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