I have the truck listed above c1500 4.3 v6. I was driving it and it backfired the stalled and wouldn't crank again. It has no spark at all. I've changed the spark plugs, Distributer cap, wires, rotor, ignition coil, and ignition control module. It still won't crank and I'm still not getting and spark. I've tried to locate the crankshaft position sensor but can't locate it. Help.

I would remove the distributor cap and have a helper crank the engine over the make sure the rotor is turning. Next use a test light to see if there is power at the coil with the key on. (pink wire). Here is a guide to help you:
