Try crank position sensor. Both cam and crank are reliant on each other.
"The most serious indication of CPK malfunction is intermittent start, and eventually no start"
Read more: Crank Position Sensor Symptoms | eHow.com "These sensors are often located behind the harmonic balancer and can easily become contaminated from hot engine oil or coolant."
"The symptoms of a faulty crankshaft position sensor include no start, intermittent start, and poor engine performance. This is because this sensor effects fuel and ignition timing."

A bad fuel pump should not cause a lack of spark.
Smith: did you check all the power and ground connections related to the ignition and alternator? Did you check the spark plugs, wires and coil pack?
If all of that is good it may well be the ECU.
