there is a common problem with the injectors with that motor

Sounds like it's low on transmission fluid.

its possible that you need to try and turn the steering wheel left and right (IT WILL TAKE SOME EFFORT) while trying to turn the key. and you dont need to put pressure on the key , turn it same as you would when starting it normally. you dont want to break the key off.also try and put the gear shift lever up into park at the same time( thats asuming its a automatic with shift lever on the steering colum) somtimes you can get the car to close to a curb or somthing and having pressure on the tires in a less than straight position will get you locked in on the sterring wheel,shift lever and key lock possition . so with one hand pull the steering wheel left with as much pressure as you can and at same time trying to turn key with your right hand.

there is a crank position sensor that is located behind the harmonic balancer. sound like you have a bad one

Up under dash there is a fuse panel with rounder silver flasher size of a quarter

Check that as you move the shifter, that the shifting rods beneath are moving in tune with the shifter's position.If not, then your mechanism is faulty. It is almost certain that the issue lies with the external shifting mechanism.The issue may be just beneath the shifter lever, within the rubber or leather bag shroud. You might have to pull out the centre console to have a closer inspection.

the person who came up with this system should be shot, dead,, for being stupid,,,, this system sucks,,, ,

A thermostat that does not open and close would cause these very symptoms. Since it does not allow coolant to flow through the system, it will make the engine overheat. Since it won't allow the "heated" coolant to pass by your fan, the heat will continually blow cold air.
Stop driving the car immediately, becuase the next step will be some blown gaskets - especially head gasket. Other possible reasons can be as follows:-- It could be just low on coolant. if it is then add coolant... with low coolant the water pump can not move enough coolant to supply hot coolant to the heating system . also if its low the motor will over heat fast..... If the system is full then you may have other problems.. such as 1) bad thermostat 2) bad radiator cap ( not holding pressure so it will leak coolant) 3) blown head gasket . 4) bad heater core (leaking coolant out.. check the floor board under the dash on the passenger side.) 5) bad hose or clamp. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.
