5.9L Cummins (2003-2007.5)
My 03, has developed a wierd staring problem, it won't start when it is cool or cold out, cranks like crazy, no fire.
However if I plug the blockheater in for 45min, she will fire right up. Once it is running it works great, no smoke, lots of power, runs real smooth.
Everthing I read says...
