    I have suddenly lost power to my turn signals, heat/AC blower control, radio.
    I recently had the fuel pump and related wiring replaced. Everything was working fine until yesterday. No radio, no fan, no turn signals. I haven't noticed anything else electrical not working. If they were all fed by the same fuse box, I would think that is where ...

      Maintenance will be expensive *when something goes wrong*. Its not the cost of a tune-up that there is concern about. Its the fact that its a Jag and diagnostics on Jags often requires the dealer and the dealer will generally have *no mercy* for your wallet, just as if it were a Mercedes Benz. Most local mechanics can do straight-forward jobs like brakes etc, but when something goes wrong with the heater controls or the chassis electronics you will spend thousands at the jaguar dealer. Aside from that, I like the car. The price sounds fair. I think you could flip it in a year for the same price if you wanted to. I bought a brand new Sovereign out of the showroom in '91, but it had the 6 cyl engine. The 12 cyl sounds nice but more noted for bragging rights rather than power.

      OK, Thank you Moving on, I also own a pristine 951 turbo 1986 Porsche with 30k miles. Im told I will need a new clutch at some point which the quote was around 2k w/labor. I only drive this vehicle in the summer avg. about 2k miles yrly. at most. Should I just maintain the If it isnt broke dont fix it mentality or be pro active? No slippage in the clutch is present.

      If it feels good leave it alone. Always remember that it was a "for profit enterprise" that told you that you will need a clutch...It will slip and you will get warning so no need to be proactive. Its not like it is your only vehicle and you would have a hardship if the clutch went quickly.

    Need instructions to replace a fuel pump on 1994 Honda del sol
    The car is not running at this point but if sprayed with starter fluid it will until the spray is consumed .

      First question - has the fuel system pressure been tested at the engine, and at the fuel pump outlet side? How have you determined the fuel pump is indeed faulty?

      Here are the fuel pump replacement steps;
      Remove seat.
      Unplug and remove fuel pump cover.
      Pull out fuel pump and sending unit assembly.
      Remove fuel pump.
      Remove sock if your pump didn't come with one.
      Replace fuel pump.
      Replace cover
      Plug back in
      Replace seats.
      Start engine and look for any leaks.

      Check the many on-line auto parts sources, such as;,, and - to list only a few sources. For example, they (Rock Auto) list the fuel pump (with strainer / sock) from around $25.00 for your vehicle

    How to check trams fluid on a 1998 XJR
    Mercedes Benz transmission
    • Jimm
      11/30/2012 Jimm
      There is no dipstick on your transmission. There is a fill plug that needs to be removed to check the level once the trans fluid temp reaches 30-40 degrees C. When the fluid is full it will drip out of that fill plug. The fill plug is the 8mm hex on the passenger rear of the transmission case.
      You should NOT use dexron III. The fluid that should be used is the Jag fluid which is Esso ATF LT 71141.

    Is there any reason that I should have the dealership change the oil as opposed to doing it myself?
    • Jimm
      11/17/2012 Jimm
      Unless you can spare the cost; comparing the typical dealership services cost to do-it-yourself - there is no question which is less expensive. You can usually change the engine oil and filter for a fraction - say around $15.00 to $30.00 with your own labor - as compared with the dealership.

      You might want to take a look at this technical bullitin. My car does the exact same thing. If you just start it up, give it 15 seconds to circulate the oil, and then flat-foot it, it'll prevent it from damaging itself until you get the service bullitin taken care of.

      Service Bullitin Number:30305 Date of Bulitin: Sept 01, 2002
      NHTSA Item Number:10012410

      Description: Misfire or hesitation when cold, along with possible illumination of malfunction indicator. DTCs P0300-P0306 may be present.

    Wiper trouble. Why doesn't my windshield wiper cut off in its start position?
    My wiper will not return to its off position. It stops where it wants to on the windshield when finished. Other than that it works fine. What is my problem?

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this).
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Faulty / clogged fuel filter
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires
