I just replaced the fuel pump fuel injectors and more parts but today i went for a test drive and my truck died in traffic . i also read no bus on the odo meter . so i think my pcm is dead . not so long ago a member here i think Big Rob had an adress where we can buy a pcm for our trucks . Also my pcm is still the 5.2 . but i have a 5.9 and 46re in my truck . will this be a problem ? my truck was sitting for almost 7 months and now it sits again . Thanks
