I have a 2001 honda civic that crank no start...i checked the spark and injector pulse but i dont see any on all plugs...i recently replaced the crank sensor and still no start...i noticed the green key in the dash is not turning on at all...its supposed to be go on and off after...so i bought a immobilizer unit online and installed it.now the green key light kept flashing..try to start the car but still crank no start...is anyone has the same issue as what im having right now....if you replaced the immobilizer unit,do it need to be reprogram??? Is it the immobilizer keeping my car not to run? Please i need help on this one...thanks a lot...

Any time the key, immobilizer unit, or ecu are replaced the car has to be programmed. The immobilizer and ecu have to be programmed to each other and the key programmed into the ecu.
