Tarnold,
Glad you got it going.
You have a vocabulary problem that if you fix it, it will help others help you. I have done a lot of long distance diagnosis and this is not nearly a unique issue with you. Please read and remember the following:
Doesn't crank means that you hit the start and nothing at all happens.
(Hit the key and it goes "click, or click, click" - bad battery or connections.)
Cranks but does not start means the starter motor is turning the engine over, but it will not start or even fire.
Starts, but will not run, means that the engine will start, but quits shortly after you let go the key.
The above three are all very different cases and have different causes.
Other than those.
If the coach makes noise moving, try to determine if the noise is engine speed or road speed related.
If the brakes make noise, the above still counts, but does the noise get louder with more brake pressure.
Any of these will help you get a better and more applicable answer.
I am an engine guy and have been for years. I didn't contribute before because I couldn't figure out what you were trying to say in the time I had available to read ans answer you.
