no start is no good
Ok, starts on either. I am assuming spark and timing is good. (you might want to check) Check voltage at the coil AND at the fuel pump while someone else cranks the car. Now, IF the fuel pump is active during cranking ( it is getting good voltage and pumping when you crank the engine) you would next want to check the fuel pressure. If no pressure gage is avail...crack a line and see if the fuel is flowing. (not exact, but it will give you an idea) IF you have fuel pressure but still no run....get a bosch "noid" and see if the injectors are getting signal.
What I am saying is...you gotta narrow it down from here. No fuel delivery is either no signal or insufficient pressure. And of course, check all the grounds and all conectors to the FI components.
