Someone had ROUNDED off the nut portion of the solenoid!
I put the 24mm open wrench on, it was too large to turn. (it will strip or round off even more if I tried!)
I had removed the bracket and injector lines to have more room to work with. Super tighten a large Vise Grip, and still seems to (going to) slip, and the solenoid won't budge! I sprayed with a lot of penetrating oil and even use torch to heat and cool the materials to remove the solenoid, but without any luck!
Finally, and lucky I had the Triangle wrench for the injection pump.
I removed the top cover for the injection pump (which was held down by three torx and that "triangle" bolt. But even after I removed the pump cover, I still don't have enough room to put any tool on the solenoid.
So, I remove another threee (torx) bolts to remove top body of the injection pump! (I hope I didn't change any setting on the pump? At least it didn't look like it? The bottom of that section only have a rod on the bottom, and no adjectment or any springs of mechanical device I could see?)
Anyway, after all that. I was able to put the 24mm open wrech on the solenoid in a different position (better surfaces rather the rounded off surface for grip). and got the Solenoid of!
Now! after I pulled the solenoid out of the pump. The little tinny srping is still inside of the Solenoid, but the plunger and the O-ring is still in the Pump?
My questions: (this is for 1998 A3 Jetta 1Z/AHU engine)
1) IS the O-ring suppose to be on the body of the solenoid?
or if it is okay sitting there between in the pump and solenoid to make the seal between the two?
2) Is the plunger part of the solenoid? because mine came apart.
3) Any issues with my injection pump now, since I had taken to top cover and top half apart?
Any help will be appriciated!
thanks!
