2005 Volvo XC90 Q&A
2005 Volvo XC90 Question: What is a fuel Modulator and how does it relate to a Fuel Pump?
My check engine light came on and my car just died while I was driving it. I have a 2005 XC90 Volvo. I bought an extended warranty that covers replacing the fuel pump if needed, but I'm being told it's the Fuel Modulator or Fuel Module that is bad and they have to take out the interior of my car to replace it. So they are charging me for this at the tune of $800+. The dealer said when they are in there they can check the Fuel Pump and if it's bad replace it under the warrantly. What I want to know is where is this Fuel Modulator - is it part of the Fuel Pump? Or is it a "sensor" and if it goes bad does that mean the fuel pump is bad too? Can they just replace the pump and not replace the Fuel Module? I was told by the dealer "the fuel module is not sending us a signal so we know it's bad " (it's not covered under my warranty). Can you tell me what a Fuel Module is and how much does it cost and do they normally breakdown because the Fuel Pump breaks down first? Which goes first??? Thank you. - Presious
Unfortunately the Fuel Pump Drive Module is a common problem. Originally it's located under the right-rear wheel housing cover and it pretty much open to the environment. When it fails and replacement is necessary it needs to be relocated to under the rear seats, therefor a new - extended length- cable harness and connector required. On it's new location it will be protected from the external environments and should last a lot longer. I have no idea why Ford placed this unit for its original location, it wasn't a great engineering idea. If the extended warranty covers control modules, they should pay for it. It's a good idea to get the fuel pump checked also. If you post an e-mail I can send you the whole procedure that needs to be done for your better understanding. Zee - ZeeTech
