If it cranks good but won't start, and it doesn't make any horrible noises when cranking, like internal engine issues, have a helper crank it while you visually check for spark at the spark plugs. If you have spark everywhere, use a gage and check fuel pressure.
Yes, valve timing could be an issue? Do you have good cylinder compression? Use a compression gage to check. Usually if no compression, the cranking rpms can be faster than normal.

I have used the Haynes Repair Manual for the Mercury Villager to change the timing belt on my 1993 Villager, twice. I just finished last night with the latest change. I found the Haynes manual to be very useful. This is just an overview:
1. Jack up the the van and support it on jack stands. Remove the front passenger side wheel and 2 plastic splash sheilds.
2. Remove the two radiator hoses on the passenger side of the engine.
3. Remove the pulley from the water pump (4x 10mm bolts)
4. Remove the tensioner pulley, including the bracket, for the A/C compressor. (3x 12 mm bolts)
This one can be difficult because it requires a torx head to loosen the pulley and it's a very tight fit to get a torx in there. I ended up taking the torx head out of the socket then turning it with a 10mm wrench.
5. Remove all 3 drive belts.
6. Remove the crankshaft pulley. (1-1/16" bolt) You will need a good strap wrench to keep the pulley from turning or an impact to remove this bolt. You may be able to remove the pulley just by bumping it with a mallet, but you may need a gear puller.
7. Remove the timing belt cover, it has an upper and lower half and is held in place by several 8mm screws.
8. You will find that the timing belt pulleys on the both cam shafts and the crank shaft have a white paint mark on one tooth. Make sure the marks on the two cam shaft pulleys are in line with a "bump" mark on the back plate of the belt cover. The bump mark for the front cam is located at about the 2 o'clock position and the one for the rear cam is at about the 10 o'clock position. You will need a mirror and flashlight to see this one.
The crankshaft pulley mark lines up with a notch in the oil pan (I think it's the oil pan where the notch is, but you will see it at near the 6 o'clock postion.
9. My new timing belt was a DAYCO and it came with a good instruction sheet. The new belt has an arrow that should point AWAY from the engine. There are also 3 lines on the new belt that will line up with the lines on the timing belt pulleys.
10. The belt tension should be adjusted so that you get about 0.5" - 0.6" of deflection at the center between the two cam shafts.
Note: I recommend replacing both the tensioning pulley and water pump while you are in there.
A water pump is about $32 and the tensioning pulley is about $35 but it's money well spent.
I did NOT replace the tensioner pulley the last time I changed the timing belt, and that is what failed this time. I could have saved myself a lot of work if I had replaced the pulley the first time.
Hope this helps. I'd still buy the HAYNES manual.

1996 Mercury Villager... easy question I hope... where is the thermostat located... and how easy is it to replace? Thx
SOURCE: putting on timing belt .
The crank has got to be at TDC, with the marks lined up, the cams have to be lined up to their marks, then the belt will line up, If it doesn't line up, You will be walking home. If you have the old belt handy and the marks are still visible, compare them to the new belt, make sure they are the same. Pull the pin on the belt tensioner and you should be all set. Hope this helps.

I would check to see if you have spark and fuel at the motor. Double check that everything was connected back up.

there are conflicting opinions on this.
some sites are saying that the ford engine used in these is an "inteference" engine and the valves would probably have bent.
others are saying that the mercury engine was modified with a slightly lower power output, but was a "non inteference" engine meaning that there would be no contact between the valves and the pistons, and you could just replace the timing belt. all sites recommend changing the water pump at the same time as the belt.
i would recommend you ring your mercury dealership and ask them as they should be able to tell you conclusively using the chassis and engine numbers. then you can decide the best course of action.
when you have decided, feel free to ask again for more advice and instructions.
sorry i cannot give you a more definate answer
