The first ones to fail have ford numbers, assuming original injectors, replace #7 with borgwarner 3 times and #8 twice. Today the number 2 ford injector has failed. Sent computer to a repair place in IL. They stated no problem found. When the trouble started I replaced #7 first time due to missfire and cel. A few days later it failed again but no cel, put noid light on # 7 and the light would cycle on and off in a timed fasion. The amount of time was consistant that the light would be on then off, so I ask the pcm repair place to replace #7 injector curciut anyway, they claim they did that. I can replace the injector in question #7 or #8 and now #2 and it will run great for a few days then an injector will fail can warranty it out and replace it and runs ok again. Voltage to power side of injectors check out ok at 12V have pinned out wire harness from pcm to injector and no shorts. I am wondering if an alternator with bad diode could burn out injectors.
