FICM Repair

[colberjs]

After reading about this yesterday I am seriously contemplating doing it. I was hoping it would help with my cold start ad long crank time issues. I am really worried that I might do irreversibe damage to it though. Has anybody else done this and how hard would it be to really screw it up?

Haven't even checked mine yet (waiting for better weather)...when I do, and IF I have issues, then I will be having a local guy re-flow the board with his specialty tool used for this purpose...he charges $40 for lifetime garantee.

Yeah I guess checking the voltage would be a good place to start before I tear it apart.

Make sure you check the voltage while someone else cranks the engine over. If it falls below the threshold do the repair.

I did it and it cured my problems. If you are careful you won't screw the FICM up.

Do you turn the key to the on position, or do you crank the engine over?

I got that, just was confused if you were supposed to crank it and not let it start, or just turn the key to the on position.

you need to crank the engine to get proper results. check it key on engine off, key on engine cranking and it also needs to be checked when engine is at full load (wide open throttle) as well. let us know what voltage you come up with. anything below 45 volts and it needs to be done.

Nice, thanks for the replies.
