So as the title states ive changed out the stc fitting. That fixed it for a few weeks. That didnt fix it. I then did the stand pipes and dummy plugs and the still didnt fix it. Ive tried the unlplugging of the icp sensor and thay sdoesnt work either. Im lost and confused. It starts perfectly when its cold but not when its hot. I dont kniw where else to turn.

 

You should do an air test on it to find the leak, also pull the IPR valve and check the screen on it. You might have a bad Oring on the top of an injector, that will cause a hot no start as well. You can't get that oring from the dealer but you can find them as a kit on Ebay for about $9 an injector, it will have all the orings. they are also made by the original manufacturer. The dealer will tell you the whole injector has to be replaced if that top Oring fails, not true though
