Cranks but doesn't start. Checked fuel relay, fuse. Coils and plugs have spark. Only code was po135 and replaced O2 sensor. Now no codes. Sprayed intake with starter fluid and didn't change anything.

Welcome to 2CarPros.

If you tried starting fluid with no result, then there is no spark to the plugs or a timing issue. Take a look through this link. It discusses the most common reasons for a crank no start.

What I really need you to check for is spark. Here is a link that shows how it is done:

Do this and let me know the results.

Take care,
Joe
