I've had it for about two years now, and didn't have this problem until recently. At one occasion after a long trip it wouldn't start after parking for a few minutes.. the next morning it fired right up. A few months went by with no trouble until last weekend; I drove it to work all week and then on Saturday it fails to start and hasn't since. Turning the key over I have lights, radio, the starter spins , etc. I do have pressure from exhaust while trying to start as well. What do you think is the issue?
