91 buick regal. fuel coming out of throttle body when turning over the motor

Throttle body or carburetor ?

Pull the air cleaner off and crank the engine. If puffs of air come come out of the throttle body when cranking the engine then the timing is not set correctly. Otherwise, after cranking pull a spark plug and see if it is wet with fuel and if so this indicates an ignition problem (coil, distributor/cap/rotor or faulty ECU).

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/dave_fb2c45146b845cea

First, lets be clear with terms. To crank is to turn the engine over, you can do this manually with a wrench on many vehicles. It requires no spark or air. To turn over or to fire is when you achieve combustion. Example: You could pull the spark plugs on a vehicle and turn the key and it would crank, but it wouldn't fire or turn over.

Now it sounds to me like your vehicle is cranking but not firing unless you pour gas in it. My first thoughts are fuel system. I'm assuming it can't be fuel pump because it runs once it fires. Perhaps the fuel pump isn't priming itself, or perhaps somehow air is getting in the line between the injector and fuel pump? Test the fuel pump first by turning the car from off to on (not starting, just on). You will usually hear a short buzzing noise coming from the engine bay that stops shortly afterwards, that's your fuel pump pressurizing the line. (Pro Tip: If you ever try to take your key from off to straight to start and the vehicle doesn't start on the first try, but does the second time no problem, try delaying at on for a moment before trying to start. This gives your fuel pump time to pressurize the line.) Assuming your fuel pump is charging the line, the next place to look would be at the path the fuel takes to the throttle body. When you crank it over and it doesn't start, are you getting any fuel? If you can't see where the fuel enters the system try smelling the exhaust while cranking without it firing, if it smells of fuel you're good and need to look at air flow and spark, if not it's a fuel issue.

Past that, I'll leave it to someone more experienced than myself, but that would be how I troubleshot my own vehicle.

Could be a dirty throttle body or a faulty idle air control valve.
The computer controls idle speed by regulating the amount of air entering the intake thru the throttle body.

when you turn the key to the start positoin do you hear the fuel. and do you know if you got any spark?https://www.facebook.com/TedsRepairs link to my garage

maybe this can hekp.

Dear,

You have to pump the fuel pump and bleed some fuel from the injectors so to bleed the air as well.

due to air blockage in the line its not letting to crank the engine.

please look for it

thanx

check your fuel filter first! wouldn't be a bad idea to add fuel injector cleaner next time too

replace the ignition module,under the coil pack.

i am assuming that this vehicle will not start without the gas poured into the throttle body? If so then there is a fuel dilevery problem which can be coming from injectors that are not firing due to clogged injectors or a malfunctioning injection pulse. or clogged fuel delivery system which is most probaly not the case due to you changing the fuel filter, or a bad fuel pump. you have some testing ahead of you.
