Car wouldnt crank. Had to get another set
One of the crankshaft sensor doesn't work
I ordered and installed these two new sensors and the car would not start at all. Prior to installation the car was throwing a code for the sensors and had begun to crank longer than usual prior to starting so I ordered these replacements. After installing the car would not start at all. I put the old sensors back in and it ran so I returned the parts from 1-A for a refund. I ended up getting replacements from my local parts store. Have had good luck in the past with 1-A but i gotta say give these a pass.
Each time I am in need of a part 1A-Auto is where I shop. Best prices, quick and reliable and delivery is there always when it says.
My 2002 Cadillac did not like this set, I had to buy cadillac original parts.
