    09 Tahoe engine dies at stop, no CEL

    Since the general consensus was fuel pump, I ordered one. Dropped the tank & found charcoal in the tank & all around the pump after it was supposedly cleared by the shop. So, I also bought a new charcoal canister. I fully dried the tank, cleaned it out completely, checked all the lines & the...

    09 Tahoe engine dies at stop, no CEL

    Haha...you're not telling me anything I haven't already thought about, sorry Debbie...lol. I'm just trying to be as certain as I can before cutting the check on the part and expending blood & sweat on the swap.

    09 Tahoe engine dies at stop, no CEL

    I agree the fuel pressure test doesn't carry any weight. It just shows it was working normally at the time of the reading and right now it's a sporadic issue. General consensus is the pump on this forum, just trying to be as sure as I can before dumping that much money and the blood/sweat into it.

    09 Tahoe engine dies at stop, no CEL

    I think the slow starts in the past were a bit of warning shots, then the stalls were the fix it message. The pain in the butt part is it being sporadic so as we know that makes the diagnosis harder. I appreciate the input.

    09 Tahoe engine dies at stop, no CEL

    Well it's never been run dry, at least not while I've been driving it. Can't speak for what may have happened at the shop but that was maybe a year ago so if it fails that quickly after a dry run, I'm going to guess that isn't the issue. It may just be the fact of an age thing and again, me not...

    09 Tahoe engine dies at stop, no CEL

    I'll have to check the trim. The live data gave a fuel psi of 58 when I first started it and it was idling at around 1250 rpm. It dropped to 43/44psi when the rpms dropped to the normal 750. If I get a chance to look for the other data I'll let you know what I find.

    Nav system issue

    I have tried going into the settings with the pin code & set it to GMT. I've set it from the settings screen. It always reverts. It also will not stay set on the 24hr clock. I have disconnected the battery & let it sit for 30 mins to try & do a hard reset. No luck. I haven't done anything to...

    Nav system issue

    I've seen some threads on here but they are older and I didn't see any solutions listed. The factory CD/DVD/Nav head unit in our 2009 Tahoe LTZ will not retain the search region when I set it. We are in region 10, Florida. When I set that region the system resets to I think region 1, I'd have to...

    09 Tahoe engine dies at stop, no CEL

    We have a 2009 Tahoe LTZ with the 5.3L Flex Fuel. It has about 45k miles so very low mileage for the age and it's been well maintained. In the past few months we've had a few times, 3-4 where we experienced a long start. The starter turned way more than normal but once it started it was smooth...
