You could try -
put engine a Little Past #1 TDC
remove #1 Inj Line from back of pump
wad up a piece of paper or bubblegum wrapper that fits loosely snug in the delivery valve
rotate engine back around - if the "plug" pops out after 1 engine revolution - pump is 180 out.
if it takes 2 engine revolutions to pop the plug - its in spec.
Might should put power to the fuel solenoid when doing the test (key on).

Owwwoooo I like that test. I would just run a jumper rather than key on though.

So what in the pump would be 180 degrees out? isn't there a woodruff key? Anywho I put the updated injection pump pulley on the older pump because the one that came with it was cracked. I know the old pulleys have 2 holes, so your saying if I put the 2 hole pulley on, rotate 180 degrees and problem solved?
You know it is entirely 100% possible that this could be the issue.. unfortunately, nobody is perfect
.
Worked out perfectly that this picture shows everything I want to explain
lol. The yellow is the back side of a cam plate and a distributor. The red is the relation between the cam plate and the main shaft. The key idea is the pin and slot of the distributor and cam plate need to line up with the key way in the main shaft.
So as can be seen in the first grungy pump photo and the red in the second photo, there are two spots for the cam plates identical "fingers" to intersect the pumps shaft. This can obviously only be put in two ways, the right way and 180* out, the opposite way. From there it is a pin on the back of the cam plate and a corresponding slot in the distributor for said pin to go in. As can be seen by the yellow in the second picture.

Yeh, you gotta get the pump back into synch now. (180*)
To keep things in perspectives and less complex - you really need an old style inj pulley with 2 lock holes. And make a new alignment paint mark on rim of pulley.
If you use the newer 1 holer - and time with #4 - you won't be able to use the cam lock slide to set up all the initials. You can overcome this - but it gets things way more complex - and probably introduces higher chances for less accuracy too.

Thats a really fair price for a brand new VW Sprocket.
Good Find
I agree on the godsend of this forum and the info shared/pooled.
And lets be thankful there even is such thing as a 2 hole sprocket.
The saving grace on this deal

Thats a promising note.
At least you actually received the sprocket - and its correct.
Hope all goes well with the big re-gig this weekend.

The pump was out 180. I turned the key and it started instantly with no smoke at all.

Glad you got it to go. But this is a little disturbing:
The pump was resealed by a fellow member on this board. Ooopsie. Have to fix that the next time it goes to leaking. Or did you just put a mark on the new pulley on what would be the bottom side?
So How well does it run?

I marked a new timing mark on the new pulley and called it a day. It runs really good now that the timing is not off. I cannot believe it even ran with the pump 180 out. I was getting worried for a bit that by some off chance I wrecked my engine. All is good now

Sounds like a winner Sarge.
It is wild how these rascals can still run sometimes.
I guess we don't get to start calling Jeremy, 8V of Prothery yet tho. lol
He had it all the way apart, and back together, and it runs fine now.
Maybe he needs to go be Prothe's new shop supervisor.
