I installed the dsm 450's with the 10watt 10ohm resistors. I put the inline resistors on the black/yellow wire on each injector and car wouldnt crank. I reinstalled the RC 310's and the car fired right up. Could the injectors be wired up wrong?

 

What injector clips are you using? Make sure they are actually connected to the injector and make a good fit. I ended up swapping over to the DSM clips instead.

 

im using the stock clips. I modifyied the clips and the pluged up fine. I also have the dsm clips.

 

What fuel management are you using? If its not set up for the 450's then maybe its flooding?
