I am getting no power to the fuel relay, does that mean the fuel pump is bad?

Asked by chrissy_22 Feb 08, 2016 at 11:32 PM about the 2001 Chevrolet Tahoe 4WD

Question type: Maintenance & Repair

The fuel relay isn't getting any power, does this mean that the fuel pump is bad and needs to be replaced?

1 Answer

I have an 01 Tahoe with 5.3. It would crank for just a moment before dying and you could NOT hear fuel pump come on with key in ON position. Turned out to be the battery. It has enough power to turn truck over but not enough to sustain ECM functions. New battery in her and she started right up. Before diagnosing as battery, I tested fuel pump, relay "ECM B" fuse and reset computer multiple times without any luck. Hope this helps and you don't waste time and money like I did
