Default Major screw up, now I get to buy a new injection pump

So last night I was replacing the seals on my pump. I have a 99.5 golf. I had watched the videos about a week ago. And had apparently forgotten some. I decided to only do the top cover and the quantity adjuster because the other one wasnít leaking. I know, I was doing a half job. My car is at 410,000 miles now and I itís my only car so I didnít want to make it any more complicated than I had to. So when I went to put it back together I didnít think about aligning the QA. Pin in the hole it belongs in. Now it bent the pin. So, now Iím looking for a cheap truck for the mean time to get to work and what is a good but cheap way to fix this? I feel like the car isnít worth the money of a new pump. Can I possibly change just the QA? Should I look for a used pump from here? Thank you in advance for any help with my screw up.

I have a used ALH 10mm IP, 160k miles for sale. Removed to put a larger IP on. Been stored in diesel since removed. PM me if you're interested...

Try DFIS or internet search for parts, they're not common.
Or get those bits on the bench and see if they can be repaired.

Take your pin or pump over to Diesel Injection Services on 54th and Clay. If anyone has parts, they would. Steve and Rob work the counter, Rob owns a couple Mk4's

Can you remove the pin and bend it back? Your not going to do any more damage than you have and hey maybe it might work.

Try Kirk Blackmore (r90sKirk) in Cedar Springs...right around the block from Grand Rapids.
He is listed in the trusted mechanics thread in TDI 101. He has a bunch of pumps there and may have a few parts on hand.

Some guy the other day said I was too expensive to seal a pump. I said, "thats what you pay to get someone with experience and knows what they're doing".

He wasn't happy with that and found some "illegal alien" to do the work cheaper. Hope it didn't turn out like this one.

Poor "mechanican" and poor "ownership" (like sportsmanship) kill bunches of tdis.

I really dont think anything in the pump is damaged. Is there a way to just replace the QA? I could find a tear down of an older VE pump but not ours. Ive been looking for a newer lower mile TDI from the south. Im not ready to part with my car yet, but really not wanting to put close to $1000 into a car with 410,000 miles on it. I can get fuel to cylinders 1 and 2, but not to 3 and 4.

To swap out the QA you will need a pin release tool or facsimile to detach the N108 valve from the harness connector ...or buy the N108 with the QA.

What makes you think the pin on the QA is bent? If it wasn't in the hole but was hitting the collar it wouldn't have seated on the pump body. It would have been sitting a good 3/8" too high. I don't think the bolts are long enough for you to force it down to bend the pin.

If you missed the hole you might get a runaway or no start.

If you are getting fuel to two cylinders you probably just need to bleed it more and get the QA located properly.

On the VE pump, if the QA pin is not in the hole, the engine will start will it will not accelerate above idle. Does your engine try to accelerate? Just a thought...

it looks bent. I can get a picture tomorrow. it would not start since i have had everything apart. I guess that gives me some hope.

Just a little more detail about what I did. I was planning on doing all three seals. Last minute I got a little intimidated with doing the last one, the pump head. I had sucked all the fuel out if the pump. when I went to put it back together I though I never rotated anything, it should go right back together. well when I sucked the fuel out I moved the collar.

I spent a few hours priming it yesterday, getting every last air bible out. I still can’t get fuel to all the cylinders. I didn’t take it apart yet to get a picture. If I did bend it, which I’m pretty sure I did, but it’s not more than there is adjustment in the QA. I move the QA to compensate. If I manage to get the pin to the right of the collar, the. The cam pushed it and bent it to the left, would there be any pump damage. I moving toward getting a new pump. I’ve been planning on getting a new to me mk4 tdi. They seem to be getting hard to find though! I guess this one mightn’t be worth fixing up. It’s an Arizona car. It’s been in Michigan for 8 years now.
