This truck has been sitting for about 1 1/2 years and it always started right up as I only started it once every year. It has a 318 automatic. It did not have spark at the spark plugs at first but then I switched out to a different coil and still did not have spark. Then I jiggled and reconnected the bulkhead connector at the firewall and it then has spark at the spark plugs. I have been pouring gas down the carb and cranking it over but it will not even catch or fire once. Did this for about an hour or so. I never pulled the distributor cap off or did anything else as this truck always fired right up after sitting for a complete year every year. What would be causing this? Snapped cam from the extreme cold winter this year? Timing somehow off? Like I say I just fire it up once every year drive it around on property little bit then park it.

Thnks,

Wizard
