I had a no start problem on a 99 Disc 2and no ECM com so replaced ECM With a used ECM, Now vehicle will start but stalls right out and will not staying running, i have a P1672 code showing now and com with ECM now. will the P1672 cause this allowing vehicle to start and stall out and wont start again unless you cycle key? will reprograming ECM/BCM help . We dont have a Land Rover dealer here and it will cost me quite a bit to get it to a dealer but if thats what i need to do i will . Help pls =) and thanks ahead of time

 

If you don't have the replacement ECU reprogrammed, it will not communicate with the other ECU's. This is most likely your problem.
