Nissan Repair: MAXIMA WONt START, crank angle sensor, fuel pump relay

Question
I HAVE 02 NISSAN MAXIMA IT TURNS OVER BUT WON'T CRANK COULD U GIVE ME SOME IDEAS OF WHAT IT COULD BE

Answer
Hi. 2 things are needed for a gasoline motor to start and run. The first is fuel and the second is spark! First, we check for spark while we crank the motor. If there's no spark, we look at the crank angle sensor first! then primary wiring to coil packs, ignition module and all primary and secondary voltage components. If there is spark but there is no fuel delivery, we check the fuel pump and fuel pump relay as well as the electrical wiring, including the fuses and verify signal from the ECU to the fuel injectors. Other reasons that could cause the motor not to start are timing belt problem, faulty ECU, loss of compression, low battery voltage, restricted air intake system a cut fuel line, a clogged fuel filter and a major vacuum leak. I hope this helps :)
