Diagnosing the problem comes down to understanding what causes a loss of fuel pressure.
Here is a diagnostic puzzle: An owner comes to your shop complaining that it takes longer than expected to start his car’s engine in the morning. There are no codes for the crankshaft and camshaft sensors. And, the oil pressure is within specifications. If you are lucky, you might have a code for low fuel pressure on the high side of the direct injection system. What could be the source of the problem?
New vehicle ADAS features all rely on the alignment being exactly as it should be.
PCV systems control crankcase pressure.
When a compressor fails, the question for most technicians is whether to flush the condenser or replace it.
