1991 fuel pump ecu
Does the 91 ls come with a fuel pump ecu? If so where is it located? I checked behind all of the carpet in the trunk and couldn't find it.

(p.s. and always start fuel pump quest with a look at the fuel pump fuse)

FYI
From Alldatadiy.com
"PURPOSE
The Fuel Pump Electronic Control Unit, located in the left rear of the passenger compartment, controls fuel pump output.
OPERATION
During idling and light engine load, the fuel pump demand is low, so it receives a lower voltage (about 9 volts) from the Fuel Pump Electronic Control Unit. During starting conditions, high speed and load conditions the Fuel Pump Control Unit delivers a full 12 volt signal to the Fuel Pump, which causes an increase in output. This signal is switched by the Engine Control Module."
