Question about 1988 Buick Century

1 Answer

Crank position sensor bad

I have installed a crank position sensor twice on my 88 century 3.8 engine. aAfter replacing the sensor the car will start and run fine. After turning car off it will not start. Check the sensor and found bad. I have installed the sensor with the proper clearance to the pick up fins and the sensor does not show any damage of contact with the fins. I have done this twice and both time sensors bad after car runs. could there be something makeing the sensor fail like high voltage? What voltage reading should i get at the sensor plug. The manual i have tells me to OHM the sensor to check to see if it is bad and by doing this my sensor is bad.

Will crankshaft sensor make 2003 Buick century with 3100 (3.1) engine not crank?

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.

1994 Buick Century Not Turning Over

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.

1989 olds regal 88 3.8 v-6 car runs great but while driving it will stall out changed coil ,egr valve and fuel pump . seems to be mainly when its warm

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 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.. ,

1987 Buick Century Limited V-6 engine w/ac. Engine cranks but won't start. Instrument panel light shows "Service Engine Soon". Also light shows "Oil Choke". And light shows picture of battery.

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.
