    340lph Fuel Pump Issues

    I installed a 340lph Quantum fuel pump last night into my 1999 K1500 Suburban Delphi canister. The install went very smoothly and I decided to pull the brass venturi pump barb out of the delphi pump and install it into the new pump. It works very well, but it is sucking the bucket dry after WOT...

    95-00 Gauge Cluster Font

    Does anyone know the name of the font, or at least a font similar to the one used on our gauge clusters for the numbers? I am looking at ordering a Speedhut transmission temperature gauge since I can order one with red backlighting and a clear needle to match my esky gauges with red leds. I...

    P0300 2005 LQ4

    I have a 1999 K1500 Suburban that I swapped a 2005 LQ4 6.0 in. The engine has new acdelco 41-110 spark plugs, MSD Superconductor wires, green intake manifold gaskets, and stock coils and injectors. Last night coming home in heavy rain it started to misfire really bad and the CEL was flashing...

    Lq4 Swap Fires but Won't Stay Running

    I have a 1999 K1500 Suburban that I did a Lq4 swap on. When I went to start it for the first time, it fired and the dies. It'll do that every time, sometimes running for a little longer, but no more than maybe a second or two. I wired it according to Lextech's file, and previously had a 0411...

    Steering Box

    I am looking for a power steering box for my 1999 Suburban K1500 5.7. I found one that says it will fit a 1996 K1500 Suburban and up to a 1999 K1500 Silverado, but not a 97-99 Suburban. Was there any changes to the Suburban steering box through these years? I messaged the seller and they said it...

    Engine VIN Number

    I recently purchased a LQ4 from a 2002 GMC Sierra 2500hd and I was wondering if it is the original engine or not. Looking at the engraved numbers on the drivers side of the block above the oil filter it reads "A37205 2914". None of that matches the VIN from the truck I pulled it from. I'm trying...

    96-Up Fuel Delivery

    Im researching as much as I can on doing a ls swap before I start collecting parts. I've gotten pretty much everything figured out I believe, except for the fuel delivery. My vehicle is a 1999 K1500 Suburban, currently with the L31. What I'm wanting to do is run a 99-02 intake with the return...

    1999 Suburban K1500 4l60e slipping

    Yesterday when driving home from school I accelerated to pass a car and it downshifted to 2nd with no acceleration at all. The fluid is still pinkish red but was burnt smelling. So after a little driving and seeing where/how it's slipping, it slips in 1st and 2nd after 3000 rpm. Im sure it...

    94-00 Chevy bowtie adapter to 2014 style bowtie

    I am currently taking a solid modeling class and had the idea to create an adapter to be able to use a 2014 up Chevy Spark bow tie in place of the factory 94-00 bowties. The one in my grille fits okay but I'm wanting to make it look more factory by filling in the gaps. I'm going to take...

    Jet programmer for 96-00 l31

    I came across a Jet programmer for a l31 for a really good price, considering that they're normally around 300 new. I was wondering if anyone has any experience with these and how good they work. Sent from my SM-S920L using Tapatalk

    '99 4l60e Rebuild and Upgrade

    First and second gear are slipping in my 1999 K1500 Suburban and my fluid is burnt so it looks like I will be having my tranny rebuilt soon and replacing the rear main seal while it is out. I am looking at having the Transgo HD2 shift kit installed at the time of the rebuild. Is anyone running...

    1999 L31 Misfiring

    I have a 1999 K1500 Suburban with the L31 5.7 and am having some misfiring problems around 1500-2000 rpms under load. I used the dash command app and seen that the cmp was at 3 degrees so I set the distributor so that it read 0.3, which is as close to 0 as I could get it. Now it is misfiring...

    Keep K&N or sell?

    I have a K&N cai for my 99 5.7 suburban that I took off. I replaced it with the factory intake and deleted the vortec box and did the tb blade mod. Since I haven't been able to sell it I have been thinking about putting the K&N back on. Does anyone have a dyno sheet of the K&N compared to the...

    P0174 and P0171 99 5.7 K1500 Suburban

    Just had these two codes come on today. I just had my two catalytic converters replaced about a month ago but I don't think it's related to that. I have had a vacuum leak on my brake booster, whether it's the booster itself or the line going to the intake manifold. Would this cause the code to...

    Upper Control Arm Alignment Punch Out

    I recently installed 2" blocks and cranked my t-bars to level on my '99 K1500 Suburban. I called the alignment shop about having it aligned and he said theres holes on each side that have to be punched out to allow more camber adjustment since i raised the front end. He quoted me at $130-150 to...

    Throttle Body Blade Mod Help

    So I did the throttle body blade mod to my 1999 5.7 Suburban by drilling out the rivets holding on the plate with the lip on it. Not thinking, that left two holes meaning more air is flowing when the blade is closed in the tb. Now my truck idles at 1,100 rpms. Is there a way to plug these two...
