These are always difficult to diagnosis. Assuming you have a generally good tune on the car, there are some typical issues that can cause your symptoms. Since you are "getting by" for now I would suggest a few simple checks before embarking on a major test or part swap campaign. Check the ignition high-volt start circuit. Primarily the relay mounted on the firewall by the engine compartment light switch. It is often overlooked and if it is not functioning can cause a hard start. Interestingly, the relay does not show in any wiring diagram I've seen either. The circuit does but not the relay. If the ground to the engine for the relay is disconnected or weak the relay will not function and there is no hot spark voltage. So, check this relay and its wiring. Check all the wiring to the coil and the voltage resistor - good connections are important here. Swap out the RPM relay. If you don't have a spare you should have one - These can act up and there are a couple of versions - one being better than the other as you might suspect. See Hervey's web page for an explanation. Run a cleaner in the fuel system. Selecting the right cleaner can be somewhat of a problem because some cleaners may be dangerous to the seals in the fuel system. I recommend Marvel Mystery Oil - the red stuff. I have used this stuff in D's for 20 years and it keeps the fuel system spotless - not to mention the intake valves and ports, etc. - spotless. It can also clean deposits from the internal check valves and improve the seal for a longer fuel pressure leak-down.

I have noticed that whenever the car is parked outside on a semi-hot day (75-85 *F) while I'm at work it will take significant cranking for the engine to catch (7-8 cranks) when I go to drive home. But it does catch and runs just fine after that. However, after the car has spent the night in the garage it will start up just fine in the morning on the first or second crank. I have also noticed that hot starting is fine, just periodic cold-start issues during warmer weather. The hotter the day, the harder the start. I have replaced the fuel accumulator, the fuel pump with a new check valve and have verified that the cold-start valve is functioning as well as the thermal time switch.
