No start...no spark...tried everything- I think ??? 850 1994

Thanks to another user from MVS I am now the proud owner of three ECUs with the same part numbers and version numbers.

I put in the ICU and checked it and it came up 111. I prayed and gave it a whirl and it did NOT start. I checked A6 and I got error 314 again.

I cleared the code and put in the EFI/Engine ECU and the TCU. What the heck I had all three as a set and they all played together before. All codes were also 111. I tried to start it and to NO avail. A6 still shows 314.

I am now going to try and see if there is any voltage at the ICU pins and then ohm them out to the CPS and ground. I know that this is going to be tough to do without a breakout box, but I don't know what else to try at this point...

Does anyone have any ideas of what the three overload relays do- the ones with the "J" on them??? Someone mentioned in another post that he replaced one when he had similar problems and everything worked. He did not remember which one though.

I am going to go to the junkyard tomorrow and see if I can find a OEM CPS and while I am at it I will grab the J relays.

Thanks for all of you all's help and advise. I will keep on plugging...

Don
