You may want to check the amp draw on the 2 fuel pumps both the exterior pump at fuse # 6 and the in-tank pump at fuse # 4. While the car is running,take the fuse out and place the amp meter leads on the metal fuse holders to read the amp draw on each one. Start the car 1st to build up a little fuel line pressure so the car will run while you get the leads onto the fuse holders connections. The correct readings for the in tank pump should be 1-2 amps for in tank pump and 9.5 amps for the main exterior pump for the K-Jet system. 3-4 amps for the in-tank pump and 6.5 amps for the main exterior pump in th LH-Jet system. If you have a Bently 240 Repair Manual (VERY WORTH THE INVESTIMENT) you can read further about the procedures.
One other thing I did to clean up a starting problem was to put a full bottle of "RED LINE" Fuel Injector Cleaner in a full tank of gas. It really worked!! and is worth a try.
