Hey guys just wondering what you all think this could be.

I just installed my fuel pressure gauge and i went to turn the ignition into second position to prime the system. It primed but then when I went to prime it once more nothing happened. Also the power seats don't work on the drivers side. I'm thinking it could be a faulty ground but wanted to get your opinion. What do you guys think?

 

Check your fuse.

 

resolved: bad ground.
