i should also add that my problems were progressive over a year time frame and it started with just intermittent trac off lights w/CELs and no hesitation and then as time went on it started hesitating and dying when those lights would come on. for weeks it would run amazing and then out of the blue it would have a bad day. as time went on these things started happening more and more until it finally just shat on me all together and would not stay started. that is when i noticed the fuel pump constantly running problem. sorry so long of description but i know the one thing i wanted when looking through these forums was more details and every forum with similar problems as me would end before the problem was posted. it was very frustrating.

Sounds like an ECU issue to me.
Have you read "all my crazy Lexus issues SOLVED!!" ?

Yes That was one of the last threads I came across before I bought the new reman ecu. This was a tough one to crack because my ecu, maf, and starter all went out out at basically the same time. Sometimes when I would try and start the car I would just get a click sound and then nothing but if I turned the key back and forth several times it would finally start. I just changed the starter and that solved the problem. Multiple system failures are no fun especially on the wallet. I'm glad there is a large following of lexus vehicles. Forums like these are really a lot of help!
