No check engine light?

Could be the crankshaft sensor, wiring, or the coil/ignition module. Che k to see if there is power on the black/white coil wire when the key is turned to statt. If not, you have a loose wire from the ignition. If power is there, test the crank sensor.
Your crank sensor is in the distributer. Here is a test for it:

Diagnosis and Testing

For further Diagnosis and Testing of the Engine Concentrated Control System (ECCS) refer to Chapter 4 or 5 in this guide. Additional distributor and ignition coil information can be found in Chapter 3 of this guide.
CRANK ANGLE SENSOR When the ignition is ON and the main ECCS relay is activated, 12 volts is sent to the crank angle sensor LED. When a slit uncovers the photo diode and it detects the light, a 5 volt signal is sent to the ECU. The unit is easy to test but it must be removed from the engine. Refer to to test procedure below.
  1. First test the circuit to the sensor. Unplug the sensor connector, turn the ignition ON and check for 12 volts between one of the terminals and ground. The other terminals are return signals to the ECU, do not use them for voltmeter ground.
  2. Turn the ignition OFF , remove the distributor assembly and reconnect the plug to the crank angle sensor. Peel back the insulation sufficiently to connect a voltmeter to the wires. Ground the coil high tension wire.
  3. With the voltmeter connected to a good chassis ground, turn the ignitionON and slowly rotate the distributor. One of the return signal wires should have 5 volts off and on with each degree of rotation. The other should have 5 volts off and on with each 180 degrees (4 cyl.) or 120 degrees (6 cyl.) of rotation.
  4. Visually check the rotor plate for rust or damage.

If the sensor tests good, replace the coil.

Have you checked the cam sensor or distributor?

Sounds like your starter motor is bad, but it could also be just a bad starter relay not allowing current to the starter motor. Have the relay checked first, then the starter.

Your neutral safety switch has moved a notch out of whack. You can under there and loosen it up and turn it ever so slightly till it kliks then tighten it back up, it is very sensitive and has a very small window. Check it out.

How white? I would get a can of carbcleaner and spray a little here and there around the intake area to see if you have a vacuum leak. If the smoke is real white like the clouds the you may have an internal coolant leak to a cyl.
