Try holding the key in the crcnk position while you slowly move the shift lever from park to nuetral and back to park. If at any point the vehicle tries to start while you are doing this than its the nuetral safety switch. From your description it sounds like the nuetral safety is the problem.

the only way i found that you can replace the ignition switch is to take it to somebody who has a strong enough drill bit, they will then have to drill out the rods that appear to be welded in, the guys at the dealership ended up really struggling and i got stuck with a big bill,
by the way any auto parts store charge you about $100 for the ignition switch as well as $100 for the lock cylinder which chances are you will need at that point, especially if you have the problem any of the older toyotas have, which is keys broke off in the ignition,
for as great of vehicles as toyota has made you would thinnk the keys would be stronger, but my previa van is the third i have owned and is the third that had a key that broke in it, and this one eventually stopped turning with only have a key, and $300 later and after every homie of mine who was a mechanic telling me they were lost on this ignition, and it is running again, so best of luck to any who check this out mcl
Why use a drill bit? A 4.5 mm metal drill did the job for me in approx. 2 minutes. (A 91 model though).

I had a similar problem, hitting it may work some times but I think the contacts in the solenoid are worn out, replace the contacts, I managed to buy them at the local Auto shop, but not easy to find, or replace the starter.
Removing and replacing the starter is not so easy.
Hope this helps.

try to change the trans oil and filter possibly need to change, looks like a transmission shift solenoid is the problem or trans computer the oil and temperature will get it last longer also but would likely recommend to have it diagnose by a transmission specialist to fine what causing it

the cheap and best to do is to call a locksmith to fix it.

try flushing the cooling system. the heater core is probably crudded up. this may help.

Go through the steps, pull the air filter out and shake out the mouse nests, pull the spark plugs out and pump in some fresh fuel, make sure you are getting spark before messing with the fuel, Then give a go, If no spark, you will need to check the coils, the wires, the plugs, the computer, also has an ignitor somewhere I think. If it won't pump gas, check the oil, You should have found something by now. Hope this helps.

It almost sounds like there is to much refrigerant in the car and your high pressure switch keeps cutting in and out.Let a bit out and see if it gets any better. Good Luck

In the right back of engine compartment--just in front of the driver.

I assume you mean a 1991 Previa (that was the first year of the model). It is likely you have broken a small spring inside the door that connects the handle to the latch. The only way to tell is to remove the inner door panel (two screws: one under the door handle and one midway along the upper part of the interior door structure then pull out and up).

There is a small hole in the clear dashboard cover by the odometer. Find a thin pen or pencil and press the small tab located beneath the hole and that will reset the oil change sensor.

Does the handle have tension when you lift it , or is it free floating? Could be a broken plastic lever on the inside of the handle. Does the electric unlock work for the other doors? Can the door be opened?

You could call a locksmith who will reach in by the window glass and release the lock. $50 to !00. Less if you drive it to his shop. That will get you in, but it may happen again. I don't see much choice but to remove the door panel and take a look. Remove all visible screws, some can be hidden behind plastic plates. The rest of the attachments are probably plastic snaps and clips. Remove the panel and see what is not happening.

Auto parts stores, online, or perhaps the library may have a Chilton's manual. it will have full pictures and details. Well worth the $10. I've done numerous similar repairs to my wife's Sienna. Lock motors, door handles, blown speakers, power window motors, etc. All parts are available on line.

If you look at the motor you will see some wires running down to the side of the motor or on the top side of the motor. There should be six or eight (six or eight cylinder, one wire for each cylinder), these are the sparkplug wires going to the sparkplug. There is a black rubber boot covering the spark plugs so you can't see the plugs but if you pull the cover back with your finger you can see the spark plugs. Don't do this when the motor is hot or running. The black rubber boot keeps water and dirt off the spark plug.

gearbox filler port is usually on the side of the trans about half way up. It only gets filled up to that point. The fitting looks like a plug and takes a 3/8 or 1/2 inch ratchet to open.
