Fuel tank, fuel pump and fuel filter have all been replaced with new. Currently will not start or run. When it did run, sounded like a misfire, black smoke and burning smell coming from exhaust. Service engine soon light stays on. OBD2 tester says engine misfire. Could it be as simple as changing spark plugs? Or could it be one of the many fuel/oxygen sensors? What is a "spider" in relation to this? Whom ever reads and thinks they can help, please do. If you need more information please contact me through this medium. Thank you.
