Low fuel pressure
went to get car mapped hatch sti whilst driving in vacuum it's suppling fuel but once the boost gauge hits 0 just as hitting boost it stutters and goes lean mapper put a pressure gauge on fuel hose and this is all it gets at idlehttps://cimg8.ibsrv.net/gimg/www.sco...84682d4ce.jpeghttps://cimg9.ibsrv.net/gimg/www.sco...e661b7c1a.jpeg First reading is straight after starting engine second one 30secs later |
Fort to add it has new fuel pump and 650 injectors |
what pump was fitted, and who fitted it? its fiddly job fitting new pump in hatch - should be reading 3 bar on std regulator
|
My mechanic and would rather not day the make of pump incase its not a pump issue someone i know thinks its the seal on the pump cradle |
When my mapper pulled a fuel hose off in the bay there was no pressure at all |
id be inclined to recheck the pump fitment.
this thread has a very detailed breakdown of how fiddly it is https://forums.nasioc.com/forums/sho....php?t=2303133 |

Easy way to check if its pump or pressure relief valve is crimp the return hose after the prv, if it rises its not the pump, its the prv.
Your top mount not going to cool much, more closed off fins than open ones, |
