If you did the plug swap thing then you proved out all problems except 
the reason for not maintaining system rest pressure. For some reason 
you are not holding system rest pressure. You need to determine what 
element in the fuel system is letting the pressure down. Refer to 
D:01:14. There could be a fuel leak, bad check valve on the fuel pump, 
bad fuel accumulater, or the fuel distributer.Since you said you 
replaced most of these items the only obvious choices are either leaks 
or the fuel distributer. I reccomend getting a fuel pressure gauge 
setup and trying to narrow this down as it is possible in changing 
some parts one of them may be defective as even new parts can either 
be bad or go bad. A slight leak at the fuel pump may go unnoticed but 
it allows the system rest pressure to drop so you cannot tolerate ANY 
leaks anywhere in the fuel system. Never "tweak" the mixture screw in 
the metering unit. Once you touch it it can only be properly set on an 
analyzer and besides that won't solve the problem. Be careful working 
on fuel injection systems because if you have even a minor leak it can 
be invisible but the fuel comes out and vaporizes immediatly and if 
ignited becomes a miniature blowtorch. Fuel injection systems usually 
operate at high pressures as opposed to the older carbureated systems 
which only run at about 5 psi.
