Crank position sensor bad

> harmonica

Really? Accordion? Clavier? Harpsichord?

How old is the battery?
Clean the posts on the battery.

Crank sensor only tells the ignition modual what position the motor is in. If it's not cranking you may have a starter solenoid or starter going bad, bad battery, or other electrical issue, could even be a bad ignition switch.

Can position sensor, maybe, or it might be called a pick-up coil. This sensor is needed along with crank position sensor for computer to determine spark timing.
When you get it started, and if you still have the up and down idle, check for an intake manifold leak.

Pump or injectors may be bad .

autozone advance auto a transmission shop will attach a dianostic machine tell you witch sensor my need to be replace possible o2 sensor

REPLACE THE ASD RELAY FOR A NEW ONE= ASD RELAY COMANDS THE ECM AND MANY OTHERS COMPONENTS THE COST OF THE RELAY IS ABOUT $20.00 IS LOCATED IN THE ENGINE COMPARMENT FUSE BOX AND RELAYS

Did you replace the crank sensor that is in the engine block between the engine and transmission? it has two and the one by the pulley hardly ever goes bad.

I would believe the problem lies with the CRANK POSITION SENSOR. The computer relies on that sensor to advance the timing when the engine is cold, once the engine warms up, the computer will ****** the timing and then the timing will be set in relation to the THROTTLE POSITION SENSOR. The crank position sensor costs aroung 30 to 40 dollars. But to have it installed will cost probably around $300...maybe more. To install the CPS you will need to jack up the front of the car, remove the passenger side front tire, remove the plastic splash guards, remove the serpintine belt, remove the harmonic balancer with a special puller designed for that type of engine, then finally, remove two little bolts holding on the sensor and replace it with a new one...........it all sounds pretty easy and straight forward, but really there is not too much room for tool movement and your body will be in an awkward position most of the time. I can do this job in about an hour and a half only because I have done it so many times and know exactly which tools are best suited for each particular bolt and the whole process, I would say it is a 3 hour job if you are very mechanically inclined or a 5 hour job for the first timer.. ,

It takes less than an hour. Removal & Installation

1. Disconnect the negative battery cable.
   
2. Raise and safely support the vehicle. Remove the right front wheel and tire assembly.
   
3. Remove the right inner fender access cover/splash shield.
   
4. Detach the electrical connector from the CMP sensor.
   
5. Unfasten the retaining screw, then remove the CMP sensor.

To install:

1. Install the CMP sensor, and install the retaining screw. Tighten the screw 35-53 inch lbs. (4-6 Nm).
   
2. Attach the electrical connector to the CMP sensor.
   
3. Install the right inner splash shield/fender access cover.
   
4. Install the right front wheel and tire assembly, then carefully lower the vehicle.
   
5. Connect the negative battery cable.
   

I took my car to my mechanic. He did a diagnostic circuit test on the engine and then replaced the distributer ignition module and camshaft and crankshaft position sensors.
