You must turn the engine over until you get top dead center (TDC) on the #1 cylinder. Make sure its on the compression stroke. (take spark plug out and put your finger over the hole, make sure air is coming out.

Then with #1 on TDC drop the distributor in with the rotor buton pointing to the spark plug wire for the #1 cylinder. that's it!

Now it should run assuming you have the other wires in the correct firing order.

here is the correct order 1-5-4-2-6-3-7-8 The distributor runs counter-clock wise. The cylinders are numbered 1234 front to back on the passenger side and 5678 front to back on the driver's side.

AnswerThe sensor is located in the distributor on the rear of the engine. The distributor has to be pulled to be able to remove the sensor.

The timing on that engine is computer controlled. It requires an engine scanner to set the timing. No other way.

Until the engine will run without the choke being pulled.

Without knowing what application you have this cannot be answered. For the majority an engine does not have to be pulled. It all about whether you can access the heads for removal or not.

no the gear stays in place , unless you take the timing gear cover off + the bolts that hold it to the cam shaft.no it won't change the position either unless you crank the engine, the gear stays in place.
