Hi, I have a 1987 Nissan Sentra Wagon and the engine wont start. It happened after a rainy day when i tryed to start the engine it would turn over but not start. I cheked the ignition coil wire that goes to the rotor and the spark there was weak only shot about every 2 - 3 seconds. I changed the ignition coil (that didn't work), i changed the ignition module/control (that didn't work) and lastly i changed the ECU and it still wouldn't start. I tryed and tryed for about 2 weeks and I'm almost giving up the whole thing. Any suggestions as to what to check for that might be causing the problem?

This is my car:

Inspect and test the power transistor and the crank angle sensor.
