Question about 1987 Oldsmobile Delta 88
The car has been tested and the crankshaft senor has been diagnosed as the problem. This is my sons car and he does not have the money to take it in and get it repaired.
There are two crankshaft sensors located at the edge of the harmonic balancer. That's the large wheel coming out of the engine, passenger side, the wheel that powers the serpentine belt. One sensor is the crankshaft position sensor and the other is... I forget... crankshaft angle sensor or something. I replaced both on my car. I don't know wich one is your problem. When you buy a sensor, get the one with the mounting bracket already attached. They had problems with the sensor getting damaged from being adjusted wrong. Having the bracket already attached gives you the right adjustment.
Remove the serpentine belt. (It has a tensioner wheel. When that is moved, the belt becomes loose and can be removed.) With an 18 mm wrench, turn the crankshaft until one of the openings in the metal fin is at the sensor, giving a space where the sensor can be removed. One sensor is reachable from the top, but it is real hard to see. The other is reachable from underneath. My guess is, the lower one is you problem only because my lower one failed twice and the upper one only once. Your son has to crawl underneath, unhook the wire from the sensor, and unbolt the sensor mounting bracket. Put the new one in. Keep your fingers crossed.
