2 of the rear cylinders (#3 and #5?) of my 90 maxima are not working now. The wires and plugs are good. Compression test says the pressure is fine. So what could be the problem? Fuel injector? is it hard to get the injectors out and test?
thanks.

 

how do you figure something like that out?

 

1 3 5 injectors are prone to go out first. Take off the injector plugs and do a resistance test. It should be ~10-12 ohms. You can also see if your injectors are working by putting a screwdriver next to each injector and with your ear to the handle listen for a strong tick sound. If there's no ticking or weak ticking then the injector has a problem. Sometimes it's just the electric contacts being corroded and need to be cleaned.

 

check your wires leading to the injectors.. my harness has a problem and it misses in one of the cylenders sometimes..
