Re: [DML] fuel pressure tester

What were the symptoms that made you think to check the fuel system 
pressures? In many cases the symptoms can tell you what the problem is 
without the need to actually check pressures. In some cases it is 
helpful to use the gauges to confirm the diagnoses but not required. 
The fuel pressure accumulater causes hard hot start problems when it 
is bad. Although other things can also cause this there are things 
that can be done to confirm a bad accumulater without resorting to 
gauges. A bad or missing check valve on the fuel pump might be causing 
your system rest pressure to crash. Replace the fuel filter and cut 
the old one open, if it is full of black chunks the accumulater is 
gone. (An accumulater 2 years old is not immediatly suspect). A fuel 
pump may not be bad if the suction hose is collapsing causing the 
pressure to fall. Using gauges requires you to interpet the results 
correctly.
