At this time of year, the most likely cause of your problem is a flat or chilled battery. Battery temperature is critical to the electrolytic process, that your battery uses to deliver power to your vehicle's systems. Generally, a warm battery can deliver more power, than a cold one.

How do you test injectors Ford Ranger?

Haynes or Chilton book is a must before you start diagnostics. 2nd you will need an OHM meter. Depending on what ranger you have, I know the 4.0L is 11-18OHMS. a good idea would be to test ALL injectors, write down ALL OHM #'s you obtain. compare them all. And from there you will know where the problem injector is. If all injectors have no power, look at your ECM "electronic control module. I hope this helped you a lil bit
