Fuel pump getting power to the fuel pump

Check continuity of the wires between the relay and the pump.

If I understand your post correctly you have a fuse for the fuel pump that is blown or blowing. Until you resolve that issue the fuel pump probably will not get enough power to run. If it blows when you replace it the you have a wiring problem to your fuel pump. Most replacement gm fuel pumps come with a replacement plug for the fuel pump. Make sure you use it if yours did as there have been lots of problems with the wiring plug being damaged due to the high current draw of the fuel pump.

You have no voltage at 15 amp fuel pump fuse in the under hood fuse/relay center ? There is a fuel pump relay also in same under hood fuse box. The fuel pump fuse gets power from the fuel pump relay. The ( PCM ) engine computer controls that relay, gives power or ground electronically to turn the relay on giving power to the fuel pump through the fuel pump fuse. You could have a bad relay or an anti-theft system problem . What engine does you vehicle have 2.0 L or 2.2 L the 2.0 L engine gets power differently to fuel pump .

Get yourself a wiring diagram & study it & then
start testing the fuel circuit

How would you know whether you had power or
now power, to anything, working blindly?

You listen to what your told.
I wouldn't-- you may have changed a good fuel pump

I NEVER walk to any vehicle without a wiring diagram

How would you learn the system & the circuits, without one?

check the pressure sensor in the fuel manifold as it directs power to the CPU to turn on the fuel pump

Does the car have an immobliser fitted if so it may have cut the power to it? Have you checked the inertia switch that maybe faulty? Check power at the fuel pump fuse and at the relay!

the fuel pump is supplied power via the fuel pump relay. The relay gets power for the fuel pump through the ECM B fuse. This fuse also supplies power to the vehicle control module.

The fuel pump fuse gets its power from the fuel pump relay, which is located in the Instrument Panel Junction Block.

The fuel pump relay gets its ground from G102, which is located just forward of the left strut tower.

The fuel pump relay gets its power from the Powertrain Control Module Connector "C" Pin 10 ( DARK GREEN/ WHITE wire) for the primary side of the relay.

The sencondary side (the side that provides power to the fuel pump fuse) of the fuel pump relay gets its power from the IP BATT Fuse (30 Amp) HOT AT ALL TIMES in the underhood fuse block.

This should be enough information to figure out why your fuel pump is not getting power. Let me know what you find.

check fuel pump relay on firewall passenger side if it has power and power when the key is turned on will click test power through relay to fuel pump disconnect connector at fuel tank make sure you have a good ground test for power at sending unit when key is os or in start if power the sending unit has rotten corroded wire going to fuel pump you will have to remove the fuel tank test power right at the pump if there is no power replace sending unit if power a pump use teslight one end on ground terminal and other lead on power terminal at pump if you have power replace the pump

if this is helpful plz leave a comment like and if you need more help ask once you eliminate pump good luck

The pump gets it's power from the fuel pump relay under the hood driver side fender well there should be three relais under the plastic cover there is a windshield wiper motor relay a fuel pump relay and i forget the third but swap relays around and see watch you get
