Edit>> yeah it is a big headache for sure. I hooked up a multimeter to my engine coolant temp sensor yesterday and it went from .42 (20kohms) to .45 (20kohms) and then went blank. Don't know if I can trust hf unit haha. Bought expensive 9v last night for my new and better mm and we'll see how that goes.

Is hf unit Harbor Freight? I have a nice Fluke meter here but as it's not mine I will not use it so I just bought a $10 volt/ohm meter from Harbor Freight and it's garbage. When you put it on the 200 ohm scale and touch the probes it will read either 1.5 ohms or infinite. I once bought a compression gauge there because unlike mine it had adapters for a 10 mm spark plug hole. I was pretty quick to condemn the old Honda 90 engine until I tried it in one of my vehicles and found it only read 1/2 of what my old American made Sun unit read. I'm not a big fan of Harbor Freight tools, particularly diagnostic.

Yeah, harbor freight.. agreed, some things are better left on the shelf. I've never actually paid for one of their cheap units.. always the freebie

Never had a problem with their centech unit that I didn't cause. I'm talking about the 30 dollar one, not the freebie.

Waltham, those compression numbers are low... Very low. A good healthy engine should be 180+ warm. 150 is a minimum for anything to be considered running ok. That in mind, Skippy is running ok with #3 at only 60 psi. Down on power, but nothing like what you describe. You might want to do a leak down test...

It was two weak injectors Arty...

Same circuit, or one on each?

1&3 last night, changed #4 a month ago. Both circuits have solid voltage

I will run all these questions by my mechanic in the morning, I asked if the injectors had been looked into when they were diagnosing the problem after the first pump replacement. They answered yes and I did not question further, since I admittedly don't know the little components involved in so many of these parts. I will ask that the screens be checked if they weren't already. The o2 sensor has not been replaced, and again I dunno for sure if that was something my mechanic looked into inbetween the first and second pump replacement. I do know that they were working for hours checking the "tune up" things wires, plugs etc. before arriving at the fuel pump again.

Any word? My festy was doing a lot of the things yours was/is.. my b6 ran worse than a b3. I'd pull the injectors and spray both ways with carb cleaner as you quickly actuate the solenoid (injector).

We used a medium size vacuum cap with a tiny hole for the carb cleaner straw hose to go through.

I made my own post. Feel bad I threadjacked elaphox. My mpg went from 20-30 (big range I know) to 38 this weekend. I hope you find some headway on your festy.
