Alright so usually I can figure out what's wrong with my parents trucks. But here's the problem. Dad truck stopped running fuel pump went out. Replaced the fuel pump it won't start so we replaced the fuel pump relay, still wouldn't start tried a brand new cam sensor and now it's back firing through the intake after a few rotations. It wasn't doing that before hand. The only other thing that crossed my mind was the way the distributor is with how it crosses a cross itself multiple times on the cap. My buddy said it could be the crank position sensor also but I hooked up my programmer to it and got a p0300 code which is a multiple miss fire.
