I have a 94 gmc sierra 1500 4x4. Im having problems with getting power to leave the coil pack. Its a clean truck with low mileage on it so its been pissing me off that i cant figure out why im not getting any fire. I've replaced plugs, wires, cap, rotor, ignition control module (ICM), coil pack and still not getting spark from plugs. The coil pack is getting power its just not leaving the coil pack. At first i thought it was a bad coil pack so i took it back and got another one, still doing the same thing. It use to start every once in awhile and idle rough 10-15 seconds if that and then stall out. Now it wont even fire it will crank and crank but wont fire. So if anyone has ran into this kind of problem or if anyone has any ideas please let me know. Thanks.
