1991 740 Turbo wagon, Car will crank but will not start. Receive only initial spark from coil, if you turn the key to the farthest position before cranking.No spark during cranking. performed diagnostics, found no code (1-1-1)only. fuel pump loads when key is turned and fuel pressure is good. I have tried a different coil, coil wire, power stage module, checked all wiring, checked temp sensor, & knock sensor, I have not replaced ECU yet!! Please Help I don't know where to go from here. Should have stuck with my old 1984 240 wagon, she never broke down or left me stranded after over 300,000 mi. Two 740's later both have been nothing but trouble.
