Nissan Repair: nissan almera n15 no injector pulse, nissan almera, injector pulse

Question
i haven't got an injector pulse on my sr20de engined almera. there is spark and fuel pump works fine. any ideas?

Answer
Irfon,

Let's look at what is going on.  If you crank the engine over and there is spark and the fuel pump works then you have an issue with the injector circuit.  This is a seperate circuit to the ignition trigger.  The injectors work with the use of a sensor that tells the computer to ground each injector as it is required to squirt fuel.  So, first check the injector fuse, relay and then sensor.  If these are good then the ECM is defective or you have a harness or connector that is defective.
