I've been having some odd issues with my truck. It started with my ignition. A few times as I turned the key the truck has started to turn over then stopped. After a while it comes on, but there's a heavy amount of white smoke from the tailpipe. It doesn't smell like oil. Also my ABS and Brake lights are constantly on. The truck runs fine but seems to be a little lacking in power. My knowledge in engines is very limited, so if you could use small words and maybe interpretive dance it would be great.
