Question about 1996 Toyota Previa
It could ba a lot of things ... lets start with the least expensive:
1. Check your spark plugs. If they are dirty or worn, they will not have the correct amount of snap to get your engine going right. While you have them out to inspect them, (if they still look usable) wire-brush them to get the corrosion and carbon off the tips. Make sure the gaps are correct (an oversized Gap will keep the plug from functioning correctly). While you are in this area of the car, take a look at the distributor cap ans the spark plug wires. Do they look worn out? are they arcing when you are starting the car? If they do, you are probably best to give these parts a tune-up (at least the plugs and wires, you can leave the distributor cap until you have tried the other options). These parts are all inexpensive and relatively easy to repair, so they should be the first step.
2. Check your air filter and intake. If your engine is not getting enough air, the fuel will not light.
3. If it is not the plugs, plug wires or air, check your fuel filter. If the filter is clogged it will not be getting enough fuel to the engine, and it will take a lot more effort to start the car. Once its started, the engine itself forms a bit of a vacuum to pull fuel in, so with engines, once it's going it will tend to stay going .. but this can cause hard starts.
4. Check your fuel pump. If it is weak, it will have the same effect on the engine as a dirty fuel filter. It will also be more likely to die while you are on the road if it is already weak, so it is best to be sure that this is not the problem, to avoid getting stuck later.
Check on these issues first. If none of them solve your problem ... we can work harder to figure it out ... there are still a lot of options, but these are the least expensive and most likely to be the cause. Also, please be careful about running your starter for too long. It is not a hugely expensive part, but turning the key and running the starter motor for more than 15 seconds at a time can overheat it and eventually burn it out. I hope this helps .. if not, just leave another comment on this post and we'll move on to the next steps for you. If you want to fix the car yourself and not have to keep coming back online to check for solutions , a Haynes manual for your car could be a big help. It has a list of options that could be causing your problem, with pictures and step-by-step instruction on how to repair the issues (and is specific to the make and model of your car -- so the information is accurate and usually will give you the best fix in less time). Good luck!
