It is real easy to mix up the injector plugins if you didn't mark them? Any codes? Some swapped engines need a crank relearn procedure.

i'm not sure if yht 2 coil brackets can be interchanged side to side but that could be a possibility as to timing (wireing front to back???)

good start is check all your connections and tell us what changed from your old setup and your new setup and how your computer is tuned, did you doubble check your timing if you changed the cam????


jsut a few things to concider

Coil packs can be interchanged any way you want as long as they are plugged in right with the injector harness.

i still have the tune from the 5.3 in it..but that shouldnt effect it..i did notice a few more grounds that were not connected as i was putting stuff up tonight..i will hook those up tomorrow and try it again..

mine wouldn't start due to a ground in the wrong location. check all grounds and check them again. you have 4 of them i believe. also, don't do the same think i did and run it hard on the 5.3 tune. you will burn a piston. look in the southern section for proof.

well i know about the coil packs being the same but if you had bank 1 on the bank 2 side they may be wired differently and vicea versa

coil packs should be able to go from either side. the plug is the same on both banks.
