Motronic 4.3 Fault Codes 850

posted by  someone claiming to be John Harris on  Thu Feb 14 02:26 CST 2002 [RELATED]

Found what could be the sensor's common signal earth point.

From underneath with splash guard removed can access earth point next to oil pressure sensor near dip stick tube at front of motor. Its has a reasonobly heavy black wire that enters the harness running across front of block. Have cleaned and rebolted, but still has made no difference.

Maybe its time to test ECU!

Any other suggestions to get back some ingnition spark?
