Need help! 2003 GMC Sierra SLT 2 wheel drive 200,000+ miles Crank but no start. Replaced fuel pump Throttle body Idle position sensor AGR valve Map Sensor. I have fuel and fire. 2 weeks ago I started it, drove it out the drive way, got about half a mile down the road, when it started idling really high, then bogging out, and finally died. I got it started, but it wouldn't go over 5 mph. I got it parked, now it won't start.

2003 GMC Sierra, gone through about three fuel pumps and three wheel bearings in the past 100,000 miles, from 80k to 180k. Compared to buying a new vehicle, these were inexpensive repairs. I can't get rid of the truck, it still looks beautiful to me and it's hard to find a long bed truck anymore. No rust, Rhino liner bed and tonneau cover to boot

[@RADMAN752]

you missed the absolute #1 problem with these trucks up north- brake lines. they sit on top of the frame and snow and salt builds up on them and eats them away real quick. thanks for posting

When they start rusting just replace the brake lines all at once and you wont need to worry about them. It's a bit of work but it's not rocket science and it's not as expensive as you might think compared to replacing a foot or two at a time. I live in NE Ohio and drive an '04 GMC.

[@mrfrank5757]

I had the same problem with my 2005 GMC Sierra. Replacing all brake lines with new stainless steel lines without a lift was worthwhile but tedious. Rusted rocker panels are also a common Non-mechanical problem.

[@shaffer4220]

I had that issue. A shop wanted $2,500 to replace all the lines! I said they were crazy. They said they would have to bend each line. (I actually have experience in that trade in Aerospace). Instead, for $68 I bought Genuine GM OEM lines online and found a shop to replace all lines for $500. I was happy, and yes I could have done the job but had remodeling going on....

[@elmerwilliamson1970]

Have had a 2000 Sierra for over 20 years and 180k miles and had none of these problems. Only part that has failed is the fuel pump at 125k, that’s it! Have meticulously maintained this truck, and it has been the most reliable vehicle I have ever owned.

[@Vehement_poet]

I loved my 2000 GMC Sierra it had 250k and would’ve ran another 100k with proper maintenance if a certain person would’ve paid attention to there stop sign and not T boned my truck:/ But I have a 2005 now and like it.

[@darkh3lmet82]

@@Vehement_poet I have a 2000 gmc sierra still and it has 318k miles on it. Only one of these problems in this video have happened and that's the wheel bearing. Only the passenger side. My dad owned it brand new from 2000 to 2005 and then I bought it from him and have had it ever since. Currently working on completely restoring it rather than buying a new or even a new/used truck with the prices these days. It's mostly still in great shape, but I'm going to customize it and make it like new again as much as I can. Wil eventually do an engine swap, but for now, it runs great other than a slight oil pressure issue. Only big job I've ever had to do on it was replace the transfer case. Transmission is still original. Have had many people randomly ask to buy my truck over the years and I always turn them down. I'll never get rid of her...best damn truck on the planet!

05 gmc sierra, had since new. 2wd. All 4 non 4wd parts mentioned in video lasted 15+ years and over 200k miles. My biggest issues have been the driver side a/c blend door actuator, and the vent valve for the charcoal canister.

I have a 1999 GMC Sierra SLT Z85 that I purchased new in '99. It has around 130,000 miles on it. I have not experienced any of the problems you mentioned but I am going to double check my front wheel bearings. Problems I have had include an ABS light and ABS Control Module that needed to be resoldered, A/C Compressor failure, rear sliding window that was replaced 3 times by the Dealer under warranty and continued to leak until I installed a 3'rd party all metal track window after it was out of warranty, 4x4 selection switch on the dash needed to be resoldered, module that controls AC fan speeds failed and was replaced, needed to clean the mass air flow sensor a couple times, replaced a sensor on the fuel injection system that was causing the truck to run rough, poles on original battery broke and replaced by Dealer under warranty, and finally I just replaced the water pump in June 2021. Southern truck with no rust anywhere. Needs a new headliner, front seat covers and a paint job due to sun fading (last black vehicle I will every buy).

I have a 2001 2WD (not so great during the winter months in Idaho), but it has over 320,000 miles now. My 16 year old drives it now. I also have a 2011, and it has had so many more problems than the ‘01 (had to replace collapsed AFM lifters twice). The ‘01 has its issues with that many miles, but the major components are still going strong. I know it would smoke the 2011 in a quarter mile, both have the 5.3.

