I just got two ECU's online for my 740, tried them both, but my 740 still doesn't work. I have a 1987 740 sedan (no turbo) B230F. I replaced the wiring harness, checked the fuel rail leading to the injectors after checking pumps and pump relay and the lines are pressurized with gas. I put some fuel in the intake and she fired right up then died. So my ignition is working and there's fuel heading to the injectors. However, I pulled the plugs and they were dry after cranking the engine, so I am thinking that I'm having an injector problem. I connected the two large wires in the radio control relay and still no go. I tried installing a Jetronic 511 and 544 ECU, still no go. Could the ignition control in the driver side fender by the headlights have something to do with it? Any ideas? I am stumped and need help.
Thanks a ton.
John
