Fuel pressure problem

[J Speak]

Here's what I have Ta49, 009, alky, Turbotweak chip, walbro 340 hotwired.

First, My car will not build fuel pressure until it running.

Second, Once the car is turned off it imediately starts dropping fuel pressue. 40 to 0 in 15 seconds.

Third, At wot at 26 lbs of boost, with o2 @ 800 I get 3 degrees of knock.

Forth, I can sometimes smell fuel after I get into it.


Thanks for all of the great info.

Go to www.gnttype.org or do a search here and run through the basic fuel system trouble shooting guide. If the guide points to injectors not closing I wouldn't rule out a leaking fuel line/fitting because of the gas smell.

One of my orings for the fuel injectors is ripped and the oring for the fuel line to the bottom of the regulator is shot. Does anyone know where I can find these. Thanks Justin

Probably autozone, pepboys, dealership, ect. Or there's always the junkyard.

make sure you put a dab of motor oil on the o rings before you install them.
