I'm currently not getting any power fed to my ignition coil. What I have done so far clean all grounds, test all the fuses, tested cps and replaced and test the battery. Not to sure where to go from here other than looking for shorts in the harness. Cant make a connection with obd reader tried unplugging the cps and trying again and still no connection. 96 Grand Cherokee Laredo 4.0 2wd. Any help would be greatly appreciated need to fix soon.
