As I promised, I'm updating everyone after replacing the fuel pressure relay. Checked the coil; good spark. Tried to start with and without the fuel return line hooked to the tank, no difference. With the return line hooked up to the tank, the fuel pump continued to run with the key off until I turned the ignition on/off again. This leads me to think its the fuel relay or more probably the CPU. This is the more likely scenario - the old style computer had a ground problem which affected fuel delivery. Bob's Import service added an additional relay to compensate. Not a clue on the specifics. Plan on calling them. Hope they remember after 5 yrs. Tomorrow I'm going to replace the fuel relay, but the best plan regardless is to eventually replace the CPU. Does anyone have an upgraded one to sell or have a suggestion on where to find one?

Thanks for the help! I'm on my way to a Halloween party. I'll check in later.
