1978 BMW 633 csi s
I have been arm twisted into helping a friend with a cold start problem. This engine has the typical Bosch cold start injector stuck right in the middle of the intake plenum. So far, it looks like all the basics are covered. I have fuel pressure at the injector, (Cold). And, I have been able to unplug the 2wire connector and apply battery voltage to the injector and observe a proper spray pattern.
My question is, where is the relay, fuse or other control system timer located. Is this tied into the ECT sensor or, does this have a separate timer and control system? My noid light says there is no voltage at the injector at cold startup.
have the same problem?
