Question about 2000 Mercury Mystique

3 Answers

2000 Mercury Mystique while idling, started to idle ruff then died. and would not start. Mechanic said it is the fuel pump. $600 to install. I see that the Internet shows that the fuel pump is accessable from the back sit. Is this true, if so then the labor to change the fuel pump should not be so high?

I agree sounds like you have lost the fuel pump. I looked up the labor time and the part cost, the average shop charge for this repair is $538.00 Reference is webmd.com

    Yes, I would say that such a price is outrageous. I replaced the fuel pump myself and compared to lots of repairs, it is a piece of cake. The fact that to access the fuel tank, all you have to do is remove the backseat, is HUGE. I could understand that dropping the tank might justify alot more money, but you don't have to drop the tank. Personally, I slowly inched the metal lock ring out with screwdrivers, a hammer and some cursing. It is slow going, but you can do it.

    I was a little confused about how to hook up the new fuel pump, filters, etc. So, I called the support line listed on the company's web site - I called the one that was intended for auto mechanics. The guy I talked to said it was just fine to call the mechanic line. This guy said he had been on the company's assembly line for 25 years and he truly did know this pump frontwards and backwards. He said that the Mystique had a history of fuel pump problems for a couple of reasons.

    The plastic housing that the pump is fitted down inside of was an existing design that did not really fit the pump that was used. The little filter bags did not have enough room to stretch out and really wasn't as large as it should have been, so they tended to get clogged. I think he said that it also could have used more circulation area underneath it. At any rate, Mercury eventually designed a new housing and retrofit it at dealerships. This guy said that it would probably not be too hard to find one in the junkyard. There are other sites that talk about how to take out the old one and put in the redesigned housing. Apparently this involves removing the metal tabs that hold the old one in place on the floor of the fuel tank. Me, I just used the old housing and the old style filter and if it clogs up in the future, I guess I will do it again.


    I drove my car until there was very little gas in the tank and then just siphoned it out of the tank into a gas can.

Yes that sounds like a failing fuel pump or a defective MAF sensor, both of which will not set a fault code. Why didn't this so called mechanic check fuel pressure?

Starts but wont hold an idle . dies if your not on the gas pedel.runs good after you get it moving


The problem you describe could be result of a dirty of defective Idle Air Control (IAC) sensor/motor. This sensor is located on your vehicles, throttle body. The purpose of this sensor is to control the car's idle under various operating conditions including ambient temperature. In order for it to function correctly, the internal components must be clean (meaning, little or no carbon build up) and it must be undamaged. Sometimes the IAC can be cleaned; however, if this cleaning procedure is not properly done, the IAC can become damaged. This sensor is also sometimes called the "Cold Start" sensor and is located on your Throttle Body (easy to ckean and replace). A new IAC will cost $50-$100. My guess is your IAC needs to be cleaned or replaced. Good Luck!

I have a 2000 mystique with a v-6 . Replaced fuel pump and filter. Still have same problem idles but no off idle throttle. Scaned car has a code of low fuel pressure. Could this be a pressure regulator?


More than likely, yes. If the regulator is controlled by a vacuum feed, try removing the hose from it and run the engine. If you feel that it will run off-idle after you've done this, replace the regulator and be on your way.
