I just put a s300 on my EG,and after the car is warmed up it wont start, Does anyone have any idea what the problem could be?? Thank you for your help.

 

If you're too rich at idle then the FITV can help the problem when it is open. Once the car warms up and the FITV closes, it can become difficult to start.

 

I don't think its the fitv. When I run my chrome ecu it starts up just fine, but when I plug in my s300 it is just doesn't want to start. I turns over and I'm getting fuel pressure but it just doesn't want to start. I'm running 1600cc and a resistor box, does anyone have any other ideas?

 

this car doesn't have the FITV or a IACV hooked up. The IACV is, however, wired in and placed on the firewall so the ECU thinks it is there.
