    I replaced the sensor It did not make any differance. Could it be when I replaced the crank I got it out of time? What is the timeing sequence? the gear that runs the oil pump is it timed? Does the oil pump have to be timed also?

If you aren't getting any spark, it is probably your crankshaft position sensor (CPS) that has failed.  Failure of the CPS will not allow the car to start.  It is the main sensor telling the engine where to start the timing sequence.  If it doesn't see the pulse, the computer will never spark.
If you have a spark but it just won't start, you might check the fuel pressure regulator.

No the oil pump does need to be timed. (Just the Dual OverHead
Camshafts, when replacing the crank. These must be Dead On!)

The sensor must be positioned correctly,

  1. Using a 28mm socket, rotate the harmonic balancer and pull the handle until the interrupter ring(s) fill the sensor slot(s) and edge of the interrupter window is aligned with the edge of the deflector on the pedestal.
  2. Insert adjustment tool J-36179 or equivalent into the gap between the sensor and the interrupter on each side of the interrupter ring. If the gauge will not slide past the sensor on either side of the interrupter ring, then sensor is out of adjustment or the interrupter ring is bent. This clearance should be checked at three positions around the outer interrupter ring, about 120° apart.
  3. If the sensor is found to be out of adjustment, it should be removed and inspected for potential damage.
  4. Loosen the pinch bolt on the sensor pedestal, then insert adjustment tool J-36179 or equivalent into the gap between the sensor and the interrupter on each side of the interrupter ring.
  5. Make sure that the interrupter in sandwiched between blades of the adjustment tool and both blades are properly inserted into the sensor slot.
  6. Tighten the sensor retaining pinch bolt to 30 inch lbs. (34 Nm) while keeping light pressure on the sensor against the gauge and interrupter ring. This clearance should be checked again, at three positions around the interrupter ring, about 120° apart. If the interrupter ring contacts the sensor at any point, the interrupter ring has excessive run-out and must be replaced.

Some pulley must be locked up if it does not turn over. If it turns over and no start the belt may have broken some wires going to the crank sensor.

remove your valve cover and have someone try to crank it over while you watch the camshaft to see if it turns, your timing belt may have jumped a tooth ( causes bad running and back fire ) and then broke

Sounds like a bad crank sensor or PCM. Try the crank sensor first.
