RB25 Idles High and doesn't like to start

[d356bud]

Well the car ran great mid winter, but now it doesn't like to start. Also it idles around 1500-1700 RPMs. I haven't changed anything since the last time I started it back in February. I didn't get a chance to reattach the wideband, but I checked the ecu and it isn't throwing any codes.

Specs:
built RB25DET
HX35
740cc injectors
rb20 ecu with a eprom chip from Carl
Stock ignition
z32 maf

Anyone have an idea?

For craps and giggles, when it is not wanting to start, try disconnecting the mass air flow and then starting it. If it starts right up immediately after unplugging it, that is your culprit. That is an easy 1 minute thing to do first. Theck check back........

u might wanna check ur fpr, when it goes bad, it will crank for a bit b/f it starts up..

Sounds like a vacuum leak to me. Some random hose might have cracked over the winter.

I'll have to give these ideas a try this weekend

Well I gave these ideas a shot. The MAF idea didn't work, it just made the car run super rich. I also check my fuel pressure and its fine. Although I did hear a strange sound coming from the gas tank. It sounded like a groaning sound from the fuel pump. So thats a problem for the near future that I'll have to address. I checked my hoses for leaks and I couldn't find any. The PVC valve might be the culprit. If it isn't then I'm think maybe the AAC or IAC?
