Has any know why I have intermitan gas smell 05 pontanic montana


there is a known issue with the fuel pressure regulators leaking on these. You can find it on the front fuel real near where the throttle cables attach to the throttle body. You will see a small vacuum line coming out of the top. Remove the vacuum line and see if fuel comes out of the regulator. If it does replace it as soon as possible.

I found out that my 2001 blazer had no gasket in it replace them but still smelling gas and it making noise what ekse could it be I need help


If you are smelling gas it is because you are getting excess fuel somewhere
Most likely it is the fuel injection unit or the fuel pressure regulator inside the intake plenium on top of the motor there is a shrader valve on top on drivers side of air intake on the fuel lines have someone pressure test the fuel pressure when you turn the key on and off three or more times to prime the pressure then turn the key off and watch the gauge while priming pressure the pressure should be 60 psi then after priming pressure and turning key off pressure should drop to 55psi and hold that pressure for 5 minutes minimum if it does not hold that pressure and starts dropping to zero your fuel injection unit and pressure regulator are leaking and dumping excess gas into the air intake plenium and it is easier to replace the injection unit and the pressure regulator as you can buy them cheaper combined a new injection unit comes with the new fuel pressure regulator
And if they are leaking gasoline after a failed pressure test that is why you are smelling gasoline
Have it pressure tested right away as if this indeed is the cause the excess fuel could combust at one point and cause a lot more damage
A pressure tester can be purchased at advanced auto for around 35 or any reputable garage can pressure test it in front of you in 5 minutes it's easy

96 chev 1500 w/6 cyl vortex, started running rough, then smells like gas, now engine light comes on and white smoke


Either your fuel injector assembly or fuel pressure regulator has gone bad. The intake cover (upper plenum) needs to be removed to inspect both. This motor has an internal pressure regulator that is prone to leaking, should be pretty obvious (puddles of fuel under and around regulator). If you remove the cover and see no fuel then suspect fuel injector assy. It has been updated to a new design so don't be alarmed if it looks different than the old one. Good luck

Car wants to start but dies immediately. fuel pressure test bad


Couple of things, the fuel pressure held before with the old regulator but now it doesn't. Are you sure you got the tiny o-ring out when you changed it and installed it on the new one? Is there any fuel in the vacuum line to the regulator? Does the white exhaust smell like fuel or coolant burning?
