Re: 5KCSTQ Hot Start Problem...the saga continues

[Colin Hames <cchames@mm.com>]

This is the exact same problem I had with my '87 5TKQ.  I tried the fuel
check valve, injector cleaners, pressure regulators etc.  The problem
persisted.  The fix?  The dealer tested and replaced all 5 injectors. 
They were all leaking down.  It was expensive - about $500, but the car
starts immediately every time, hot or cold.
