97 blazer

Have the fuel injector pressure regulator checked. Also, make sure the correc fuel pump was installed... I believe the fuel pump for that vehicle is located in the gas tank itself.

To much pressure on gas tank when i take cap off, alot of pressure help me on my 2007 chevy tahoe

There is pressure and yes it can be allot. Unless the check engine light is on there is not problem. My Corvette really gets pressurized when i remove the cap, esp on hot days, have had 2 of them both did the same think. the system can build up to about 7 PSI and that is a real pop when you pull the gas cap.

2004 chevy suburban fizzing sound from gas tank

Perhaps the carbon filter solenoid is stuck closed and pressure is building in the tank. The fizzing could be vapor leaking around the gas cap. If there is no error code for the carbon canister, try and buy a new gas cap. A bad gas cap will throw error codes.

When i fuel up 88 blazer, there is pressure building in the gas tank, ( it hisses when i open the cap) and when driving down the road it seems to be very sluggish and sometimes even dies... but this seems...

the pressure in the fuel tanks supposed to be there,your fuel pump,,,pumps 180lbs of pressure to the engine all the time.your engine requires it. so if you do not hear that pressure when you remove the gas cap,you do have a problem. but it does sound like you have a possible fuel injector or maybe 2 fuel injectors clogging.simple to give you solution.add lucas fuel injector cleaner to your fuel tank.a clogged fuel injector will seem like an engine misfire also,just because fuel bulds in the cylinder at times,then the spark plug fires and then BOOM the engine misses while in motion. sound familiar? the lucas costs $5.00 and will treat 25 gallons of fuel. try this,and please let me know if this helps!!
