My blazer is flooding out how to fix - 2000 Chevrolet Blazer

it sounds like you may have a pressure problem , not a flooding issue , this is a fuel injected motor and is probably losing fuel pressure , this could be at the gas tank , fill cap , fuel filter, to the injector rail , many places to check , I would have this checked by a pro as this is a fuel issue "BOOM"

Have you checked Google I found this hopefully it's not your timing or it may be flooded but doubtful have you tried spraying starting fluid into the intake while cranking it

You have a bad injector or a defective throttle control switch. You can test the throttle switch if you have a ohm meter, if you do get back to me and I will tell you how to test it.

S-10 blazer with 4.3? If so, its the "spyder" injector. One of the injectors is stuck open and fuel is pouring into the engine as soon as you turn the key on. Very common problem. Be sure to change oil after you replace the injector unit, a lot of that gas will be in the oil.

injectors are stay in open loop, this means that they continue to pump gas constantly. does check engine light come on?

Yes, if the key is on, and there is enough power to turn on the fuel pump, you can flood the car.

replace your injectors

Sounds like you need to take it in for a computer diagnostic. Check your fuel pressure and fuel volume.

distributor may be wet and when that happens it will not send fuel to the engine because it will flood

its a sensor
