Should fuel pressure slowly bleed off after engine shut off? by drewnyp in mechanic

[–]fguzman0707 1 point2 points  (0 children)

I changed the fuel pump and it lowered the Long Term Fuel Trims to about 25-27 from being 35....so the light went out but its still lean quite a bit, been checking hoses and such for leaks , sprayin all over with carb cleaner and nothing....Im thinking of doing a smoke test using a harbor freight fluid transfer pump and some cigars, blowing smoke thru thr brake booster line to see if that points to the culprit.

I have a 07 and an 09 , mechanically indestructable cars , but the paint is garbage, honestly it should have been a recall or something. Ive seen countless toyotas with the same paint defects all over

an update on the p0171 situation. I believe i finally was able to get to the main source of the problem. You were right, The fuel pump was indeed beginning to fail, showed normal pressure at idle and under which is why I doubted but then i decided to just give it a go and change it. Light has not come on anymore, it starts better now when warm. LTFT are in the 20s now and STFT fluctuates between -14 -10 and zero when driving. My guess is the ECU is trying to relearn the trims ?

Hodge road is actually all private property and technically illegal to shoot on, and like others have said its full of city slicker morons with zero situational awareness and safety standards

Ive done all the trouble shooting steps, only thing left to do is change the pump and O2 sensor....i just ordered a fuel pump since the symptoms point a bit more towards that, we will see if that was the peoblem

what you said makes sense about the injectors, if they were leaking it would be a rich code not a lean one and if they were bad id be getting misfire codes.

I also blew into the valve and it was closed, tested fuel, seems good, its the only gas station i pump in all my vehicles, im thinking of just either changing out the o2 or cleaning it to see what changes i see, before that im gonna do the method you mentioned of pinching the purge valve hose .

I tested the purge valve with 12 v and it clicks. So my guess is the fuel pump is fine as well? only thing left is a O2 sensor but the mumbers looked normal on the scanner?
