I have a 2000 oldsmobile intrigue that i recently replaced the crankshaft sensor on due to the b circuit failing. I now turn the key and sometimes have to cycle it several times to get the motor to start. The motor will not crank at all while i am cycling the ignition. So if anyone has any ideas let me know. I also get a code now for the A circuit on the crankshaft sensor and a camshaft b circuit sensor code. not sure if it has anything to do with replacing the crankshaft sensor.
