The temp sensor could be the problem, try replacing it at the back of the engine inbetween the two cylinder heads, there is a housing with a few sensors on it, replace the one with the green connector and two wires on it.

SOURCE: My 94 Toyota 4 Runner does not start.

Make sure you have the timing right. Best way is to take #1 spark plug out, stick your finger in the spark plug hole, and turn th engine until it starts to blow your finger out. Now you're sure it's on compression stroke. Then, trun the engine by hand to get the timing mark set to zero. Now, take your distributor cap off, and make sure the rotor is pointing to #1 spark on your distributor cap. Where ever the rotor is pointing, is #1. Check rotor direction of rotation before you put the rest of the wires on.
You still may have to turn the distributor a bit once you have it close. When you start turning it over, turn the distributor slowly one direction and then the other until it starts.
If you have all that done right, check for spark, and fuel, and get back to me.

Check HALL sensor , it's probably inside the distributor , another name for it is a camshaft position sensor.

My toyota 4-runner sat for 3 yrs and now it turns over and wants to start but won't what may be the problem

If it sat for 3 yrs without starting then chances are it is the fuel. I belive most of the older toyotas had a drain on the gas tank, I would reccomend draining the gas and replacing the fuel filter to start with, just keep in mind that if it has an electric fuel pump there is a good possibility that it has gone bad from sitting. P.S. if there is no drain and you can't get the fuel pump to work and pump out all the old gas then I would suggest getting a universal fuel pump to remove all the old gas, or you can try to syphon the gas out and is a pain. Hope this helps you out, if you have any more questions then add a comment and I will get back to you.

Does truck have to be running on my 1990 toyota 4-runner 4x4 ?

No, you can do it without the engine running. The power assist just makes braking easier. Just make sure you don't move the pedal till the bleeder is tight, then pump it back up an do it again. Start at the right rear and move towards the front left. Hope this helps.
