I have a heavy fuel smell after I turn off my car. It is only outside the car.

Thanks Pat, I looked deeper and found a leak. I decided to pull the fuel tank and have a good look before driving the car anymore. I found that the gasket had failed to the fuel pump. The green one. Went to GM and bought a new one for 25.00 tax included and fixed it myself. Thanks alot for the advise on the 2001 L300.

Pat, I saw your reply on this post perhaps you could help with another that hasn't been answered. I have a check engine light that won't go off and I have the battery disconnected hoping to reset the computer. I replaced the MAF sensor last night. However I also have had the transmission shift hard at times when the check engine came on. There was an post about this exact thing that wasn't answered and I wanted to know if you could help. Thanks
