Question about 2003 Infiniti FX35

2 Answers

Yesterday I tried to start my FX35 and it would not start initially. After 3 or 4 tries it started, but I had to accelerate the gas pedal for it to stay on (for the first minute)...Once on, it was ok, but I noticed lots of smoke coming out of the muffler. I have 220K miles on it (LOTS) and it has really never given me any problems. I did notice a few times before that it took me couple of tries to get it started, but never like this.

    Thanks. I took it into my local mechanic and he said he's going to run diagnosis on it...Hopefully he'll see the fault codes.

I suggest check for someone fault code there; sound like problem with the EGR or MAP/MAF sensors.

With this number code, we can send you other details.

    Keep early this information about How to Check Check Engine/Service Engine Soon Light Codes...

    Without OBD II

    On G20 models,
    the ECU is located behind the center console. On J30, M30 and Q45
    models, the ECU is located behind the RH kick panel.

    If a
    malfunction occurs within the ECU/fuel injection system, a diagnostic
    trouble code may be stored in the ECU and the ‘‘Check Engine’’ lamp will
    blink. There is also a lamp built into the ECU which will concurrently

    To read Code output, proceed as follows:

    Turn ignition On, but do not start engine.

    2. Using a small
    screwdriver, turn diagnostic mode selector switch, located on side of
    ECU, fully clockwise.

    3. Wait two seconds, then rotate switch to
    full counterclockwise position.

    4. A malfunction code can be
    read as the long (0.6 second) blink, indicating the first digit of a two
    digit number and the short (0.3 second) blink, indicating the second

    Note: Ensure that the diagnostic switch is to the
    full counterclockwise position whenever the vehicle is in use.


    On Infiniti's built after 96, connect a suitable Scan
    Tool to the DLC, located under the instrument panel fuse box cover
    (driver's left knee).

    Clearing Codes

    using a scan tool, follow tool manufacturer’s instructions to clear

    A second, though more time consuming method of clearing
    codes involves using a small screwdriver to turn the diagnostic mode
    selector switch, located on the side of the ECM/ECU, fully clockwise.
    After waiting two seconds, rotate the switch to the full
    counterclockwise position. The diagnosis will end and memory will then
    be cleared.

Sounds like you might have some problems with the ignition, i.e. a weak coil, high resistance in the spark plug wires, or worn plugs. Causing a weak spark at the plugs. On the computer side, coolant temperture sensor and/or O2 sensor, causing a rich condition when starting.

Will not start, flooded

Press the accelerator pedal to the floor and keep it there! Now turn over the vehicle, it will try to start and eventually will fire up, when that happens release the accelerator pedal and it should be all good!

I have infiniti fx35 2009. i can continuously hear some sound when i turn on a/c. but goes off when i accelerate. (If bearing - can it be replaced?)

I recommend that you replace it as soon as possible; My dad had a similar problem that you had then when he turn it on it made a noise at first and he left it for at least a couple weeks or so and 1 day his car started to loose power and he was doing 70 and he had his foot on the gas when he noticed he was doing 60 and he pressed down on the pedal but to no prevail until he shut off the A/C and he regained the power back and so he got it replaced with a new one. So I definitely would replace it as soon as you can or you will experience it like my dad experienced it.

I have a 1985 oldsmobile toronado and i was driving it all day yesterday and now diz moroning im trying to start it and it wont start for nothing i pump the gas, spray carburetor cleaner on it and it

If it won't start, then pumping the gas and using carb cleaner may make it worse. Carb cleaner is not the same as starting fluid. It will make the engine harder to start. If it's flooded, then pumping the gas will only flood it more. If you need to de-flood, then press the accelerator pedal ALL THE WAY TO THE FLOOR and HOLD it there while cranking. Don't pump it.
Have you looked at the top of the carburetor while someone cranks the engine? Does the choke close when you press the accelerator for the first (and only) time? You state that you replaced the choke; do you mean the electric choke spring? Is it adjusted correctly? You need to know the choke setting for it to work properly.
Then again, it may have nothing to do with the choke. Do you have spark at the plugs? Have you checked the fuel filter?

How to read the engine codes without a Nissan CONSULT or scan tool. (Set ECM in Diagnostic Test Mode II) Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds....

there is a screw on side of the ECM. turn screw counter clockwise all the way and monitor dash board/check engine light on and count the number of flashes on dash board. when you are done turn the screw back into original spot.

I have an issue with a 87 toyota pick up carburetor. Sometimes it doesnt want to start and sometimes it does a friend told me its that diaphram on the front of the carb with the 3 bolts but he could not...

Okay, your freind may be right, that part is called the accelerator pump, it is used for starting the truck, when you pump the gas to start it this pumps a few squirts of gas into the carb. what concerns me is that you hold the gas pedal to the floor to start it, most of the time an internal leaking carb floods the engine and holding the pedal down will let it start, a quick test would be to use a carb cleaner spray and before trying to start the truck hit the gas pedal and see if inside from the top of the carb look and see if you see a squirt of gas spray out, you will need some one to push the gas pedal or you can do it at the carb, if it squirts gas then the accelerator pump may be good and carb may be leaking and need rebuilding but if it doesnt squirt then its bad and then i want you to spray the carb cleaner into the carb and try to start the truck and if its due to the accel pump then after you spray into carb the truck should fire up and run without having to hold the pedal to the floor, if thats the case then replace accel pump if it still doesnt fire until you hold gas down then crab needs rebuilding . good day. hope this is helpful.

'03 Jeep Liberty starts weakly and needs gas pedal to idle

Turning over is what the starter does to the engine can turn an engine over with no spark plugs in it...but you can't start it. Turning over is cranking .....the starter turns (cranks) the engine over (comes from when you had to put a crank in the front of the engine and crank it.)
Does it crank normally but has trouble starting???????
