Like many problems on a 25 year old car, this can be the culmination of many small things. How old are the spark plugs and what are they gapped at? Are you getting a good pattern out of the fuel injectors? Have you ever cleaned out the fuel tank? Replaced the fuel or air filters? If the accumulator is origional it should be replaced just because it IS 25 years old. Is there anything in the hot start relay plug? There shouldn't be. The pressures are to be checked with the motor NOT running, just the fuel pump (refer to D:02:02). The Primary Pressure is a touch low but should not be a problem. The Control Pressure sounds OK if the temperature of the Control Pressure Regulator is around 104 F or higher (as per Fig 17 on D:02:01. The Rest Pressure is NG. Your choices are the accumulator, the fuel pump check valve, and the Primary Pressure Regulator (or a leak which is VERY dangerous). I am guessing but the Primary Pressure and the Control Pressure are probably alright if you read them with the motor off and the fuel pump running. Look at Fig 4 D:01:06. It shows the Primary Pressure circuit. When you shut the motor down it is where the Rest Pressure is held and maintained by the accumulator. It can be lost through: the fuel pump check valve the accumulator the Primary Pressure regulator Any leakage in the plumbing and connections between (also leaky injectors, cold start valve, sticky plunger).
