My brother's truck is a 1997 , 5.7 L gas engine, fuel injected. 100k+ miles.
New plugs, wires, new rotor, coolant temp sensor & air filter & recent battery.
Started a few times after the new air filter & some dry gas & fuel injector cleaner & that was the last time it started.
Turns over but will not run! He needs this truck to tow a trailer to R/C boat shows (he makes parts for R/C racing boats).
I have a 97 Tahoe that I love! The problem is that, every once in awhile, it simply won't start. Won't start, won't crank, won't do anything. I turn the key and nothing happens, similar to having the truck in gear and trying to start it. The REALLY frustrating thing is, when I take it to the mechanic, they can never recreate the problem. This last time, the mechanic had it for a couple of weeks, couldn't ever get it to not start. I had it for a week, and it stranded me an hour and a half from home.
View 4 RepliesI have a 1997 chevy cavalier, 69000 miles. It runs great BUT, when it gets below 35degrees, it will turn over and over but not stay running. After many attempts, maybe for an hour, it will stay running. Regular maintenance, and cold weather maintenance have been applied. New battery and cables. I took it to the shop and they could not find anything wrong.

This morning it won't start. It cranks and the battery is strong but no bang. It was cold. Just below freezing for the first time this year. No blown fuses where would you start?
I have a 2003 f150 4X4. Whenever I go around a round about slowly, the truck sort of grind under the frame and shakes a little bit like I am in 4 wheel drive.
View 2 RepliesI have recently spent many hours into my 97 two door Tahoe. The truck is in Mint shape, and I'm having an acceleration problem. See, it drives fine under normal driving conditions. Say I want to pass somebody on the highway, and I need to accelerate. Well, the truck will rev up, but does not increase in speed. I thought it may be a transmission problem, so I brought it to a transmission place. They said it wasn't the transmission and it may be an exhaust problem.
I brought it to an exhaust place, and they said it wasn't the catalytic converter either. Possibly it may be the fuel filter. Could it be a faulty fuel pump ? Even though it's only a few months old.
I have a 2003 Ford F150 with a 5.4V8 Triton 4X4. The truck is about to roll over 200K here soon. I am feeling/hearing a vibration/grinding sound coming from the truck when I am moving slowly and making turns, either left or right turns. Seems to happen more so on left hand turns. I have changed all power train fluids and filter, and still does it. I do not feel or notice the vibration/grinding when I am going straight or at highway speeds. It is only when I am moving from a stop and making turns. How to diagnose, find out, repair, fix this issue?
View 4 RepliesI have a 1997 Chevrolet Z71 4x4 truck. 350 engine.
This morning I went to start the vehicle and it cranks fine but doesn't turn over. It cranks at a normal speed and then every second or so struggles, and then cranks normally again. About 2 weeks ago I went to start it and the starter didnt engage, it just spun. I released, tried again and it started right up. It did that twice over about two weeks. I figured the starter had gotten too weak, so I replaced.... No change.
The truck has been running quite rough for a little while, and I was doing research to replace the valves and sensors that were recommended (EGR and Idle Air Valves), but the truck seems to have decided that I will do this maintenance now, whatever it is. By running rough, I mean, when it idles, it shakes some. Going down the highway, it runs fine and doesn't miss or anything like that. It is sluggish, but it is a 16 yr old truck with 230000 miles, so it just seemed somewhat normal.
I have checked for spark, and verified that. I can smell fuel when I crank, so I don't think its a fuel problem, although tomorrow I will see if it will fire off starter fluid to verify. I have had the rotor go out before, but it seems when it did that it didn't stagger when I crank.
I have a 99 Chevy Tahoe that the transmission keeps going out in. I've replaced the torque converter, cooler lines, computer. I've even added an additional cooler on the truck and it keeps burning three the transmissions.
View 3 RepliesI have a 97 2500 454 it dies like you trun the key off, but there is still power to turn the engine over but the truck wont start, and after a couple of tries it will start. It might go for a week and not do it or it might go a couple of miles.
