Pintara Error Codes And Hard Starting

[ronniebe1]

I have a 1986 Pintara auto sedan, the problem I have is that at times it will not start I have fuel/spark etc, other times it will start ok, though have noticed a bit rough on idle, checked error codes and it came up with 22-fuel pump / 23-idle switch / 31-load signal / 32-start signal, well to me this is all greek, is someone able to tell me what and if the above would cause hard to start at times and how to replace and install new items, if more info is required please contact me.

That's a fair few codes. At a guess, bar the fuel pump one they look TPS related (idle switch, load etc)
