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

I have a 2001 Chevy Blazer with 4.3 liter have to keep putting gas in throttle body for it to start.What might be the problem?

if your car starts after putting gas in throttle, means that you have no sufficient fuel feeding and one cause is the injection system not providing the need fuel, pressure regulator the second cause,or the fuel filter is blogged.

2001 blazer wont start ran fine before turning off has fuel pressure has fire check timming ok relaced coil ,ing moduel crank sensor dist cap could it be the anti theft ?

You say it has fuel pressure, if it has sequential fuel injection it needs about 70psi to start the engine.
If it cranks and has spark to the plugs, the anti-theft system is not involved.
You did not mention the rotor, I assume you have spark to the plugs not just out of the coil.
If you have not yet checked cranking fuel pressure, I would start there. The pump could be weak or the filter stopped up.

On a 2001 chevy s1o blazer,4.3 engine, what is the secondary air injection system, what does it do, and where is it located

it injects air into the exhaust to reduce emissions, burn off carbon monoxide and hydrocarbons. it is a system of tubes and pump, best bet is diagrams, which i cant post here, so suggest chilton or hayes repair manual $30 at auto stores with trouble shooting, diagrams, and directions.

2001 chevy blazer won't start, no fuel, replaced the filter, won't start, when primed runs until out of gas, I hear the fuel pump working, but no fuel, could the pump be bad and not enough...

Hi Ralph,
First let me say that Jeremy W's answer is absolutely correct.

However, I would like to take a moment to applaud you for your question. Most people would not bother to ask what the correct fuel pressure should be. YES! it is absolutely possible that the fuel pump motor could be spinning and not pumping fuel. This is WHY the fuel pressure should be checked, because this is the only true test that will tell you if your fuel pump is working correctly.

Then I would also like to add that if you find that the fuel pressure is correct, then this only eliminates your FUEL DELIVERY system. It does NOT eliminate your FUEL INJECTION system. It sounds pretty obvious that if it runs when you add fuel to the intake that the problem is definitely fuel-related though.

So if you find the fuel pressure to be OK, let us know and we can help you diagnose the fuel injection system.

You are going about this the right way---isolate the SYSTEM at fault first. Only then can you run pinpoint tests to determine the actual cause of the problem.

Drive on!
