Alright my injectors arent spraying, they do one lil shot at first, then nothing. Swapped fpr's, rails,resistor boxes, tried 3 different chips in the ecu, ecu is throwing no codes at all, fuel pump is priming each time the key is turned.

Im running 450s with TE, well not running, watching them not do ****.

Any idea?

thanks

First thing i'd like to see is if your pump is pushing what it is supposed to. Is fuel reaching the injector. Disconnect fuel line and crank the key. Is fuel coming out in a steady stream?

Now if you get a stream, then that would rule out any electrical problems associated with fuel delivery

fs

 

getting lots of fuel, ive narrowed this down to ecu, or possibly grounds, could the grounds even have anything to do with getting spark and everything, and just not making the injectors fire?

 

have you fixed the prob yet? i'm experiencing the same thing...had to post it up even though this thread is ancient cus the PM's weren't working

 

up again

yes the grounds are very important. it can mean running and not running motor. check to see if you are getting any voltage to the injectors. the injectors you are using makes a big difference.

if you have a resistor box and use a injector that does not need resistor box, you don't get enough juice to open the injectors. If you don't have resistor box and use injectors that require them you may damage the ecu.

hope this helps

good luck

 

oh, also, do you know if you have spark? I believe if you don't have spark, the injectors will not fire

 

I'm getting fuel pressure, the gauge on the fuel filter tells me so. I am getting spark. I have the standard DSM 450cc with resistor box. Checked all grounds, everything is cool. Still waiting to check voltage of injectors. I know they are getting power, just haven't tested how much. How many volts should they read? I was going to test my bro's AWD talon because they have the same setup w/ a resistor box
