Hi,
Have a look at the ignition control unit. It sits on the left inner fender up close to the firewall. It is mounted on a aluminum plate for heat dissapation as it is solid state circuitry. These can cause missfires, no start situations. Usually once the car is warmed up hence the aluminum plate. This sound a lot like your problem and most often overlooked. There is no dist. on these cars as the rotor is mounted directly to the camshaft. No vacumn advance. Both the advance and timing curve are contolled through the ECM. If the o ring seals are bad on the fule pressure reg. you would see fuel stains around it, I have a very hard time believing that this would be the problem. THis sounds very much like an electrical miss, not fuel related. This problem will not set any codes.
Hope this helps, Rick
