Hello every one, just ran acorss this fofum and wish I had seen it soooner. Looks like a lot of help here. I drive a 96 tahoe 4dr with 5.7, 250K mi and running stong. I drag a 24ft trvel trailer every onth into the mountains and I am very please with the truck. This past week though it left me stranded. SES light gave code P0171 and P0174, lean bank 1 & 2. It was very slugish once it did start, got it home and through trouble shooting found fuel pressure was only 22psi. I had replaced this fuel pump about 5 years ago with out dropping the tank by going through access panel i installed under the back seat( not third row). Dropped a new pump in and pressure right back to 60psi where it shold be.
Just a heads up if you run into a no start or hard start 5.7. Tak to you all on the forum.
Ride safe...
