Hey so I recently purchased this car with the only information being that the lower timing chain needs to be replaced. Before pulling the motor apart we decided to try and start it just to see if it needed a new lower timing chain. Turns out that it's not broken and when we crank it, we get fuel and pretty sure we get spark. The car backfires very badly too. My guess is that the timing skipped because the previous owner said the car just completely died when he was driving and it wouldn't start back up. Here's a video of us trying to start it, any help is appreciated. Thanks

bump could use any suggestions or ideas guys. Really appreciate it. Even someone flaming would be better than complete silence. I have tried searching around and have some ideas but to no avail.

If timing jump/chain issues happened while driving there is no telling how much damage internally could have happened.

correct me if im wrong, but isnt almost impossible for a chain to skip/jump teeth?
OP, if youre unsure, the best bet is probably just to re-time it. also wouldnt hurt to check the codes before you tear it all apart.
