Electronic Fuel Injection Control Unit #561 Defect 700 89

posted by  someone claiming to be Bill Bauer, formerly Michael Bauer on  Sun May 20 12:17 CST 2001 [RELATED]

Hello

We have been told that the above unit has failed in great numbers. I am not sure if the #561 is specific to 89 740's or if other applications were affected. A repair shop familiar with the problem has explained the emergency fix is grounding the fuel pump relay lead going to the fuse box. Has anyone ever attempted opening up the #561 unit to understand what the fault is and why so many units were affected. Weird enough we also had a different 89 740 with unit #557 which failed within the same month. Thanks in advance. See ya Bill
