The pressure regulator is a diaphragm-operated relief valve with system operating pressure on one side and and atmospheric pressure on the other side. The function of the regulator is to maintain a constant pressure to the injectors at all times, by controlling the flow in the return line by means of a calibrated bypass. The pressure regulator on this unit is serviced as part of the fuel meter cover and should not be disassembled. The regulator is in your IAC valve. (Idol Air Control Valve) It is most likely stuck. Replace and watch the magic happen. Hope this helps.

Is the injector shorted to ground ?

If its blue smoke, its usually valve guides or rings in the engine.You should be adding oil from time to time.

befor you start replaceing things, if your freeon in the unit gets to low it will not allow the compressor to come on its a saftyso you cant burn the comp. up try putting freon in it first get a can that has a guare on it (around 15.00 at parts store) then see if the freon is just low. but if you know its the blower motor itts located on passenger side in side under the dash take forve box out ands you will see it

Since you replaced the coil I would guess you have no spark?

If your getting fuel and no spark the first thing I would check or replace is the ignition module. It is located in the distributor. If you getting no spark and no fuel (no injector pulse) I would replace the ignition module and the pick-up coil. The pickup coil is the round piece under the rotor in the distributor that plugs into the module. The distributor needs to be removed (mark the base where it is held in place and the position of the rotor before removing so that it can be reinstall din exactly the same position!!) and disassembled in order to replace the pick-up coil.

no need,when you hit a bump in the road the stearing geometry will alter accordingly...BUT your tyre wear will increase regardless.
