1999 Lexus LX470 4.7L No Start VIN: JT6HT00W8X

This one is fixed and gone. The problem was with the harmonic balance. The used engine came from a car that was in a frontal crash and had caused the tone ring on the balance to slip enough to advance the spark. We installed the balance from the original engin...

2002 Toyota Sequoia Limited 4.7L Stall VIN: 5TDBT48A22
Thanks for all the help. I replaced the ballast for the fuel pump and it roared back to life only for a little while. I hooked up the Modis and the wave form for the pump looked suspect. So I took it home for an extended road test and after driving it about te...
