I have attached a zip file of a noise that my engine just started making today. I hope the file can be opened and is clear enough for some answers.
It starts out sounding like a screeching noise almost like compressed air escaping. As the engine warms up, it tones down to a rhythmic ticking sound that fades but will not go completely away.
Here's the kicker...On two separate occasions the engine would not start. I turned the ignition key to start and all the dashboard lights lit up but there was absolutely no engine response. The starter did not even click like when the battery is too low. Left the Jeep alone for a while and it started up with that awful sounding noise.
Engine coolant is not overheating. The battery is fully charged. There is sufficient oil. The automatic transmission did not overheat. There have been no DTS codes. 30,000 miles on the odometer. Putting the transmission into Drive, Neutral, or Park makes no difference. But the noise will fade as the Jeep warms up.
Any help on this would be greatly appreciated. I have a 2 week trip planned that would start this Friday and the timing of this noise just sucks.
