Hello Everybody,

Have a no-start on a 1987 740 turbo, LH-Jetronic 2.2, B230 FT. No spark. Narrowed it down to Power Stage and its feed. Got 0.12 VDC between pin 5 & ground for the Power Stage feed at ignition "Start," with R/W wire at #1 and blue wire at #15 on ignition coil terminals disconnected. Proper voltage is 2 VDC.

Seems to me that it may be an ignition ECU problem. Any other tests I should run? What are your opinions?

Also, if I need to replace an ignition ECU, who can you recommend? Seems like brand new IECUs are out of sight---over $1000. Any remanufacturers with a stellar reputation?

Thanks.
