09 yukon fuel pump fuse

Appreciate it! Going back at it this afternoon, will report what I find.

Just wondering. Did you run your tank empty, or very close to empty recently?

No, I try to keep it at least half full...it ended up being the fuse for the fuel pump control module

If I look at a 2010 fusebox, it looks like the fuse for the fuel system control module is in position 21, to the right of the fuel pump fuse. Not sure if yours is the same. Have you checked that one? Also, it would be good to probe both sides of the fuses to verify voltage through them.

Do you know if you have fuel pressure?

Finally got time to get back to the truck. You got it! The fuse for the fpcm was blown. Replaced it and fired right up. Unsure what would cause both of those fuses to blow, so not sure yet if it will be a recurring problem. Thanks for your help!! I like this forum and will contribute when I can!

You said "cranks but no fire". Are you saying no spark or you did not check that? You need to check for spark and get a fuel pressure reading.

Ended up being a separate fuse for the fpcm. So both the fp and fpcm fuses were blown. Running for now, well see if it happens again...thanks for the input!!

Great, all is right with the Tahoe/Yukon world again, at least for you anyway.

Ok, I'll bite. What does Hozro stand for?

Harmony and balance.

Ok, love it. Is it just another way to say, "Harmonic Balancer"?
