My 2007 Fit ran out of gas. I added gas, but now it only manages to start sometimes. When it does, it runs pretty well, though it (still) needs valve lash adjustment. Do I have a problem with air in the line? How painful is the fix?

 

Hey dude you said you had a problem with start by running out of gas.
so the issue might come in various places like fuel pump, injectors, or even the fuel line itself. The question is how in depth you willing to go i did some diagnostics my self following a video you might want to check it out yourself it was very helpful.
