On passenger side there are two relays one is radio suppression relay that runs the injectors. They are exactly the same. Switch them and if it starts there is your problem. I have a 1990 740gl wagon and a 1990 760 turbo wagon. If that doesn't solve the issue, check you fuel pump relay behind ash tray where fuses are located. Fuel pump relay is second one back on left hand side. Usually tall and white.