[@fastacker2]

I have a 2006 GMC SIerra 4.8 L 4WD Manual shifter on floor. Great truck. I had to resolder my instrument cluster panel board. (It went totally dead one day). works fine now. ALso replaced the idler/belt tensioner and belt. The steering shaft will develop a "clunk" that you hear when going slow speeds like in parking lots. I fixed mine by packing the steering shaft with marine grease. Someone had a video on how they did this. Took only a minute. I went through some high water and afterwards all my tail lights stopped working. It was just the wiring junction block located under the frame right behind the spare tire. Removed the block connector, cleaned the corrosion and dirt from it and reinstalled it. Easy fix. The door speakers had to be replaced as they were "buzzing". Put new shocks on it. That's about it. Super reliable vehicle. I had all the fluids changed 2 years ago. Radiator/transmission/transfer case etc. (I am in the South, so no corrosion issues). I pulled a large boat with mine for years. Use the towing switch on the gear shift. Clean the MAF sensor every so often. Makes a huge difference.

I've got a 2004 Sierra 5.3 SLT. I bought it in 2018 with 145,000km on it. I've put just over 100,000 on it and have done regular oil changes and preventative maintenance myself such as regular oil changes, brakes, drivetrain fluid changes, spark plugs. But I've had to replace the following since I've owned it, Radiator Wheel bearings Power steering pressure hose twice (power steering pump and lines aren't built to stand -30c up in Canada) One of the Catalytic converters (may need to change or remove the other one soon) Transfer case half (upgraded to heavy duty aluminum from magnesium for the rear half of the case due to a solenoid that rubs a hole through the top of the inside over time). The biggest issue was the camshaft replacement. One of the lifters was failing due to a siezed roller and gouged itself and the lobe of the camshaft. So I pretty much had the whole top end redone including all new gaskets for the engine and a new water pump kit, timing kit. So that was a big bullet to bite. It's rusting pretty bad now kn the cab corners and wheels wells being in Canada. But I love the truck and will drive it into the ground

[@Suds.]

My 2004 Sierra 2500HD has had major cab water leaking issues. The main areas were 3rd brake light, rear window seal, rear cab vent, door weather stripping (this was a major leak) and rubber grommet for the parking brake cable thru the floor pan. Also, the oil pan leaked oil. An excellent running truck though.

[@karlhungus545]

Always noticed that my headlight switch doesn't seem to do anything, but didn't care to look into it. I will now order another one, thanks! I bought my 1999 GMC Sierra 2500 6.0 4wd, long-box, extended cab for $2,500 CAD with 287k in 2012. It had the engine swapped, and both front wheel bearings done by the guy I bought it from. It needed a bunch of front end parts, a new passenger window motor/regulator, and the box was in rough shape. I knew all this when I bought it, but I was only using it sparingly when I needed a truck. I just recently replaced the 2 front u-joints and transfer case front seal. I got lucky and a guy loading pine mulch into the back with a loader in 2013 wrecked my box, and their insurance put a pristine box from an '05 on complete with a new paint job for $0! Other than that I've replaced the spark plugs and fuel filter when I was having severe issues with bogging and acceleration. Runs fine now. The rocker panels are rusted both sides (central Canada...snow/salt), but I'm not sure I will bother with them as the truck still only has 297k on it 10 years later.

[@chrisp349]

2004 Sierra 4x4 Crew cab SLT bought with 20k miles in 2006. Replace Water pump 2 times. Replace hot/cold actuator for front vents 2 times think it was the same one. Replaced front axle seals at around 100k miles. From 20k miles to 90k miles I pulled a 6,000 lbs camper about 7 times a year for 8 years. Replaced rear axle seals around 140k miles. Now have 3 exhaust manifold stud bolts broke off. Leak on Drivers side exhaust manifold. So that's the next thing I need to get fixed. gauge I like the truck and plan to see how many miles I can get on it. Use it as a spare vehicle and son drives it quit abit. He had a 700lbs camper in the bed for about 18 months and drove it around 15k miles with the camper and in the wind. I think that may have caused the rear axel seals to leak. Still runs good. And I didn't have to replace the Brakes until 140k miles. I do change fluids and get things fixed as soon as something is not right. So happy over all. It has been my favorite vehicle over the 40 years I have owned 17 different vehicles including wife and son's. So Thanks for the info on these trucks. I recommend them. No perfect vehicle but like this one overall. March 2020 Bought a 2016 Ford F150 Lariat for the aluminum body to avoid rust going forward. Hope the ford 2.7L Eco boost does as well as the GMC 5.3L v8 did.

