The starter spins but does not turn motor. Checked codes showed crank shaft position sensor two knock sensors and misfire on cylinders 1, 3 and 4. Replaced crankshaft position sensor still no change.

Can I ask if you can see the engine cranking over or is the starter spinning and the engine just sits there? Please let me know.

Yes, the motor turns and has a backfire every once in a while.

Okay, lets start by doing a compression test to help us see if you have a mechanical problem or not, or you can make a quick video of the engine cranking over which I can tell from that you can upload it in your response. Here is a guide to help with the compression test:

This link can help as well:

Please run down these guides and report back.

Cheers, Ken
