Crank Position Sensor on 8.1L? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Has anyone here replaced this?

We bought a 2002 8.1L Suburban and it has started to stall... I searched online and found that a bad crank position sensor can cause this and is common on this motor. Unfortunately, I'm finding conflicting info on where it is located... one said rear - back of block, near tranny... other said near the EGR by a fuel line. So, I'm hoping someone here has the right info.

Also, where is the best place to get a new one? The dealer or a parts store?
