I'm at a little bit of a crossroads here...
2005 Excursion with 230K miles on the clock. New batteries, good charging system and ALWAYS see 47.5V to 48.5V FICM
power on the SCT live wire.
When it is cold, usually a longer crank than normal and runs rough, until driven about three miles. Also see hard start on warm starts. Feel some surging at light throttle application. Hot starts are OK.
I did the injector test on IDS and when it was ice cold, I will only hear two injectors fire. Another time I did the test ice cold, I heard 6 fire. If the test is repeated when hot, all 8 fire.
The question is, can I have six bad injectors, or could the FICM
be responsible, even though FICM
power is rock solid around 48V?
