The following test is very dangerous. Do not try this if you are going to let the brake go at anytime. YOU MUST HOLD THE BRAKE DOWN WITH YOUR LEFT FOOT 100% OF THE TIME.

OK. Open the hood and turn on the car. Have an assistant stand to the SIDE OF THE ENGINE NOT IN FRONT OF THE CAR. Next, put your foot firmly on the brake with one foot and your second foot on the gas simultaneaouly. Put in gear iff the brake is all the way down. now torque the motor by slowly giving it gas, while you brake NEVER IS UNDONE. Your assitant is looking at you engine to see if it is moving forward and backward erratically. Now torque in reverse gear.

Hold the brake 100% of the time. With the seond foot torque (giving gas) in reverse. You assistant is looking to see if the engine moves erratically.

It sounds like you have a broken engine mount. If a Toyota, there is a "dogbone" looking mount on top of the engine in front of the passenger in the engine compartment. Notice it does not happen when you run lightly, but it noisey when torqued.

Starter clicks and turns slowly. Battery is great replaced starter and still have that problem. 2007 civic lx will not start. 1.8 liter automatic 65k miles maybe relay problem?


Check your + and - connections on the battery. Also check your connections to the starter. Last, a bad cable could be robbing the amps needed before it gets to the starter.

With engine started and foot on brake truck will not come out of park. will come out of park with ignition switch turned to the first notch but engine not running. with ignition switch turned to first...


Sounds like your brake lockout switch is bad. The brake lockout switch on many vehicles is used to prevent accidentally shifting the trans into gear. The fact that you can shift with the key in the ACC position is a dead giveaway. Good luck.

FLYWHEEL MAKES RUBBING NOISE WHEN WARM AND ACCELERATING


You have a grinding noise when it's running or when you try to start it?
There is an inspection cover just behind the oil pan of the engine. If you remove it you can see the teeth on the flywheel. Chances are that the flywheel may still be good and the starter drive (part of starter) may be failing. If so and you leave it that way it will damage the flywheel. On automatic cars it's called a flex plate. And yes if you have a chrysler trans on there the converter may have the ring gear welded on.
