If it runs rough when started it could be the distributor cap and rotor. it could also be water in the gas but that would usually mean once started it dies again. Finally, when you start is upon cranking if it doesn't sound normal you could have a burnt valve. I would first do a compression test just to rule out something major, if compression is ok then start with the cap and rotor, perhaps wires also.
It would not be the crank sensor or fuel pump as when they fail they fail and if the car starts sometimes then it would run normally

Rattleing and knocking noise in engine when running. Fades in and out.

Sounds like a main or connecting rod bearing is starting to go.Need to be more specific of when and how often it dose this.Also how many miles on engine.If your talking 100,000 or more its definitly a bearing.The more your run this engine (if its a bearing) the more damage your doing.Either way it dosent sound good.If this is a 350 or 305 engine if the oil wasent changed regularly these engines are known for bearing knocks.

Every time i put a new muffler on my 1997 jeep grand cherokee the motor bakfires and blows the muffler compleatly apart it dosent do it right away it runs fine for a few miles then boom then it starts to...

What a funny set of events.Of course the tail pipe is clear(you would have checked that)The only other thing it might be is the cat/converter is blocked.New muffler is allowing a heap of air through and it suddenly clears and the bang.They do block up so it may be worth getting it checked.Hope this helps

87 760 turbo volvo. wont turn over. it will act like it but dosent. if it dose turn over and start it will run a bit spike to 3k rpms then die out. fluid lvls ok when it dies it shakes violently

Check starter connection. Mine does the same thing. Also check belts. A pressure hose could be unattached. Right above the starter there is a hose. Check all of them to make sure they are hooked up.
