    I got a P1133 message code when vip checked the check engine light on my sunfire

    they told me to take it to the local dealer

    what does that code mean - gas, fuel pump o2 censor ect

    It could be a defective 02 sensor, or the wiring/circuit to that sensor and worst possible case would be a defective PCM (brain) module.

    This can all be tested by a competent diagnostician---no guessing required.

    I have been hearing a lot lately about fuel system cleaners and injector flushes to clean out "deposits". I thought I understood all about this but I'm wondering now if I do.

    So take me to school. Where do these deposits come from, do any of the dealer offered or over the counter products work and what exactly are they supose to cure? :confuse:

    Is this the modern equivalent to "blowing the carbon out" by racing up and down the highway?

    Please help.
    I have a 1992 Cherokee Jeep and it died on the highway. There appears to be no power going to the fuel pump. Any ideas on finding out where the power has broken down?

    If nobody is able to answer your question that specifically knows about your year/make/model, then you can probably get a set of electrical schematics (and service manual) from for a cheap fee.

    I'd suspect either a fuse, or a relay.
  • I am wondering where the fuel filter is for the 2000 chrysler concorde lxi 3.2 L? Also we are gonna change the fuel pump and want to know if you have to drop the gas tank or if you can get to it threw the trunk?
  • A combination fuel filter and fuel pressure regulator is used on all gas powered engines. It is located on the top of the fuel pump module.

    The fuel pump module is an in-tank unit with an integral fuel level sensor and pressure regulator.

    Yes you have to remove the fuel tank.

    I filled my tank yesterday evening in my 153,000 mile 2002 Highlander Limited AWD V6. Then went through an automatic car wash before driving five miles home. When I got out of the Highlander I saw the gas cap was off and was off during the car wash!

    No issue with my five mile drive home.

    What would you do to make sure it keeps running right after this error?

    And now that I have reinstalled the gas cap properly, can I prevent the check engine light from coming on?

    (I live in a fairly cold climate near the Indiana/Michigan state line.)

    May pour a tank of STP gas cleaner into the tank. It's suppose to remove/isolate any water... though if more than a few ounces got in I doubt it would do any good. May have trouble with gas line freezing when it gets cold. Could siphon remaining gas out.
  • Depends how much water got in there. It has settled to the bottom of the tank. I'd say you might either never go below 1/4 full if you can, or you can 'test' things out by deliberately going to 1/8th full or so and if the car starts to sputter, you might have to drain the gas tank to get rid of that much water.

    If it's just a teeny bit of water, the engine will burn that up after gasping a few times.
  • My 93 Escort LX hit a deer a few weeks ago, and though I made it home I had to replace many parts of the body/radiator. Now, when I put the key in and turn until the fuel pump comes on, a flow of gas comes out the metal relief valve pipe which is connected to the top of the fuel filter mounted on the firewall. Any idea how to replace this valve without draining all the gas? :confuse:

    Remove the connector and stuff a sharpened pencil in the connection, if it will snuggly fit. I've used this many times to block fuel flow. Of course, do NOT do this inside any building or near ANY open flame source. Dealing with gasoline at any time could cause a massive fire.

    Put in 2 or 3 bottles of "Heet" or some other such water removal treatment. This is basically rubbing alcohol, which will combine with the water and then flow on thru fuel system and be burned, taking any water out of the tank.
  • Maybe tiny amounts of water.
  • I have an 01 sportage and am getting no juice to fuel pump. Replaced f.p. relay and main power relay as well as main power fuse, still no power. Are there more than one relay for f.p.?any ideas would be appreciated
  • Fuel Pump Operation

    1. Connect the data link connector terminals FUEL PUMP and B+ with a jumper wire.
    2. Remove the fuel filler cap.
    3. Turn the ignition switch ON .
    4. Determine if the fuel pump is running by listening for the sound of it at the fuel filler inlet.
    5. Install the fuel filler cap.
    6. If no sound was heard, measure the voltage between the fuel pump connector wire (G/Y) to chassis ground. Voltage: About 12 V
    7. If not correct voltage, check the fuel pump relay and related wiring harness.
    8. If you do not measure 12 V , check for continuity between fuel pump connector terminal wires (G/Y) and (B).
    9. If there is continuity, replace the fuel pump.

    10. If there is no continuity, repair the ground circuit.

    has your daily commute changed? have you kept up with maintenance? has the gas changed in your area, meaning has your gas stations switched to using E10 (10% ethanol)?
