first, replace the fuel pump with a new unit. the tap tap tap is because youve run the engine too hard while it's cold!!! That is a dry lifter. Basically the rocker arm has no oil between it and it's mount. The simplest solution is to pull the valvecovers, use WD-40 and your fingers. Brake cleaner works too. get the little wheels so they rotate freely. Be careful not to get any in the engine, but you should empty your oil and flush a quart through after replacing the valvecovers using new gaskets.
