Apparently a commonly overlooked cause of black smoke lies in the gaskets on the EGR valve and intake manifold. So the smoke problem is now cleared up. I have 20" of vacuum going to all the selenoids. They all work when wired directly to the battery. But I have no vacuum going to the EGR and WG. A new ECM was put in. When ordering the part we found out that it has a upgrade. So it comes down to a ground wire somewhere between the ECM and selenoids I guess. Has anyone had this problem? How is it wired? Is there a single wire that splits to ground the selenoids or are they seperate comming directly from ECM going to individual selenoids?

Measure the voltage at the plugs that go into the solenoid. You should read 12V at idle. These wires can be broken inside, you won't notice it and it doesn't always trigger the SES light.

No vacuum on the EGR valve keeps the valve closed which is a good thing :)

Cut off the wires to the WG solenoid as close to where they come out of the harness as you can, get a new plug for the WG solenoid (plugs on the solenoids are different) with an adequate length of wire on it and connect the new wires to the ends of the old ones where they come out of the harness. Strengthen the new wires with adhesive tape and fix them with wire straps to protect them from vibration.

It's very helpfull to use a new plug because the wires can break just where they go into the plug, and then you'll have a hard time when trying to fix that. They can break several times within the short length of the wire that comes out the harness --- I had to fix mine two or three times.

If that still doesn't help, you might have a short ground, but I'd expect that to trigger the SES light. You'll trigger it when you take the plugs off the solenoids.

If you get 12V on the plug but no vacuum, the solenoid can be sticky. Try spraying WD40 through it, but that's said to fix it only temporary, if at all. You'll need a new solenoid then. But since you veryfied that they work, it's more likely broken wires.
