hi guys. i just got my car done 2 days ago, and im having some fuel problems, i think. the car has been boging down and stalling out, then it wont start unless i let it sit for a few minutes. i put a le2 heads and cam and ported intake. i put in a walbro 255lph fuel pump and ford 30lb svo's but i dident put on a adjustable fpr. also i did not connect the evap canister line that is run to the engine bay with the fuel lines to anything. hopefully its something simple that i over looked. also its definatly running alittle on the rich side. it was tuned by pcm for less. i havent had a chance to get up with them yet to ask them. any input you guys could give would be greatly appreciated.

anybody?

 

You shouldn't need an AFPR, at least not if he tuned it for stock fuel pressure. What did you do with the connection on the side of the throttle body for the EVAP lines? Are you running open headers? Do you have any exhaust leaks? Verified the coolant temp sensor it working? Scanned it? Run a data log?

 

i initially did not hook up the evap line. i was reading up on it today, and im gunna hook it back up. the coolent temp sensor for the gauge is working fine, im not sure about the the one for the pcm, ill have to check that. i still have not put it on a scanner. could that coolent temp sensor be causint the car to be running rich? should i throw a fuel pressure gauge on and see if it is at stock fuel pressure?