I bought an 04 brand new. Had it until this past October when another driver ran a stop sign and I collided with him totaling out my truck. I had over 408,000 miles at time of wreck. Mine was a 2wd so that transfer case sensor doesn't apply. Only problem I had in this list was the turn signal multi switch. Keep in mind I already had over 300,000 miles when this failed. Wheel bearings never replaced entire life of truck. Headlight switch never had issue. Fyi this was a 1500 ext cab with 4.8 motor. My biggest issue was the factory built transmission. Only good for 100,000 miles. Had it rebuilt with upgraded parts and got well over 200,000 with no issues. Water pump replaced 3 times total. Alternator replaced 1 time. And my AC hasn't worked for the last several years only cause I never had it fixed. And the cluster gauge had to be replaced once and later I did a solder repair on it myself.

Good to know, WW! I bought a used 2004 1500 SLE with the 5.3l last year. It had 202K on it, I've added another 4K. Have had only a problem with the drivers door outside door handle, had to de-rust and lubricate tailgate release and replace rod clips, and my cluster lights will go out or dim. Corrective action for the cluster is to push on the headlight switch. Suspect a bad connection, possibly corrosion. Other than that, she's a dream. Even drove it from PA to FL and back last summer to tow grandson's car down.

My 2003 GMC Sierra 1500 has been a good truck overall. One nagging problem is the bezels for the door switches. The plastic clips are broken that attach the bezel to the door and the bezel has to be taped in place. My understanding is the bezel must be replaced. There are several variations of the bezel which complicated the situation.

[@Realitygetreal]

I have seen more issues on the 1999 s with the 4 wheel drive switch than then encoder, and A LOT EASIER FIX!, mine personal 99 it has gone out 2 times

[@whit4275]

I had a 1999 Sierra 1500. Put 182,000 miles on it. Only problem I had was the fuel pressure regulator. Shortly after the second fuel pressure regulator went bad, the pump in the fuel tank went bad. That was at 77,000 miles. After that it was nothing but maintenance. I miss that truck!!

[@tomhalton5764]

Have a 2001 Sierra. Have had to replace both front hubs, driver side twice. On the 3rd fuel pump as well. Cannot complain for 190,000 hard miles though

[@joelstanhope7231]

2003 gmc 2500hd had to replace fuel pump twice over the years

[@foxfam6112]

Just bought a 05 siera crew cab. Had driver side light issues, changed the bulb, went out, I would wiggle the connector then would work again. I figured out the outside Blu clip was pinching the connecters and causing a short, I removed the ble clip and have all lights working like the should.

[@-nobody6272]

Not that anyone will ever read this but mine is an 01 with 390,000 miles. My only problem is the abs. Thats it. Still runs great. 5.3 and still gets 19mpg.

[@richardthomas3858]

Feel pump and abs module are my biggest headaches...I also upgraded the spider Injectors

[@willjay921]

What about the infernal ticking lifter?

[@mcrowley8460]

4wd push-button switch, hazard light switch stuck in either position, saggy body mounts that cost a fortune to replace & of course door hinges that have oval holes where you install new bushings, tip; keep some of the old brass bushing, cut a pie shaped piece out of the old one & shim the new bushing by placing a piece of the old one towards the front of cab.

[@jorjesalazar1068]

my dads lucky that we live in the south . my dads 99 silverado ext truck has 240,000 miles and has no rust brake lines are so new you could clean them and still see the aluminum. only thing he has changed that was a major job was gas pump, water pump , intake and valve gaskets , 4 batteries but still has original motor and trans. obviously he has changed oil, tires reguraly. funny thing is he has no dash lights except the check engine which is for one 02 sensor and thats it no rust everything original and still runs great

[@ryanalan6545]

I have an O2 Sensor problem all the time when it gets real cold 🥶 on a 2002 silverado but after it warms up it good 👍

[@joshuaheck]

