    That sounds like it could be a problem with the ignition module inside of the distributor, what year is the vehicle?

If you have an external fuel leak its gona need to be fixed. If its a injector thats stuck wide open it needs to be replaced. All I can say for now untill you can be a little more clear on whats going on. It would seem if you can see fuel leaking you would be able to pinpoint what the problem is and repair it.If you turn the key on without starting it do you see fuel leaking or is your problem its running so rich it doesnt run right.

I suggtes removed the electrical connection to injectors also coil to see if it still pumped fuel or over pumped fuel into throttle body. Also check gaskets.

Idling problem

need to adjust idle speed by turning air adjusting screw on throttle body idle should be 750 - 790 RPM. make sure spark plugs and wires okay. make sure distributor cap and rotor good.replace fuel filter do a little tune because if engine not fine tuned one bad cylinder will cause engine not to idle if you have fuel injection system clean fuel injectors by filling gas tank full add a can of seafoam to fuel tank see what happens.

90 Civic DX. Cranks but doesn't run. When towed in gear it will run, but 'bogs out' as soon as throttle applied. Engine floods upon trying to startup. Plenty of spark, fuel and air. Though

First I am not aware of two flaps or throttle plates in the body, but I do see a rubber diaphram with a rod that could open a plate with vac.
If you have something blocking air entering the throttle body it could cause the engine to flood. A faulty temp sensor could also be telling the computer to dump extra fuel into the cylinders, but you should have a trouble code for that.
If the plugs are getting spark the ignition system is working.
What would happen if you disabled the fuel pump and started it without extra fuel ? You could have a leaking fuel pressure regulator or something allowing extra fuel into the cylinders.

Cranks but wont start

you need to check for spark at the plugs while cranking.then check for fuel entering the intake at the don`t say if its a 4 or 6 cylinder.if its a 4 cylinder you can look into the throttle body while someone cranks the motor and you should see fuel squirting into the intake.if you have no spark then check to make sure the cap and rotor is in good condition and the rotor is turning(if not then the timing belt maybe broken and needs replacing.also check the plugs as if they are worn so bad you won`t get any spark.a common problem on these is the coil pickup in the distributor going bad.there is a 2 wire connector that comes out of the distributor with a plug,if you follow this wire back into the distributor you will see the pickup.also check and see if you can hear the fuel pump running while cranking,you may have a bad fuel may have to remove the gas cap and listen at the filler neck or listen under the car were the gas tank is.if the fuel pump is not running then you can hit the fuel tank in the middle while someone cranks the motor and it might start.if so then the fuel pump is no good another common problem.there is a fuel pump relay under the hood on the drivers side that sometimes goes bad or there is bad connections.most of this checking is good for the 6 cylinder as well except you can see the fuel squirting into the could also be a bad computer that will have to be checked out at a shop.

I think you may be on the right track with the fuel pump idea. Check your fuel pressure - it could be the pump or just the fiter screen in the tank. You don.t say what kind or year of truck you have - I am guessing the pump is in the tank. (Although you do mention a throttle body / fuel injector)
