  • Can anybody point me in the right direction? 2001 L300 3.0L V6

    Current Stats:

    Fuel Pressure: 40 (cranked) / 19 (key-over)
    Fuel: 1/2 Tank
    Battery: Working
    Current Codes: None w/ Previous Codes (Voltage / Transmission [which has been on-going; causing intermittent shifting issues until code resets])
    Current Condition: Vehicle Sitting after a Tow
    Engine: 3.0L V6
    Engine Mileage: 144K

    What I have done since it's been towed:

    A) Replaced all fuses with new ones
    B) Checked the fuel pressure (40 cranked) / 19 with key over
    C) Oil change
    D) Oil Filter change
    E) Fuel Filter Change
    F) PowerTrain Control Module (PCM) changed from stock "version II" to a Pick-N-Pull 03 LW300 "version III" which has been properly VIN Programmed via youtube.com/watch?v=8cqqVu8bHOM which worked perfectly as the expert explained.
    G) Used an Oreilly's OBDII reader and cleared codes with a jumpstart from my kind neighbor Nichole.

    It starts and looks as if it's going to idle; the service engine light remains on during this step; then it gets to 3000 RPM's when I am pushing the gas peddle a bunch before seizing. Can't seem to get past this part.

    I checked again for the fuel pressure and created this video as to what's happening at this time frame of this repair.

    Without knowing for certain; a couple things are popping in my head.

    1) Could it be the alternator? Hence; the not being able to keep alive. (However; given the weak RPM/idle -- it seems as if it has something to do with something else.)
    2) Could it be a sensor that isn't throwing a DTC code?

    * Updated @ 19:41 - Also to note: The shrader valve puked a bunch of fuel upon removal as opposed to exiting the outpour tubing - Seemed like it defeated the purpose and I used a brand new fuel pressure kit from amazon. It wasn't necessarily cheap either. I was wondering why it would do that... regardless of the pressure readings.

    Thank you!

    I did answer your other post yesterday. Here was my input....


    Your fuel pressure seems low. I found this ....

    Alldata says 39- 49 psi regulated and 65 psi unregulated at 12V

      What is the normal fuel pressure that I should be looking for? What possible scenarios would result in such things?

        My point was that you are approaching the minimum threshold of the specifications at 40 psi. The specs are 39-49 which were included within the quoted text I provided. Hypothetically you should be okay but how confident are you in the reading you are getting from your fuel pressure tester. Perhaps your fuel pump is on its way out or the pressure regulator is too restrictive. I'm not familiar with the L Series - is the pressure regulator part of the fuel filter? What brand of fuel filter did you use? Some are better than others.

          trottida,

          Thank you very much! I purchased the following tools for the fuel filter change + oil filter change + fuel pressure checker :

          My neighboor helped me jump my car today and I held the gas pedal down on the floor and rev'ed the engine to try and keep the engine running. This resulted in 3 things.

          1) The engine ran longer than before

          2) The engine started smoking

          3) The engine block seems to have tons of oil that must have spewed out when I over-filled after it originally broke down before the tow truck brought me back home.

          I am uploading YouTube videos and pictures now.

          Thank you all very much!

              Like I said, I'm not familiar with the L Series. I leased an LW200 MT for 4 years (01-05) but at that time I didn't do my own automotive maintenance. Is the Exogard fuel filter a recommended brand for replacement? I know with the S Series the Wix is recommended and others are questionable as far as quality. By questionable the fuel pressure was all over the map.

                Here are the picture attachments of the visible oil that seems to be leaked all over the engine.

                However the smoke was coming up from one of the oxygen sensors (or under) ; I am not certain which at this time. I was in the drivers seat. [See Video 1 & 2]

                  Series 1/9:

                  This seems to be the culprit - Drenched alternator & other parts of the engine.
