I pulled P0302 code #2 cylider so I assumed it was the coil pack, got a new one replaced it now it wont start. My friend said its my cat since ive been riding with the p0420 code for a few years guess its time to move on.

 

the code wont stop your car from start, there is something else wrong. Does the car turn? if it doesn't look at wither the battery or the starter. Start there.....

 

put the old coiloack in & try to start it... if not working switch cylinder 2 & 4 coiloack to see if it starts. Clear the code and see if the CEL comes on for P0304 cylinder 4 misfire. if it doesn't follow it, check the plugs and connector wires for cleanliness

 

Misfire will not prevent your car from starting. Your problem is elsewhere.

 

Agreed.

OP, does the car crank like normal? Or no crank?

 

It cranks. I forgot I have a fuel gauge issue might need gas I'll get some later.

 

lllmmmmffffaaaaooo!

 

Thanks for a waste of a thread.
