I think you have hit the jackpot here with your issues! The p1272 and p1274 point toward and electical issue with you #2 and #4 injectors. This could be IDM or wiring (engine harness, UVC, VC plugs or injector soleniod). I would bet its not IDM so that leaves you with wiring or soleniod (electro magnet). If that scanner is still availible run a buzz test. you probably will not hear the 2nd and 4th buzz. First it will buzz all eight injectors then it will go in order 1-8 as 2 and 4 come up you won't hear them is my guess.
The P0263 is also a concern as it points toward a #1 issue where it failed the contribution test.
to see the description of the codes check here down the page a ways (not quite to the middle)

i did the buzz test that is where i got thoes codes i have looked at all the wiring before i had it scanned so that would led me to belive that the soleniods on #2 and#4 are no good but would this be the reason for the no start when hot

Well there aren't any real IPR codes. They manifest themselve in ICP codes. If there is a oil pressure issue it could be cause by the IPR but show up as ICP codes.
I always have to look up the cylinder numbering as I can't every remember it off the top of my head.

update
well it is better than it was i put in valve cover gaskets and the uvch and that fixed some of the problems now let me ask a ? if the rear pass side oil galley plug is leaking would this cause the 1211 code i have done the hpx so i was thinking this may be a problem i have a new plug but as i look at it it looks like you have to take out the down pipe is this the case
