Chevrolet Lumina Problems

Crankshaft Position Sensor, Ignition/Powertrain Control Module May Fail on Chevrolet Lumina

Problem Description and Possible Solution

The crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.

Not sure if this is my problem. The security and air bag lights light up but the car will not start. Any help?
I got a check engine light showing up that didn't go away. Even after I reset the ECU it came back on. The code was p0340. I figured it was just the sensor itself due to the fact that a visual inspection proved benign and the lumina was getting significantly worse gas mileage. I purchased a new sensor from Amazon for around $25 and the replaced it. Worked like a charm! The hardest part of the job was moving the power steering pump out of the way to access the bolt that holds the sensor on place. I had to pry it with a large wrench to move it up and out out the way. Also, a magnetic telescoping arm is quite useful for grabbing and placing bolts.
the chevrolet lumina is a oil leak on the crankshaft think the crankshaft position sensor having a hard time to start the car.on the four the car start.
