Read post #22U0105. U could have a bad ficm or the harness is bad. Check the 3 connections. If there tight. I'd take them out and check them make sure nothong looks burned.or dirty on the connectors or the ficm side. Can u read live data on that scanner ur using? U need to ignition with key off and check ficm voltage. Then start it and see what voltage is there. Anything under 45 is no good. 48 to 50 is were u need to be at.
So, it fired up this morning and was able to cram it back in the garage!!Bismic, Hydro
I just checked plugs at the PCM, also unplugged them there and it all looks good shape and the run up to what I could chase down was solid, no ware marks.
So tomorrow I'll start getting to the FICM plug ends. I believe I'm gonna have to take this FICM off right? To check out the plug ends of the Bus?
From videos I've watched looks like it's all feel with the ficm in place so again to do a visual the ficm should be removed for this correct?
I never replaced a FICM yet is why I'm asking a stupid question
Cool, helps to know.It can be bad and show good voltage. It is a computer - it has a power board and a logic board.
I would send it to FICMrepair.com to have it checked out.
They won't sell you a new one if that one is good.
The cold snaps screw with me anymore, I have learned the hard way it stubborn way I get chest cold easily, my son screwed with me and said you need the old man scarf, dam it works lol.Glad you got it fixed -- I work out in the "big shed" at home, so I know how hard it is to play against the weather
30 miles east of Evansville? -- you are almost my neighbor, I'm about 90 miles east
Appreciate it again, hey the alternator guy learned some things as well, it was a educational event for both me and him lol.Glad you got it runnin' good!
IMO you not only fixed the issue, but you improved the reliability by doing the things you did!
