I was doing something in my engine a few weeks ago and I think I hit a wire for the oil pres gauge, b/c now it doesn't work at all. The reason that I think this is b/c the same thing happened when a coolant hose started leaking, but I took it to the mazda dealer and they fixed both.
So my question is, is there a wire that I could have bumped off somwhere near the spark plug wires, and/or how do I fix it?

 

Either the connection for the oil pressure sender or the black wire with a capacitor connections. Looks like a black little block with a round metal connection. That grounds to the tranny or the firewall.

 

The wire for the oil sender is right by the plug wires. It attached to the end of a saucer looking thing. you probably knocked it off, its extremely easy to do.

My car didnt have the capacitor installed until a few months ago, and the oil gauge still worked.
