I’m getting the classic low voltage at fuel pump code
Things I’ve done
Used two different fuel pumps , same results
Elimanted my tuner , same results
Cleaned all my connectors, same results
Now I’m getting no power at fuel pump
Fuel bowl dry
I changed the fpr, about 5 to 6 years ago
I’m lost
Every time I changed the pump I get less and less voltage

I’m not getting any injector codes like ipr or ipc

Ya I’ve tried looking for it
I looked behind the radio with no luck just the blue relay for turn signals
It’s a 2003
All I have is the fuse box
There is four relays right behind the air box location next two the master cylinder
Two black boxes with two relays each , not sure what they are
I’m guessing the fuel pump relay is part of the fuse box under the steering wheel and it’s none serviceable

Reset switch down by the passenger feet area ? Or bust out the owners manual and see which fuse on the panel
is linked to the pump. #40 maybe ?

I’m thinking the fuse box **** the bed
I replaced the EEC relay ( powertrain relay ) and nothing changed
Prior to the fuel pump issue
I was having window and radio problems they wouldn’t work for the like the first 20 to 30 seconds after start up or not work at all the whole drive
Random abs light too
Also the glow plug module was throwing a code

Holy crap. Id say so.. interior issues like that point to the gem.
