Re: [DML] Fuel Pump Problem

["Marv Hein" <marvhein@xxxxxxxxxxx>]

Corey,


Chris is right, if you have a voltmeter and a large paperclip for the 
RPM relay jumper, it won't take long to diagnose.  

In case you don't have the manual for the car, maybe this will help.  
I spent a long time tracking stuff down, even with the manual.

1) I can't recall if fuse 7 is numbered at the fuse box but it is the 
middle fuse in the row closest to the front.

2) SpecialTAuto.com has a good diagram of a jumper for the RPM relay 
and a photo of the relay itself.  This relay is the farthest to the 
rear of three large relays that extend from front to back.  The front 
one is located just aft and left of the fuse box.  My RPM relay hangs 
at the end of a extender wire... not sure they all do.

3) The inertia switch is on the left wall under the driver's side 
dash. 

4) If you need help finding any of this stuff, feel free to drop me 
email off-thread and I'll walk you through it on the phone or I can 
send you some digital photos. 

I just went through all of this myself and it did prove to be my 
pump.  If it also proves to be your fuel pump and it's pretty new,  
you might consider a heat shield between the radiator and the fuel 
tank.  I nearly lost my new replacement pump the first week due to 
overheating due to radiator air drawn by the fans heating the gas 
tank to extreme temps. (I put a temp probe on the tank and saw it 
happen.)  A shield has really cleaned that problem up.