We got a 2005 at my brother's gmc long bed 🛌 and its apparently having electric power issues not the battery tho I think uts ground wire or sensors that either need replacement or its the fuse box wall or something may have gotten wet underneath the vehicle 🤔 not sure but I love the balance and the way he explained this video ill continue to to listen to you tube clips and he made sence more then the rest of them 😀 😉 thanks brotha anyone have any other ideas of what happened to our truck and why its flickers the lights but doesn't wanna crank and uts a 2005 gmc white long bed 😉

[@Twosevenboy1]

I have a 2001 Sierra and the only issue I'm having is from a dead stop occasionally you get a clank or a slight hiccup when applying gas pressure with a small knock sound also when starting cold there's a tiny bit of piston slap which goes away after about 20 seconds of the engine running

[@kellismith4329]

Catalytic converters are making the noise, tap the with a hammer you’ll hear the noise

[@tristinmccann2101]

With all the information you have on cars, what is the most reliable car, and what are some of the worst? Thank you in advance

[@andrewtee371]

@Pro Plat Corolla for 11 years and running 160k . Oil, air filter, motor mounts so far

[@TheNine6]

Have a 2004 Sierra. 6.0l awesome truck, what a has guzzler though

[@boiserivervolunteers]

A1 please help. I have a 02 gmc yukon xl 1500. Problem is the PRND321. Last weekend I was in the mountains and it started doing this. I shift to nearly and it's in neutral but the N won't light up which when I was in 4L and went to 4H it wouldn't do it because the N wouldn't illuminate. Same happens when putting it in park. It goes to park but doors won't unlock. It's not a constant thing but just comes and goes. Any ideas? Thanks

[@kellismith4329]

Catalytic converters, fuel pump, steering pump, water pump, radiator (without cap or drain), rear park brake nightmares,all door handles inner, outer, tailgate, fuel injector spider, distributor , front wheel bearings (no grease zerks), oil pressure sender, broken wires and poor grounds - truck has never been driven hard and has less that 130000 miles - on the plus side it is a very nice smooth driving truck, very easy on gas and tires Oh ya and the spare tire is in a tomb, by the time you need it, you’ll never get it out of the mess of rusty cables - also stereo has failed twice and speakers

[@thedarkphire33]

My 05 has hit the other common issues. The rockers rotted and replaced, The guage motors go bad, the transmission went, the encoder motor, wheel bearings, brakelines, the window switch module, steering shaft You name it, its probably been replaced.

[@matthewdoenges6634]

2000 sierra 2x4 sle Bad map, drive shaft carrier bearing, front wheel bearing, cd player,fuel level sender, shocks, rear leaf springs, diff lock, parking break pads, door seals, fuel pressure regulator, bought it for $50. Still love my 20 year old GMC.

[@machattack78]

I’m surprised the door handles were not mentioned! Especially passenger side

[@jasonboscia416]

Upper ball joints, Lower ball joints, one complete steering link both toe rods inner and outer pitman arm, idler arm. Power steering pump. Original motor Original transmission, Original rear and front diff. Runs great but the seats are showing the miles.

[@evelynvalladares5012]

I have a 2001 GMC Sierra SLT and have had none of those issues. However, I do have a dashboard that tends to heat up. Can we talk about that?

[@fastacker2]

Needs to have the instrument cluster removed and the PCB board resoldered. I had to do it on my '06 Sierra. I bought the proper soldering station, the right rosen flux, etc. I think just about every Chevy/GMC truck has this problem

[@jonthelamb4549]

Not sure if it’s mentioned but these are basically the same as 99-06 silverados and the speedo tends to stop working

[@brettcarlow5779]

same problem happened to my old blazer was a trouble shooting nightmare, now i’m looking into these if i get one i hope it doesn’t happen again, my gauge on my blazer would randomly stop working and the shift points would be fucked up

[@thefidgetspinner2007]

Father used to own an 06, purred like a kitten

[@powerpunch1545]

And ABS always misses up on them to

[@coltonpenrod660]

Yeah I have to fix the ABS on my 1999 Sierra 1500

[@Bryan-cs5qi]

Same with me, on my 2001 sierra 1500

[@lisawilliams3982]

What does your abs do. Can't seem to fix mine on 05 GMC Sierra.

[@mudbug535]

I have a 06 Sierra with over 260 thousand miles and never had any of these problems . Video epic fail. I wouldn’t trust this mechanic

[@jacmohr]

I’d say the biggest one is the dash stepper motors.

[@vicarod]

Wow...that video was quick. Nothing to see here folks. GMT-800 truck. Bombproof.

[@1AAuto]
