2005 chevy 1500 4x4. Will not turn over. Not getting spark. Changed crank shaft sensor still no spark

If your engine will not turn over, is it the battery? A low battery will operate the interior lights but it does not have enough amps to turn over the engine. When you turn the key to the start position, do you hear the starter engage, (sound coming from the starter area) or no sound at all? Why did you change out the crank shaft sensor if you can't turn over the engine? How do you know there is no spark if the engine does not turn over? Conflicting information here or not complete for an accurate suggestion for a fix. Have you tried a jump start? If it starts with a jump start, it very well could be the battery. If the engine does not turn over even with a jump start, it might, just might be the battery or cable connection to the battery. If it turns over with a jump start or new battery, forget checking the starter. I'd check the computer module since the crank sensor has been replaced. When the computers decided to go out, it just goes out without any warning. The engine will turn over though, just not start.
