good afternoon my name is ***** ***** I will assist

under the intake plenium is what is called a spyder assembly which contains the fuel injectors and the fuel pressure regulator. the regulator is common for leaking causing hard start, run rich when starts and then clears up. a fuel pump pressure test will confirm if it is bad but most likely that is what you are looking for.
