Cranks, but no start

I assume this all started after you put the head on it.

If that is the case, then we are going to start with checking the compression and make sure this is okay.

Here is a guide that will help with this:

If compression checks out, then we will need to move on, so here is a guide that will get us further down the path:

Specifically, we need to check the fuel pressure and make sure this is not an issue.

If we have spark and fuel, then based on what was done, compression makes the most sense so let's start with this and go from there.
