New Holland LS170 Error F04 but running fine

[gwbarr]

I've got an New Holland LS170 that was running fine and then threw an F04 code (fuel solenoid) but did not shut off. It continued to run just fine. I parked it and restarted and got the F04 code again but, once again, it runs fine (just has a blank display with only the F04 code showing). Knowing the problem was NOT the fuel solenoid (since it runs) I went ahead and replaced it anyway but, of course, it didn't help. I went through diag mode and everything seems to be OK. Also cleared all the existing codes. When I turn the key on I got an immediate F04 code again. Note that I did leave the battery disconnected overnight as well with no change.
Anybody have any idea what is going on???? I'm starting to get afraid I have a control board failure. Since they don't make them anymore that is very problematic.
thanks, Glen

Just an update for those watching. The wire from the control board to the solenoid was fine. Turns out this was a continuing problem from me being stupid in the past. I drilled the control board mounting panel for a level and hit the control board (didn't think it went all the way to edge). Like I said, I was stupid. Anyway, I had to solder a replacement resistor around one of the surface mount ones and that solder had failed. Soldered it back and all is good again.
