FICM

I'm having intermitent no start problem , when it happens the only way to start is spraying some fluid on the intake .
The voltimeter show error when I check the voltage on pin 4 with 2 differents FICM . the engine runs great with no codes.
I'm suspecting something on power supply , the logic fuse is ok and there is power. does somebody know how to test the power on the 12 way connector?
thanks for help

If your voltmeter shows error, you have something on it set wrong. Wrong probe location or out of range.

FICM ok - intermittent NO START conditions- engine never stall and runs great with no codes- yestarday it start in the morning, start all the day and fail to start at night after seating for couple hours during dinning at friends house- In the event of No start I make it run sprayin some fuel on intake so it start nice , I can drive it without any problem and if I turn off it will start normally again . I have no idea what to check -
When I gaot home last night I plugged the scanner and it show me the code P2623 but the check light was off all the time . thanks for help

Not sure if it sets off a code or not, but my 05 6.0 intermitant no start was a bad cam position sensor eventually went out totally. priced out from $30 to $130