View 4 Replies1997 Chevy C2500 silverado... Ok, so when i go to turn my truck on she'll sit there and chug as it starts. usually a few seconds and then roars up just fine. However I've noticed a couple of distinct things. 1. when it does start i see a second or three of black exhaust come from the tail pipe. 2. if its been started recently. IE within 24 hrs it has problems. but if i leave it over a weekend then the first start has no problems. 3. Last weekend we replaced the Fuel filter and the first few starts there was significantly less problems starting but after 5 starts its back to doing it again.
I checked and the fuel pump does work, I've tried changing the fuel filter ( #2 above), and put sea foam into the gas tank hoping to clean out any gunk in the lines somewhere. It does turn on and when it does it runs great so i know its not having electrical problems as well as the alternator is charging like normal.
Im about to take it in for an oil change and see if that does anything, and I'm praying its not a clog in the Catylitic converter.
I have a 2001 Chevy Tahoe. My ABS/Brake lights have been on for awhile now...they go off intermittently, but I think my ABS module is bad. This is a very expensive part.
View 2 RepliesMy wife has a 2004 Chevrolet Tahoe with abut 100K. She did something and doesn't know what but now the car beeps anytime you put it in reverse. No big deal, it's just annoying. I've checked the book and can't find out to disable. How to disable this on a tahoe or know what to look for in the owner's manual.

View 8 Replies98 Tahoe ac giving me warm air once again. 5 weeks ago had it in the garage. they found a leaking schrader valve and re-charged and added dye. checked it and didn't see anymore leaks. they said keep an eye on it and if it stops cooling bring it back. well.........it's going back! it's blowing warm air even though I hear the compressor kick on. what else could be giving me problems? of course i'll take it back but i'm just wondering if a switch failed this time or what the heck is happening. I was surprised to hear the compressor running with warm air.
View 14 RepliesI have a 2004 Chevrolet Tahoe 2WD with the 5.3L V8. Tahoe has 134K. At about 125K miles, I replaced air filter with a K&N, new OEM spark plugs and spark plug wires. The Tahoe has been running great and was getting normal mpg until recently. 15mpg in town and 17mpg on the road is what I normally get. The last 3 fill ups my mpg has been below 13.5mpg. Car still runs great but at 13mpg it's starting to hurt a little financially. Weather here in NC has been normal, my driving conditions or habits have not changed, etc. What could be causing my mpg to drop by so much while the suv still rides smooth and straight?
View 4 RepliesI have a 97 3/4 ton Chevy truck with 136K miles on it. The problem I have is that the truck is slow to crank when it is warm but when the engine is cool like in the morning or when it has cooled after 2hrs or so the engine turns over fine. I put a new battery in it last summer. I was just wandering could it be my starter.
View 8 RepliesMy 2002 Tahoe cranks over fine (new battery), but, will not start. I have checked the fuel pump relay and have control power to energize the relay, but. no switched power from ECM to change relay state. Jumped rely 30/87 and pump runs. No DTC's. Gauge on instrument panel reads no fuel. Scanner shows 56% level. Tried to use my Snapon MT2500 to switch relay state and received error message "generic device control limit exceeded" ECM?
View 3 RepliesMy 95 Tahoe smokes bad on startup (coolant) and a little (oil) on accelerating from zero. There is also a large internal coolant leak. I just replaced the intake manifold gasket as it was the easier fix; didn't do anything. Does this mean it is definitely a head gasket? Anything I can do in the meantime until I have time to pull the heads?
View 1 Replies2004 Tahoe that started with no heat in rear. Checked all hoses and they get hot all the way to back. Replaced rear blend door actuator and worked for a little while. Tonight, took a 90 minute trip and it blew ice cold until suddenly it started blowing heat 45 minutes into trip but then went back to cold after about 10 minutes. Actuator is electric not vacuum. Could it be in the controls where you adjust the temp?
View 5 RepliesI have a 98 chevy tahoe and the truck seems to make a strange noise sometimes when applying the brakes. I can feel (sorta) the noise in the brake pedal. Is this something that needs a scan to find out where it's coming from?
