Dealer says its the fuel pump Update: Dealer changed fuel pump but did not install it properly, so after I filled my car up with gas, I started to small gas fumes and had to lower all my windows just to breathe. Once i got home, gas was leaking onto my driveway and a lot water was leaking from the engine area. Had to call the local fire department. They came out and set up a containment area and pull my back seat look at the pump. gas was leaking from the cap of the container that the pump is housed in. Dealer picked up the car this morning. This has been a nightmare and could have been deadly. I'm just glad I was close to home when I got gas. I still have a headache from the gas fumes.

I think this is the issue and fix: SERVICE BULLETIN:LSB-0015-10 NHTSA ITEM NUMBER:10034245 MFG Bulletin Date: 02/04/2010 Component: ELECTRICAL SYSTEM: SOFTWARE Bulletin Summary: LEXUS: TECHSTREAM ECU FLASH REPROGRAMMING PROCEDURE.

Did they have to replace your ECM?
