SOURCE: FUEL PUMP FOR CHEVY SILVERADO

fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?

SOURCE: process to change fuel pump on 2001 chevy silverado 1500

take the six bed bolt loose and then take three buddies slide the bed back put in the new pump slide it back n place and put the bed bolts back in. if u drop the tank u can easily break the hard plastis lines that go to the fuel tank. u only have to take the fill lines and taillight wires loose this way its alot quicker, and easier.

code p0089 refers to fuel pressure regulator---performance problem===causes --fuel pressure regulator--- mechanical fault
check the regulator operation as it controls the operation of the fuel pump as well
At this point I would be considering a new regulator or checking any wires connected to it

2005 silverado lt 6.6 duramax diesel turbo..engine trouble code reads turbo low ???? when driving truck, stop to go up a hill, push pedle to the floor, no power and acts like not enough fuel to engage...


Before we do anything else lets do a fuel pressure check to make sure the pump is a-ok as well as the fuel pressure regulator. Your gonna need shop manual for this as well as a fuel pressure tester. If all checks out then move to the Turbo code.
Turbo code looks like the waste gate is stuck open and your not building the boost. Do a visual inspection look for any signs of overheating and bearing wear. Check or change oil as needed.
With regards to the Mass air flow I believe you have to replace it. Keep in mind this thing might be the root of you whole problem.
I strongly suggest you use the shop manual for the codes you got. it will make this repair a snap.

Service engine light on showing code p0089


Diagnostic trouble code P0089 - The ECM commands the Bosch high-pressure fuel pump to deliver a specific fuel rail pressure - that can vary up to 23,000 psi depending on load and speed. The actual pressure is monitored via the fuel rail pressure sensor. If the fuel rail pressure varies more than desired or if commanded fuel pump flow is 100mm3/second or less, DTC P0089 will set.

Corrective action includes measuring the fuel rail pressure using a Tech II scan tool, then compare that to commanded fuel rail pressure with the engine running at 2000 rpm. The difference must be less than 20 Mpa.

A blockage in the fuel tank or plugged fuel filter could cause this fault (excessive vacuum in fuel line). If there is less than 5 in Hg of vacuum when measured at the fuel pressure test port at 3000 rpm, the fuel pressure regulator could be defective, and may need to be replaced. The fuel pressure regulator (FPR) is a sub assembly located on the Bosch high-pressure fuel pump.
