Bob,



I'm having trouble with my EIS 6000 fuel pressure reading. I have the  

proper scale, offset factors, and resistor entered into the EIS for a  

0-30 setup.  It reads a constant 10.3 psi regardless of whether or  

not the fuel pump is on or not.  I've checked the continuity of the  

pressure sender across the terminals and it has continuity and a  

resistance of 6.2 ohms without the pump being on.  However, I have no  

idea of what it is supposed to read and how to trouble shoot the  

problem. Some hints would be welcome.



Thanks,



Sheldon Olesen

Try calibrating it off the plane, with air pressure and a pressure gauge 

hooked up to a regulator. then you can measure the resistance as a function 

of pressure and see if the sender is changing, or if the problem lies with 

the readout.

Hi Sheldon,

  

 Take another look at the EIS instruction manual, including any  documentation you got with the fuel pressure sensor itself.  You need to  change the offset value (I think, it's been two years since I did this) in order  to get a zero psi when there is no pressure.  It's in the instruction  manual, but you may have to hunt for it.  You can also call EIS; they have  always been eager to help whenever I called.

  

 Good luck,

 Dennis
