Hello, i am getting ready to put the new engine in my 2008 charger 3.5l sxt. I am wondering on how to prime the engine with oil before turning it on, on older engines i used to spin the engine through the distributor. Could i simply turn the engine over by hand a couple times? I also saw posts about the 5.7 hemi engines being able to crank the engine by turning the key with the gas pedal depressed to the floor, this tells the comp to not send fuel or spark to the engine, allowing the engine to crank and prime with oil before ignition. Can this same method be done with the 3.5L engine? Also how do i refresh/reset the cars computer of codes? can i pull a fuse and refresh it instead of goign to the dealership? Thanks ahead of time guys.

You can pull the ASD relay,and crank it over,and pull fuse #2 to clear PCM!

ASD should Be the front power box,No 6,might say Ignition coils/injectors
#2 in in front box for PCM

Good Luck and let us know how it goes!
So the engine turned on without a hitch, what i did was take the fuse out for the fuel pump, cranked it a few times, then put the fuse back in and it roared to life.

There is a very light white smoke that appears tro be coming from the left and right headers, most likely some oil residue, ill wait it out and see if it continues or if it burns up and stops smoking.

The second time i turned it on the check engine light was blinking so i turned it off and started the engine again and the light was solid, not blinking. The code i got was P0300 random misfire, the coils should be fine and the spark plugs are new, Im thinking it could have been the gas thats not too fresh, the car has been sitting for a bit over a month. Any tips from you guys on what i can do to make sure the engine is firing right?

even though the engine light isnt blinking anymore i still get the P0300 on the reader, does it mean its still missfiring or its just that since it happened once the computer saves it to tell you it happened?

Po300 is either a Vacuum leak,or fuel problem,pull the #2 fuse again,and see if it clears the code,if it comes back,check for what I stated here.

I think the blinking engine light means shut off the engine NOW. I'd go back to the builder for advice. Vacuum leaks are under warranty.

Your right on that, any time something in my dash blinks i turn the car off and coast to somewhere safely and continue investigating. In this case i believe it could have been some bad gas, or maybe a dirty injector from sitting in a box for a month or two while i got the new engine that caused a cylinder to misfire giving me that code, ive reset the computer and this code hasnt come up again. Thanks everyone for helping me get my charger back on the road :)
