I have a 96 2dr hoe and i just replaced the lower intake manifold gasket. i had no issues with that but when i went to start the truck i had no spark. i have spark at the coil, but not at the plugs. i assume that it is either the disbutor because the cap and rotor still looked in good condition. the truck has about 150,xxx, just wondering if there could be something else that would be giving me this issue.
