Get the codes pulled, that will tell you where you have to go next. Most auto parts stores can do this for free.

What do u mean by get the codes pulled

78,065

There are codes that have been stored that is why the check engine light is on and or flashing, the parts person will know where to plug in and get the codes, make sure you write them down, then repost back here.

the code says random multiple misfires

OK Try this: locate the ECM fuses, make sure you get all of them including the KAM fuse, and pull them out, make sure the system is without power for at least 30 seconds to 1 minute before reinstalling them. Or if not concerned about loosing presets then you can disconnect a battery cable, turn on the headlight switch for the same amount of time, turn it off reconnect the battery cable, start engine and drive it as you normally would watch for check engine light, hopefully it will not return. If it does come back with the same code, try ohming the new coils, there maybe one or two out of specs even though they are new.

I tryed pulling all of them fuses that didn't help it didn't even reset it do I thought I did it wrong took the wires off the battery then turned the lights on and it still didn't reset anything

Then your alternatives are electrically disconnecting the ECM wait overnight, then hook it back up and start the engine, if the check engine turns back on with the same codes then you need to start measuring the ohm's on each coil and replace those that are out of specs. Or take it to a shop you trust and have it checked.
