The gray square one is a relay, you can swap them out with eachother just make sure the terminals are matched up correctly

Default Air lock

Any chance you got air in your fuel lines ? If so crack the bleed screw next to primer and pump until fuel comes out. I’m having the same issue as we speak and eventually burnt the starter out..

This was back in 2009. And this was the LLY. What happened, was one of the injectors hung open. It wasn't allowing it to build enough pressure to start I guess. Anyhow, we used starting fluid to get it fired up, and it ran. Replace the injectors, and that was it.
