I've had my Power Ram 50 for a while now, been slowly restoring/customizing it to my tastes. The engine was rebuilt shortly before I purchased it, and only has a bout 10k miles on it. I also recently replaced the head gasket after accidentally over heating it. I had the head checked out, no issues, and I had been driving it for about 7 months with no issues. Ran like a top. I took a weekend trip recently and the truck ran great on the way over, but once I returned I noticed it wasn't idling very nicely. As I continued to drive it day to day it got worse and worse, now it smokes horrendously and has no power.
I recorded a video to show whats up. Any suggestions? Injection pump going out?
