sr20det fuel pressure idle problem

[Anthony187]

Ok here wee go I got this big as problem with my sr I have tried too fire up but would die, have too keep rpms up so it won't die but even at that still acts like it wants too die , I tried adjusting tomei fpr and wont adjust stays at 70 I have 810cc injectors z32 maf and 264 cams. Maf is wired correct ly cause it revs all the way too my 2step. While its running the fuel pressure gauge just drops all the sudden too 0 out of nowhere and car turns off that's at idle. I have a brand new walbro 255 pump. To me it sounds like a vacuum leak or a fuel problem maybe too much pressure thats why it runs better at high rpm. Anyone had this problem, any questions please post and I will answer anything really need the help
