Why would my 92 Oldsmobile Achieva V6 3.3 engine have difficulty starting?

No Ck engine light except when You turn the key over and before it starts. I assume that is to make sure the light is working. I have had different mechanics try to fix this and so far no success. Is there a process of elimination that I can narrow it down to something?

CK FUEL PRESSURE COLD AND WARM. POSSIBLY A FUEL PUMP OR FUEL PRESSURE REGULATOR
