does anyone know when checking an LS1 coil pack, what the resistance should be across the primary terminals (terminals A & D i believe). trying to test my coils and cant read the ecu rite now to try the switch coils thing, I just wanna test the coils first. Any help would be appreciated.

 

Coils should have little to no resistance.

 

and if they do have some..... they are bad? i mean alot? because i know the plug wires have around 300+ ohms of resistance.

 

The plug wires are different then the actual coil. I dont remember the actual resistance per foot that the wires should be offhand.

 

stock wire for LS1 6 in. - 351 ohms
