The gas pedal does not work

Sounds like it's time to replace fuel filter, or possibly a bad fuel pump. I'm uncertain why the gas pedal would be hard to push as it most likely isn't a cabled type on that new of a vehicle, but you can check by looking at the top of the pedal itself to see if there is a cable and if it's possibly frayed.

Look for where the throttle cable connects at the throttle body. If you can move the throttle plate here and get the engine to respond, then the cable is either broken or disconnected at one end or the other. Any other situation doesn't seem likely.

Check the timing sounds like its more of same problem mine had at one time

I will list several things it could be first bad throttle position sensor,need to hook up diagnostic scanner to verify.2nd possible fuel pump not putting up enough pressure when this happens generally when you push the accelerator pedal the car will die,now if you have a throttle cable still for the accelerator pedal the cable could have broken or came off on top of the engine you can see it .is it turbo charged bad turbo can cause this.lastly the convertor could be plugged which cause the exhaust to be come restricted so the engine cant rev up ,you will hjere like a hissing sound when you try to rev up or put your hand at the end of the tailpipe see if it has good flow out the tailpipe

Not quite everything is fine.
Is the check engine light on ?
When you push on the gas pedal, does the engine speed change ?
Can you rev up the engine in park ?
What have you checked so far ?

first off.... does the engine over rev on its own? or only after you press the gas pedal?
does your vehicle have a throttle body that is electronic or cable actuated?..if electronic and revs on own could be one of two issues 1) throttle body itself 2)throttle pedal switch on gas pedal)
if cable and revs after pushing gas pedal ..either there is too much carbon built up on the throttle plate or the throttle cable has begun to fail.. remove the intake tube from the air cleaner to the throttle body and inspect

It sounds like the gas control lever under the hood may be sticking a little and not retracting fully to idle.Open your hood and have someone start your car.When they give it some gas you should see the actuator move which has a cable attached,probably located at the end of the fuel injectors on the driver side.It should be pretty noticeable as about the only moving mechanism when the gas pedal is pushed.Usually pushing the gas pedal makes the lever move toward the driver.Once you have found it,push down on it in the opposite direction as giving gas to see if the revs decrease back closer to idle.If it does,WD-40 on the hinge where it pivots may help.Spray it,rev it a couple times and check.Even if it works on the first try,do it a couple more times.If this does not work,please reply back and I will get an auto link to see what you posted. Good luck! Greg

Is there somthing hitting the gas pedal, like the floor mat? Or maybe something under the dash came loose and is getting caught under the brake pedal and pushing on the gas. Put the shifter in neutral if you get into a situation where going to hit something or someone. The engine has a rev limiter, to prevent it from over reving.

have you tried getting under the hood and moving the throttle by hand. maybe the line is disconected or broke.

is the check engine light on?? you most likely have a problem with the throttle assembly. It is electronic, not cable driven, so that's why you can rev it. Nissan has had some problems with those. Normaly code P0507 ICS system comes up. But I don't know if your check engine light is on, but it should be, if throttle failed. There is also a switch (electronic) by the gas pedal, which sends all the signals to ECM to be processed and then to the throttle assembly. But those switches (by gas pedal) have been bulletproof. So I would be looking a the throttle asembly again. Good luck.
