04 Tahoe not starting right away... HELP!

[nkosmo]

Hey guys. My 04 Z71 has not been starting right away, but starts on the second crank of the key. I replaced the fuel pressure regulator ($115!) and that did not help. I'm, thinking i probably need a new fuel pump. What do you guys think?

If you can check fuel pressure to verify that there is no leakoff after you shut the truck off that would help......does it run fine once it is running?

YA, test fuel pressure.

I think the connection (shraeder valve?) is on the right(?) fuel rail.

fuel pump for sure. grab an ac delco one and call it a day. find your correct part number on rockauto.com and google it to find the best price. i usually find the best prices on amazon even with rockautos 5% discount coupons.

Thanks guys. Yes, it runs fine once it starts. I'm going to check fuel pressure this weekend,

Always check the pressure before you start to toss money at it. You spent $115 for a regulator you didn't need.

Would do like said above. But also check fuel filter. Could be clogged up.

Replace fuel filter with the pump as it is usually required to warranty the pump should it go bad
