no power on fuse 11 (B230F) 700

posted by  someone claiming to be Jan Klaver on  Sun Apr 27 09:18 CST 2003 [RELATED]

Have some electrical problems with a 1989 740 estate. The engine is a B230F. I appeared that on fuse 11 there is no power. When I borrow power from another fuse (extra wire from fuse 7 to fuse 11) the car runs fine. After replacing the original injection relay still no go. There was a 1347603 which is replaced by a 3523608. According to some experts both relays are the same (?)
I've use the wiring diagrams that I've found at: http://www.autoelectric.ru/auto/volvo/740/1989/740-89.htm
Any ideas?
Jan

What are the last three digits of the ECU?? 561 is the troublesome ECU while the 951 is apparently trouble free and considered a replacement for the 561. I recently had an 89 240 with the 561 fail to start. It would start when I jumpered the intank pump fuse to the main pump fuse. This is consistent with this particular ECU failure. When it fails it no longer grounds the fuelpump relay. Installing a 951 ECU solved the problem.
