Re: alfa-digest V7 #1303 - Fuel Pump Testing

[AlfaNeely@domain.elided]

    To test a Bosch fuel pump, I normally just lay down beside the car and 
put my hand on the pump.  If it vibrates when someone tries to start the car, 
it is working, or trying to work.
    If it does not vibrate, the first thing to check is the fuse.  The fuse 
for the spider fuel pump is under the package tray behind the passenger seat. 
 It is on the outside of the injection computer in a fuse holder.  I normally 
replace the fuse holder with a new one from any parts store.  I also up the 
amperage of the fuse a couple of amps.  The stock fuse seems too low in amp 
rating.

 Subject: how to test fuel pump
 
 How do I test the fuel pump on my 88 Spider?
 
 Here is what I have done so far, Is this correct?
 
 1. Put key in ignition - turned to on posistion
 2. move flapper valve in AFM to activate the pump
 3. No voltage at pump.
 
 I have no checked the relay yet because of something odd.  When I
 checked the fuel pump, I placed a voltmeter between the two terminals.
 I have no voltage, but I have continuity between the two terminals.
 This isn't correct is it?  Or does this mean that something went bad
 inside the pump?  If I check each of the terminals for continuity to
 ground I find that each terminal independently has continuity.  Does
 this sound like my pump is bad?
 
 Sorry if this is simplistic, but I am still learning.
 
 Thank you.
 Kelly M,
 88 Spider - hopefully running again soon.
