car wont turn over

installed some oil pressure gauges into my igniton source and now nothing. fuel pump kicks but wont start. all relays work and fuses but it does sometime kick the ignition fuse any idea's is there another relay somewhere???

I have no idea what the hell you are trying to say. You need to type so we can read it.

You installed an oil pressure gauge, or multiple ones from what I can tell. You used the ignition as a power source? And now the car wont turn over? Or it will turn over but not crank?
