    2001 Yukon slt 5.3l won’t start after front end collision. Has spark, fuel and power at injectors

    Check the ground wire that attaches at the driver side radiator support mount pad or the one on the drivers side engine block to the fuse box.

    Looking for Summit White Handles and Mirror Caps.

    Rustoleum white in the rattle can is a near perfect match to Summit White if you want to just sand and shoot your own mirror housings and door handles.

    Gauge Cluster

    I bought the repair kit on Ebay for 20 bucks, came with 5 new stepper motors and some bulbs; even a soldering iron if you don't have one. Took about 30 minutes to replace the 2 bad stepper motors I had so I still have 3 motors left over, if you do it this way you don't have to have the...

    Alignments Suck -- What Am I Missing

    I get the steering wheel straight and locked (if there isn't a steering wheel lock notch that holds it dead straight I have someone sit in the car and hold it there) then adjust the drivers side tie rod until the drivers side wheel is straight ahead, then adjust the passenger side tie rod until...

    Engine additives, fuel treatment and oil

    I use the cheapest gas I can find and synthetic 15/50 (Napa brand because it is always on sale) and Lucas semi synthetic racing oil in the transmission; I change the oil at 10,000 miles and the transmission every 75,000 or so. 2004 Tahoe 5.3/4L60 has 317,000 miles 2004 GMC Sierra 5.3/4L60 has...

    Brakes get stuck

    I would pull the ABS fuse out and see if it still does it, if not stop spending money on the booster/master cylinder. If it does persist after the Abs fuse is pulled then start by flushing out the power steering fluid and replacing it with new fluid; you may have some moisture in the power...

    Fuel Pump?

    A 99 should have 4 wires in the fuel pump harness, it won't have the flat 4 if it is original but the square plug that needs to be cut off and spliced to the new style flat connector should have 4 pins.

    Shocking discovery

    It looks like a previous owner had nerf bars that he removed but did not put the bolts back in, or maybe the bars were stolen and nobody thought to crawl under to see if the thief was courteous enough to put the bolts back in :)

    ABS to conventional brake conversion.

    Removing the ABS controller means a lot of replumbing and will net you no additional reliability, pulling the fuse prevents all of the actuators from moving and the fluid just flows to the brakes as any non ABS vehicle would; no loss of reliability. I would also leave the hydroboost, they are as...

    I hate to compare.... Chevy 5.3 vs Ford 4.6

    The thermostat begins opening at the stamped temp and is fully open 10 degrees warmer than the stamped temp, most factory thermostats that I have pulled were stamped 195 but a 187 and a 175 are both available at any parts store. The thermostat is using the water temp at the thermostat housing...

    I hate to compare.... Chevy 5.3 vs Ford 4.6

    The 4.8 made emissions standards in 2002 without EGR but I think it took a couple more years for the 5.3, by 2005 when "Displacement on Demand" was the standard I believe all displacements were EGR free. DOD is a variant of VVT; they both alter the cam performance (albeit in different ways) to...

    I hate to compare.... Chevy 5.3 vs Ford 4.6

    I guess I should explain why I posted that info about the different specs of these two grades beyond the obvious. VVT is primarily used to eliminate the need for an EGR valve to meet emmisions and economy standards, the valve overlap is altered so the time that the exhaust valve is opened...

    I hate to compare.... Chevy 5.3 vs Ford 4.6

    I just googled Coquihalla Pass and the highway department reports the steepest parts at 8.5 percent, this is much, much steeper than any part of the Grapevine and is most definitely not a valid comparison to judge which engine is performing better.

    I hate to compare.... Chevy 5.3 vs Ford 4.6

    Firdtly, 212 degrees is not "hot"; that is about what the thermostat is set to run at on a 5.3 Secondly, the Grapevine is between 5 & 6 percent at the steepest points Southbound and 5 percent is the maximum pull Northbound; I am not familiar with the other grade you mentioned but if it is 7...

    Wet passenger floor in my 05 Tahoe

    Is your passenger presence system light on even when you have a passenger? It could be the sticky gel leaking out of the bag under the passenger seat cushion. It would be yellowish and sticky.

    C5 is going away, I bought a rust free black on black 08 Tahoe!

    In Kalifornia we have floods, fires, streets piled with human excrement, falling overpasses and bridges, a power grid so decrepit that we have to shut off millions of customers whenever the wind blows, the worst roads in the country and the highest poverty and homeless rate in any 1st world...

    Have a weird noise when I'm driving, wondered if y'all might be able to help me diagnose it

    X4 on the wheel bearings, I usually change both when I lose one (the right side always seems to go first) ; resist the urge to buy the discount bearings and go with the Timken. They are pretty quick and easy to change but still not worth multiple times to get the life that one set of Timken's...

    Lookee Lookee at this Silverado

    An empty 53 foot dry van weighs 12,000 pounds, he was using a converter gear so there was very little tounge weight, the hitch was plenty secure if the trailer was empty, he had brakes and lights functioning and I bet he had a commercial driver's license. So what exactly was he ticketed for...

    Misfire triggers armageddon!

    Add my vote to an electrical issue, bad ground or poor connection in a harness; possibly a loose plate in the battery that causes your "Armageddon" when it drifts over enough to touch another plate.

    Emmisions test required

    In California you can pass with the evap readiness monitor not ready as long as the rest are complete and the check engine light is not on. If you Google "gm drive cycle" you can set the monitors in about 10 miles from a cold start but you need a road with light traffic.

    Tesla Cybertruck

    Battery operated vehicles are not cleaner, cheaper, safer or more practical than vehicles powered by internal combustion engines; they are good for children's toys and making those with no grasp of physics feel relevant.

    Refurbish or Replace

    I ran my 04 Tahoe to 265 thousand miles and the gave it to my niece 3 years ago (she's still driving it), I replaced it with a 03 Suburban with 200 thousand miles but like new; my wife wrecked that so I bought a cherry 2001 Yukon XL with 200 thousand miles. None rattled or used oil or have...

    The Unexplainable, Unresolved issue an expert LS builder and Dealership can't figure out

    Coolant leaking into the exhaust after you shut off the engine, when you restart it you smell the Coolant as it gets pushed through the exhaust until it burns off; probably drivers side head issue.

    Advanced auto parts battery replacement true story

    Guys who work at auto parts stores are are not competent mechanics, nothing was damaged with this error but you should expect to have your vehicle damaged every time you allow incompetent people to work on it.

    Misfire

    I am betting you need a cam and lifter replacement.
