uhh so i ran it for about two minutes and then it stuttered and died. It got alarmingly warm for how short a time it ran for. The water light was flashing and so was the oil light? but there was no buzzer for low pressure - does that make any sense?
I thought it died because i have the pump loose for timing and it sounded like it was getting more and more retard but it just shook to a stop. the intermediate shaft turns so it's not siezed or anything. How do you know if the oil pump is turning? i fear that the vacuum pump from the 1.6 isn't long enough to engage the shaft of the oil pump...
now its really hard to turn over but it will go with some effort

I believe the gear is different on the vac. pump for the 1.9l.
I think the 1.9 gear is larger I'm sure someone will correct me if I am wrong. The intermediate shaft may not be driving that "new" oil pump.

pull the oil pressure sender, then turn the motor by hand, oil should juice out.

The pump isn't new.
i pulled the vac pump and compared the 1.6 one i cleaned up to the 1.9 one. I would use the 1.9 pump but the fitting for the vac line has broken off.
They have very slight differences. the 1.6 has more gear area which makes the 1.9 look like its longer.
i took off the belt, cam cover, cam, vacuum pump and had a look at everything. it was all really really hot. The IM shaft turns fine, the cam turned fine, the injection pump/waterpump/alternator spin freely.
i tried turning the crank by hand and it gave a nasty machining sound so i stopped immediately.
I was starting the think that the crank had been starved of oil which would be a really bad thing so i triple checked the oil level (its hard to see because its still perfectly clear oil) and got out my trusty 1/4 drive to trill bit thing and fired a 12mm deep socket onto three extensions and then to my drill. i gave the oil pump a good hit with the drill and oil came juicing out of the seats of the cam (and down the side of the block). at this point i quicky put the cam with its seal back in and tightened the caps down. i gave the oil pump a really good go with the drill until the amount of oil in the cam area wasn't increasing but steadily flowing back down into the block.
i gave the crank another turn (with the cam locked of course) and it was much easier this time and no scary sounds. i then made sure all belts were clear and gave it a go with the starter. *bwump bwump bwump bwump* goes the block making tons of compression.
So sighing an enormous sigh of relief my next question is ...
Could my oil pump be too small for the 1.9?
Does my drill spin it way faster than it does naturally when idling?
If i set the drill to low it will hardly bring anything up to the cam but on high it came pouring out.

Did you prime the pump before starting the motor? Did you use a lube on the mains and rods during assembly?

i did prime it but probably no where near enough. i didn't use the drill for as long. I used engine oil during assembly.

A good assembly lube is far better than oil for assembly. I generally prime until the top end has oil and have pressure on the gauge. Hope your bottom end is ok.

I would put the vacuum pump back in and spin the im shaft and see if you get any oil pressure. The im shaft spins counter clockwise of course. Even if you spin the im pulley by hand you should feel some resistance when oil pressure builds slighty and oil should push out of the oil pressure sending unit hole. If you feel no resistance the oil pump might not be turning.

When you pulled the vac pump and spun the oil pump with the drill was it immediately hard to turn or did it spin easy at first while it built up pressure?
The 1.6 vac pump does not fit in the hole in the block of the AAZ. I mean, the hole is too big in the block.

the pump actually did fit but the gear size difference was the culprit! the gear wasn't engaging on the 1.6 vac pump so it was actually being starved of oil...
when spinning with a drill it took a few seconds to build pressure
i primed it good & proper got the belt back on and started it up
after forgetting to tighten the cam cover bolts (its ok its rust protection now) i drove it around the block.
it drives funny. It's either injection timing, new rings or a combination of both OR the fact that its a 1.9 not a 1.6... but all seems well now.

Good to hear you got it running! Hopefully it is just a combination of breaking in and the new engine that makes it feel funny.

So it must have oil pumping now then? Can you swap vacuum pump tops?

yes no oil issues now. It was because i hadn't primed it properly (whoops)
I tried swapping tops
no go...
just have to drive carefully and slowly for now. won't do the break in any harm either
saw 10 pounds in 4th going a mediocre pace.
the turbo sounds louder somehow?
im not driving it as hard as i did the 1.6 obviously but it definately can grunt a little harder.
doesn't break the tires loose like the 1.6 did in 1st but that too could be a break in related thing.

Glad you got it going, but...
it is not too late to inspect a main bearing, and install a pressure gauge.

1.6 and 1.9 use a different pump drive gear dont they? like how the 1.6 and ABA gassers have a totally different setup?
