Having a problem with fuel injectors on 1993 Escort GT,2 of the injectors are working fine , the ones on the # 1 and 3 cylinders. But the ones on #
2 and 4 are doing nothing.Have swap them with the good ones and with others I have , makes no difference.Checked voltage seems to be fine, but its a constant voltage, Dont know if it should be cycling to make injectors pulse. Any help would be appreciated. Thank you
