Replacing the Rear Shocks


The following pdf document provides step-by-step documentation on replacing the rear shocks on a 2007 Honda Accord.



Fuel Pump – Current Waveform


The health of the fuel pump and its operating speed (RPMs) can be rapidly assessed by a quick look of its current waveform. The shape of the current waveform, pump speed and average current draw are good parameters by which to diagnose a failing fuel pump.  Details of the procedure and known good fuel pump waveforms are contained in the following PDF file:


Relative Compression Test


The relative compression test monitors starter current (via a current probe and scope) during cranking to get a quick gauge of the compression of each cylinder relative to the other cylinders.  This is a quick and easy test which can be used to check for any significant loss of compression in a cylinder.  More details, including known good waveforms are in the following PDF file:
