The entire timing chain set was replaced. Car started once it was back together, but it was very loud. The person that fixed it drove it down the road, comes back turns car off now it won't start again.

Hi,

When you say it was very loud, was it a knocking sound, or rapping noise, or how would you best describe it?

Also, when you try starting it, does the engine sound normal? For example, does it seem to turn faster or slower than usual?

Let me know. If it was making a lot of noise, I'm concerned the timing wasn't correctly adjusted. If you can, record it cranking and upload it for me to hear. Hopefully, I will recognize what is happening.

Take care and I'll watch for your reply.
