I just finshed up my head gasket change on My 03 Hemi both heads.
When i went to do the first start up i immediately got P0357.
I know what the code means but cant find anything to lead me to where the problem could be.

I have done a search on here with no results as for the internet also.

Any help would be greatly appreciated.

 

time to check each of the coils for proper function (see the AHHHHH P0300 thread for video on how to do this)

Then check the grounds... My bet is you forgot to plug in one of the coils all the way when you put them back in.

 

Thanks, I will start there.

 

So i was looking back over everything today and found i did indeed have the #7 plug wire barley hanging out. Plugged it in snug and and went to start my truck after putting the Neg cable back on the battery. turned the key let it sit till all the lights went off then started it. Still making a noise but thats something along the lines of a lifter(ill get to it tomorrow), but the CEL light is still on with P0357

 

go through and unplug and plug each coil back in, if you still have it then physically check the coil for proper function.... also make sure they made a "click" sound when you put the wire back on the plug.

 

Thats what i did when i found #7 lose.
I guess its time to try each coil.
I wish i had a spark plug wire diagram that was easier to read
