Ok folks looking for a little help on my 914 74 914 2.0 car . I have two injectors not firing
2 and 3 . I’ve checked the fuel injection points at the bottom of the dissy they check out . Check with a voltmeter and open and close on both sides . I then checked continuity for wires 21 12 and 22 going to the ecu . I found wires 12 and 22 switch when checking for continuity . The plug and been fixed years ago by looking at the repair. Switching the wires made no difference in injector firing still the same . The efi had just been gone though by a reputable shop that is well know just before I bought the car . The following work was done new intake boots , new injectors , rebuild manifold pressure sensor . Rebuilt ecu , new tigger point for injectors. . I’ve checked all grounds on the rear of the motor. To top this off the fuel pump stopped running but the relays are triggered. I need to check power down at the point . What I’m I missing ? |
