So I’ve completed the holy trinity of fuel pressure-related hot start issue fixes:
New Fuel Accumulator ✓
New Check Valve ✓
New Primary Pressure Regulator O-Ring ✓
...all to no avail. Nothing’s leaking, the car starts just fine cold and runs well too. But if it gets warmed up and turn it off it still refuses to start back up until it’s completely cooled down again.
So - if it’s not a fuel pressure problem, what else could it be? OR is it still a fuel pressure problem and there’s something I’m missing?
