Toyota products usually don't use a shut-off for the fuel system.If the fuel pressure is low, you would need to check the fuel pump relay for power and then the pump.

The lic plate light are on the same fuse as the park lights so if they work the fuse is good, try removing the bulb assembly and look for things like a bad ground caused by dirt or rust, if you have a 12 volt test light you can check to see if you are getting any power to the light socket or the wires leading up to the sockets and you can trace back to where the problem is.

First things first, if you can not turn the key lock past ACC you are not doing anything with the starter. The problem with the lock must be in the lock or the linkage connected to it.The price for the starter may be fair depending on where it is coming from. You have to be able to turn the key to the start position before anything happens with the starter.

Getting this lock to turn may and may not get the trunk to open. If the lock is in the lock position right now it might work but if its in the open prosition which is where most people leave it its not going to work but because there is a definet problem with that lock its good place to start. First I would go to pepboys or some kind of autoparts place and buy some lock lubcant or deicer and spray in the lock and work the key you might luck out if it don't work its only a couple bucks if it does work you made out big time. If it don't work the unit is gona have to come apart to find out if the lock is froze or the switch. If its the lock take it to a lock smith if it the switch you will have to replace that.

diagram should be located under the hood somwhere and if not go to nearest autozone and they will print out diagram for you at no cost.

SOUND LIKE THE STARTER SOLENOID OR STARTER IS DEFECTIVE.REMOVE THEM HAVE THEM CHECKED OUT.AT ANY AUTO PARTS PLACE.REMINDER TURN OFF RADIO SO YOU WONT LOSE RADIO CODE WHEN DISCONNECTING BATTERY.

Someone will need to figure out if it is the height sensor, or the pump, or a leak somewhere.The sensor turns on the pump when the height is too low.

this car is 21 yrs old and well past its sell by date ,now is this clear rad container your refering to ? is it the over flow bottle or the radiator header tank If you do have a problem with the head gasket then it may pay you to trade it in quick and buy a nice peugeot diesel manual and reduce your carbon footprint and save a lot of money in fuel as well with 70mpg .Your dealing with a big petrol engine here in this car and lots of things could be wrong and going wrong owing to the vehicles age and their come a time when you have to give it some euthanasia and send it to the great motorway in the sky unless you have a bottomless pit of a wallet

Could be several things.If the head gasket is blown, you may have lost compression in the cylinders. You may have also damaged the spark plugs with coolant.

the starter is at the back of engine by the front of transmission on all cars.ECU chip tunning tool
