That also happened to me one time. Unfortunately my car was not
in my garage, but on the road somewhere when I wanted to start it.
I had to replace the main fuel pump (that's when I found that
the in tank pump didn't work because the new main fuel pump made the
same terrible noise).
The main pump was stuck. I repared it and I keep it as a spare
in my trunk (you never know...)

Are you sure the ignition timing is OK ? In the N9Tx engine
manual there is a description how to place the distributor gear.
It is easy to get it 180 deg. wrong. It is hard to see, but the
slot were the distributer goes in is asymmetric. You also won't notice
this with a timing light.
In that case, the engine won't fire at all (I tried that :-).
If the timing gear is +/- 30 deg. wrong, the engine will fire
but it will of course not run properly or stall.
