Could this be a faulty relay?

I don't think it could have too much to do with the Megasquirt because it doesn't control the fuel pump.

What else could cause this? I would think maybe a bad FPR but like I said, I clamped the lines and it still cycles on and off. Oh, and when it kicks on I hear fuel just ripping through the rail.

Also, MS DOES control the fuel pump man, or at least it can. It might be because your using the stock wiring for the fuel pump that its acting goofy, idk. I would wire up the fuel pump to MS and see how it works from there.
