Compression Test

So I want to do a compression test, but I have no manual or owners manual. Does anybody know where the fuse for the fuel pump relay is?

Im thinking its the valves or a broken piston ring. Theres no oil in the coolant and vise versa and the compression didnt go up when i put oil in the cylinder. Im going to take the valve cover off and see whats going on.
Does anybody have a beefed up valve train or does everybody just use the stock stuff in turbo and built motors?

Usually I'd go with new rocker arms for any build. That is a main problem with the m20, is the breaking rockers issue. If I were to build any sort of 'hot' m20 motor, I'd have to budget in Billet rockers. For higher RPM applications and/or more agressive cam lifts, I would want to look into different rate valve springs too.
