Unplug the suspect injector and use a "noid" light to check for injector pulse, if you have pluse then replace the injector.

"what can it be the problem? " - either it's not getting the pulse to open or the coil is bad. Third possibility is a clogged nozzle. -- You can check the coil with a ohm meter if you don't have a noid light handy. A good coil should be around 12 ohms resistance.

But tenspeed that still won't tell him if he has a pulse for the injector, only the ohms for the injectors coil assembly.

Fantasma - the coil is in the fuel injector. When the voltage is applied, the valve open and fuel sprays out. //// Tennisshoes - If he has a good coil, you can assume the pulse is not there. More people have meters than noid lights.

my injector was out due to a bad wire harness, years ago.
