They're being "funny", ignore them. Apart from possibly jj who's probably just being clueless.
Your ecu is telling you what's wrong mate, take note. If it hasn't told you it's got fuel pressure problems then you won't have fuel pressure problems, at least not ones that the ecu will stop the engine over. Check out the injector loom, it'll most likely be a ropey plug connection or a wire that's rubbed through and is shorting to earth somewhere.
Edit: what's the code number that came up? Cheap generic readers can misinterpret the codes, worth checking it's actually pointing you in the right direction.
