can anyone tell me how much volts run to your injectors ? im doin a ls swap and it leans out when i rev it, because i pulled the plugs and the electrode arm is white, lean right ? i rev and it kinda pops revving up till it just loses power around 3k. i measured the voltage where i put all the power wires together and spliced and it read 11.7 is that good ? too little ? would that cause hte injector not to spary as much fuel ?

thanks

 

I was talking to my friend and he said its supposed to be between 10-13 ohms. You spliced the wires my friend was telling me that your supposed so test the metal prongs on the injector not the injector clip or the wires.

 

i already tested the ohm on the injectors themselves and got like 12.3 or soemthing like that, it was the same for all 4

playing around with it today i got it to rev to 5k, 4k, 3k a few times not consistently but every now and then. still need to cover the tb to get it to rev but now i can use bigger holes to get it to rev

 

Remember, the injectors get a constant +12v from the main relay and are grounded by the ecu, so they should be getting whatever battery voltage is. If it is less, measure the resistance from the injector to the main relay, and farther if you need to, to find the point of high resistance. The injectors don't need much voltage to run, as the car will crank with as low as 7v.

Also, the injectors are pulse width modulated, which means they are either on or off. There is no in between, unless it's fluttering due to VERY low voltage. Your injectors might just be clogged, so a good cleaning may help.

 

injectors shouldnt be clogged because i jsut had them cleaned but ill keep tracing back till i find battery volts. thanks
