so basiclly my car stalled the other night, wont start, towed it home, did all the usual inspection and then i plugged in my scan tool....It's showing a fault code of P2301 and P2304......these codes indicated that "ignition coil A & B primary circuit high"......i was just wondering what this means and how it can be fixed. A couple years ago i had spiliced into some wires for what reason i dont remeber, but why would it be affecting it now? i checked all the fuses and none are blown.....i had an MSD coil pack but once this happened i reverted to the stock one....also have 8mm upgraded wires and iridium plugs, but that cant be the problem.....



thanks in advance for the help

 

Late as ever, but I'm having those codes right now. Car won't start despite new fuel pump/filter, and plugs.

 

 

usually it's a coil failure
