You need to do some diagnostics like check for codes, CC test, balance test, maybe even compression test. You said smoke smell was distinctive, is it fuel? I would assume so. Are you low on power? Does the engine have a miss to it?

Without this information, everything is just a guess.

Check fuel pressure also.

Also loss of power and sounds to have a slight miss! When cranking over it seems to hit then crank hit then crank but it will start up and when u first start it it wont knock or smoke then after about 30 sec or so it starts knockin and smokin! Its definately fuel
