Ill start out by telling you guys everything i've done up to this point. I've popped all the injectors an number 2 seem to act alittle different when i popped it. so i swapped #1 injector an #2 injector an nothing changed, it stayed on #2 I also swapped the dv's around an nothing changed. Then i done a compression test an all cylinders were 370-380 so that rules out the motor. Ive also checked the valve lash an it was all fine.

Could it be a air leak or something cause the fuel at the injection pump is milky looking (i have a air dog) or should i just go ahead an buy a new injection pump?
