Just grounded the manifold to the frame and about to take it for a drive. I'll still take the switches just in case! I'll report back to see if grounding the manifold to frame helped. The ground for the sending unit was there and it has been working fine. The other ground just comes out of the end of the wiring harness, so I'm not sure what it grounds.

No change with the grounded manifold. Still no green light.

This is getting nutz. I would have to read the whole thread again but have you checked the relays on those timer cards?

Yup, replaced both relays on the timer card.

I pulled the stock diesel pump fuse and checked the "WVO" pressure even though it's diesel in the tank. Guage was only reading a steady 9-10 PSI! I adjusted the fuel pressure regulator all the way in, all the way out, and where it "should" be at the 2.5 turns in from all the way clockwise (in) with no change at all-stayed at a steady 9.5ish PSI. Does this mean the pump is shot? Fuel Pressure Regulator is shot?
I'm emailing Jay to get his help as well, and I'll post his advice and progress here.

Are you running SVO, SVO+DIESEL, or Straight diesel in your tank?

Straight diesel for now. Didn't want to put WVO in the tank in case the purge didn't work in the cold weather. I have plenty of filtered WVO ready to use though!

Sorry, should have added this.

Do you have a Scorpion pump, or the FASS pump? Old Scorpions were known to have problems pumping D2 as it's thinner than SVO.

Purge should still work.

It's a scorpion pump. Jay mention that about "1 in 20" didn't like to pump D2 very well. He also said that those pumps usually still push 40-50 PSI.
Does that mean the pumps still pump WVO just fine? Maybe I should put WVO in the tank?

I pulled the fuel hose from the V3 to the engine tee and tested it. Fuel started dripping out as soon as the ignition switch was turned to "accessory on", and when the veggie switch was flipped to manual on, the diesel came out with a lot of volume. Probably got about 20 oz of fuel in a few seconds. Seems normal. The pump is making a slightly gravelly noise.
I pulled the tank fittings and they were pretty plugged up-looked like polymerized oil that was thick and nasty. Pulled all of the fittings and have them soaking in Super Clean to de-gunk them. The fuel pickup was really hard to unscrew, and found it it's all stripped out. Messed up the opening where the hose barb threads in. Fuel pickup looked clean otherwise. Thinking about JB Welding the threads back in, unless you recommend another method!
So, questions for now-could the plugged vent fitting and fuel return fitting cause the problems I've been having? What can I do to get rid of the gravelly noise? Anything else to test from here?
