I recently purchased a 6.5TD. Towed it home, replaced the PMD, and now it runs. I noticed that there is no pressure on the wategate linkage and that it moves freely when the engine is running. I have good vacuum to the WG sol and the solenoid works when I ground the yellow wire, which the ecm should do. Does this mean that the ecm is bad? Is there anything else that would make the ecm want to leave the WG sol off? Any help would be great. Thanks.
