ok heres the deal all four of my fuel injectors have 12v power to both wires when ignition is on position and power does not cut off like it should when u crank the motor. but power stays on and fuel injectors stop running for a short time but theres stil 12v power between yellow and the signal wires. so when i go to start it up it has a hard time starting up it sputters and then it runs but so rich, like theres too much gas and flooding out the motor....why is this happening?

 

There should be voltage at the fuel injector clip whenever the key is in ON(II) or ON(III). Is spark bright white at the plugs?

 

ok there is voltage at injector clips both wires on all four injectors have 12v power.
and there is strong spark from plugs and the distributor...ok but i dont understand is that when u prime the injectors...or when you have the key on the on position which is ON(II) there should be no power after a short while.... until you crank motor over...see what i mean..some what. so when you crank it over the power supposed to come back when engine starts...when it starts up and runs then the power is supposed to be on constantly from both wires...the injector wires are not supposed to have power on when ignition is ON(II) position for a long period of time without cranking the motor...kinda hard to expalain but best i could type it out thanks

 

The injectors should have constant voltage with the key in ON(II) or ON(III). I think you may be confusing the injectors with the fuel pump. When the key is turned to ON(II), the fuel pump only gets voltage for 2 seconds to prime the pump.

 

yes correct only for two seconds thats it but it doesnt do that it has constant 12v then when i go to start it it its so much fuel spitting into my motor because of the wire have constant power then my engine runs rich as fawk....this is a confusing problem do you think it could be the ignition switch not telling the ecu ground signal to stop sending power?

 

You are not understanding. The injectors should ALWAYS have CONSTANT VOLTAGE except when the key is off. The fuel injectors are not controlled by voltage. They are controlled by pulsed grounding from the ECU.
