I would first try putting a small amount of starter fluid in the air cleaner when it refuses to start. If it starts then, it is likely low fuel pump pressure which can be caused by a clogged fuel filter, bad fuel pump, or a poor wiring connection to the pump.

SOURCE: 1992 Toyota Previa van,Oil dripping onto exhaust manifold, replace head gasket? need a free manual!
The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.

You need to check a couple of things. If your car has been sitting, then it could be any of a number of problems. Check to make sure that you have the three things your car needs to run. 1. Air- is the air filter clean with no blockages like mouse nests on the intake side and also in the exhaust pipe!! 2. Fuel- Do you hear the fuel pump kick on for 2 seconds when you first turn the ignition to the run positon? If not, your fuel pump could be suspect. 3. Spark- If you have air and fuel, but no spark, then your ignition system is under investigation. Be methodical you need all 3 of these things for the car to run, without any one them your stuck!
Hope this helps you out!! Try running the car on propane, if it runs beautifully, then you know it's a fuel delivery problem.
SOURCE: 91 Toyota Previa AWD - Swap original engine for Previa Supercharged engine
I do a lot of work on Toyota Previa before; including rebuilt engine, swapping engine and transmission and lot of things in between, but never swap a normal aspirated engine to a supercharged engine or diesel. Since i have some experience in Previa, I would like to share my opinion with you regarding your plan to swapping the normal aspirated Previa engine to a Supercharged engine. When you do a swapp like that, you will not only be dealing with just swapping engine, but some wiring, computer, throttle body, air cleaner assembly, extra frame and pulley on the accessory items, transmission as well as a right rear end to get the correct gear ratio to accomodate the new engine and transmission. I can go on even more, but let me tell you this, beside less headache, it would definitely cheaper if you were to find a Supercharged Previa and fix it up. However, if you are totally motivated to do this project, keep in mind, this engine swap will be a long term and time consuming project.l I wish you best of luck and have fun!
