[QUOTE="cloudbuster, post: 568720, member: 6653"] Sorry to hear about your grandpa's E32 issue. Not familiar with the M30 engine, but it should be quite similar to the M60. You did mention that the injectors are not pulsing? It is supposed to be turned on by the ECM on a normal condition. The pulse voltage is normally in the region of 0.3 to 1.0 VDC and it should be measured only using a digital voltmeter / multimeter. An analog unit would damage the ECM due to the loading current. If the voltage is indeed missing, possible culprit could be the DME relay or the electrical circuit around it. Good luck and hopefully, you manage to get the classic ride back on its' feet again soon. [/QUOTE]
