Whats the problem in the first place. without a problem we cant help you out.

What is the car doing? from what you told us sounds like something to maybe do with the injector. Let us know so we may help you. Lot of smart people around here.

no fire on cyl 3 and 5
-has spark
-changed injectors/fuel rail/pressure reg/filter
-new coil(s)/ignition modual
-new iac/tps/map/crank sensor/coolant sensor
-changed ecu
if u can think of it , i prolly changed it.

i think it has to do with the wiring going to the 3 and 5 injector but i dont know what the specs are supposed to be to check... any help would be awsome, this problem doesnt seem to have a fix :(

do a injector balence test on them. that will either confirm or rule out injectors. Buy or Borrow a balence tester and a fuel pressure guage. Pressurize the line and check all the cylinders, record your readings, and replace them if they are off by a lot. If you need more info on balence testing injectors, let me know. Good luck.

i already replaced the injectors

hmmmmm, well, sounds like maybe a problem with the wiring then. Try following it to see if you can find anywhere where it got hot and melted or anything.

check the fuse in the underhood Elect. center, and maybe check for any codes you might have then reset the ecm by removing the fuse for at least 30 sec.then see what you've got Good Luck!!

did you check to see if the rocker arms arm moving
maybe a lifter has collasped
some one else had this happen in one of the posts i read

and if you have a noid light
plug it in to those conneectors to see if u have a pulse
autozone will prolly have it around $7.00
if you have a pulse should be ok
i don't for sure about having 12 volts to both sides
