Burning Plastic/Oil smell from 2005 Ford Mustang?

I just had my fuel pump replaced about a month ago in my 2005 Ford Mustang and now I've begun to notice a burning smell when I get out of the car or roll down the window in a drive through. The smell reminds me of burning tar when they repave the road, which initially I though was due to the 110 degree plus August weather in Las Vegas melting the tar patches on the road. Now, I am noticing it every time I step out of the car, so I think it is coming from the undercarriage. Any ideas?

    Check the exhaust. I had a plastic bag melt onto mine. It took like 2 months of driving to get the thing to finally burn all the way off. I tried to remove it, but it was like epoxy so I decided to just leave it.

    You should immediately check ALL belts and hoses in the engine for cracks and wear. These are made of plastic and rubber and can give off an odor when they weaken from --age or --intense heat exposure. They then give off a streety rubbery burning, almost smoldering smell when ever the engine warms up. Good luck.
