do this you will destroy a small filter that is inside the line. I see no other way to get the blue part out without doing this and will just live without that particular filter for now.

How to remove the retainer metal clamp ring for the fuel pump
Hi Guys
I was out of the country for over a year and did not get to start the car, was fine when I left, but now it wont start, it cranks, new battery, added 10 gallons of new fuel, checked all fuses, reset the fuel pump shut down switch, i don't hear the fuel pump come on. I want to remove the fuel pump to check and see if its stuck, but there is a metal clamp, do i need to remove it first?
I had the dealer replace the fuel tank and both fuel pumps 2 years ago, under the recall
need your help and advise
