03 Lesabre - Problem Starting
My 2003 Buick LeSabre is having a little bit of a problem, I have had the car for the last 4 years with no issues starting the vehicle. One day out of the blue the vehicle stalled and would not crank after multiple attempts. I waited for about 20 minutes and tried again...BOOM...car cranks on the first try but Check Engine light comes on... I take it to my local auto parts store to troubleshoot the check engine message and it read "Camshaft Position Sensor malfunction", at which I purchased a new sensor to resolve issue. Ironically the vehicle started up as normal for the next few days prior to any repair, check engine light no longer on. 2 days ago the problem resurfaces and I decided to take the vehicle to a local Midas to replace CPS, Midas tech advises that he replaced sensor but vehicle still having issues. What's going on here?!? I did a little research and it may be the Crankshaft sensor or a bad Ignition Control Module...Please help, this problem is pretty annoying!!

RE: 03 Lesabre - Problem Starting
A code for a CPS means the signal is not reaching the computer. Generally that means the CPS is bad but sometimes it's a poor connection between the two or a bad ground somewhere in that same signal path. Most times a GM car will run with a bad CPS so I would suspect the ignition module or the coil is at fault. This is one of those things where it's best to catch it in the act for a proper diagnosis
