I have 2000 ford mustang 5 speed v6 3.8l. It has 135,000 miles. Did the Oil changed, Front and back breaks changed out the rear suspension and everything seemed okay. The other night was driving back from work. We had a real bad rain storm and the humidity was horrible. I was driving down the highway doing about 60. The car starts making this weird chattering noise under the hood. Sounded like the serpine belt was smacking under the hood. I pull over lifted the hood while the car was running and still heard the noise but the serpintine belt was fine. The car was sounding really ruff so I turned her off. When I look towards the back of the car its smoking dark thick smoke out the exhaust. I smell this sweet smell coming from the car weird stuff. I check the fluids everything good. OIL FINe, ANTI FREEZE FINE, NOT OVER HEATING. Battery lamp good. WEIRDEST thing ever happened to me. Make a long story short car wont turn back on. It wont turn over or nothing. sounds like the car is shocking itself when I turn the key. The batteries dead now but was okay before I worked her over a bit so thats probably my fault plus the alternator is new I put her in myself. What died Timing chain, seized engine, something locked up in that car cant put my finger on what it was though. Please help.
