Fuel pump relay is the most likely cause judging from previous posts, may also fit in with your previous problem. You can check it out by either listening for the pumps running when you turn on the ignition (but they only run for about a second unless the engine is being started or is running) or by temporarily jumping the relevant terminals on the relay base/connector. Terminal 30 is incoming live from battery, 87 goes to pumps, 87V to cold start relay.
Thumping it with the handle of a large screwdriver often effects a short term cure.
Forget about the OVP relay, assuming you car is KE jetronic injection (round distributor with injection pipes connected around the outside) it is unlikley to prevent starting altogether.
