Volvo 240 1984 LH jetronic 2.0:

So we had to smog this month, and the tech said that the timing was off. I though the timing was 100% computer controlled, but he convinced me to try to rotate the distributor (it was 16BTDC instead of 12BTDC +-2 degrees). Well, I get the timing dialed in and then the car stops starting up. I figured I fried something while messing with the distributor.

After some troubleshooting I find that the system relay is not activating. When I jumper the relay plug (30 & 87 or Red to BN), the car starts up fine. It just appears that there is no ground signal from ECU terminal 21 to the relay terminal 85. I checked everything out that I could think of. With key on, power is present at ECU terminal 18 and System Relay plug at 30 and 86,(power from ignition switch), there is power on ECU terminal 1 (from coil). But no matter what I do the relay plug @85 has no continuity to ground from ECU terminal 21. ECU ground checks out OK *(ECU 25 I believe), but no continuity between ground and ECU terminal 21 with ECU plug disconnected.

Again, when I jumper the system relay the car runs fine, but for some reason the ECU is not activating the system relay when the ignition is turned on. Is there something else that has to happen before the ECU ground the system relay?
