maybe it needs a new plug..... make sure everything is connected (coil)

 

I'm not sure what the problem would be... I would also go with double check your connections.... But DON'T EVER sell that truck... If they decide not to bring the Lightning back, it's only going up in value... I found my father dead in mine... everyone wanted me to sell it.... Hell no.... I coveted that truck for years... Not quite the way I wanted to get it... but now I have even more reason to keep it... Don't ever sell it...
