Hi, Does anyone have any suggestions.

My daughter's 1.1 car suffered a water leak last week. She had driven it with not much water in it. It was pretty hot when she got home.

I have changed the water pump as that is where the leak was. Also changed the timing belt.
Now the car won't start. The starter turns the engine, but no ignition.
I have read a lot of comments about the TDC sensor. Since the car started OK before the work, I assume the TDC sensor is OK. While removing the timing belt, I had to remove the pulley wheel that drives the alternator. Does it matter which way this goes back on? Does it have to be lined up to the TDC sensor?
I have also checked compression they are all 120 PSI except the cylinder next to the timing belt, this one is about 106 PSI. Is this variation OK.
The spark plugs are OK, and there is HT also.

Any help appreciated.

The compressions are a bit low but enough to start & run Are you sure the cam timing is OK after replacing the timing belt easy to get the cam timing 180 degrees out. But you usually get a bit of spitting & engine stops dead brieflywhen cranking. Are you getting fuel & or a spark at the plugs?
not sure about TDC sensor others may advise.
 
it will still run without the TDC sensor working correctly (As dave says there is a tiny pin that fits in a hole in the pulley), but rough as shte.

Other thing to consider is make sure you have the crankshaft in the correct orientation, when I did my cylinder head a few months back I advanced the ignition a few clicks by mistake, noticed it before I started it (wouldn't have done any damage anyhow), and corrected it, however, it wouldn't start because it was trying to exhaust out of the inlet valve, and intake thru the exhaust, causing massive flames to belch from the top of the throttle body and it backfiring. took me a good hour to figure it out! duh, now works perfectly!

First get your pulley back on right, if it sounds like its backfiring and popping, and might even get a few flames and black crp out of throttle body, then your crankshaft needs advancing or retarding 360degrees (crank to cam is 1:2 ratio).
 
Thanks for your comments.

I will double check the pulley wheel, also timing belt. When I took it off, I lined up engine to TDC and nothing was moved until after I replaced the belt.
I get a spark from each of the spark plugs and there seems to be fuel being sprayed from the jet.
It will have to wait till the weekend its too cold & dark in the evenings.
 
Thats done it, Thanks.

It was the pulley wheel on 1/3 turn wrong. That pin is so small you can hardly see it.
It started straight away.
