Chevrolet - 2500 :: 1997 - Chugging When Truck Starts
Apr 27, 2014
1997 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.

Mechanics say they don’t know what wrong… I had some transmission work done on my truck – mostly an leak and replacing the harness – and ever since then after it rains or if we have a heavy dew my truck does the following:
Driving from O to 49 miles an hour truck is fine, as soon as I hit 50 the truck starts surging and you can see the tachometer jumping from 2000 RPM to 2500 RPMs. I drive around 17 miles to work where my truck will sit for seven hours. On the way home the truck is fine. I find this to be more of a problem when the truck has sat for a day or two over the weekend without driving it. Sometimes the “check engine” light will come on, sometimes not.
I have taken it to two different places and neither one says they can find anything wrong with the truck. I have driven this truck for over 11 years and know it very well. There is something wrong, but what? 1993 Chevy Silverado 3500 Diesel....

I 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.

I 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.

I have a 1998 Chevy K2500 with a 350 engine. 220,000 miles. It starts fine when cold and drives fine. My problem is when I shut the engine off say to get gas or run into a store. When I return to start the truck it will just crank over as if it is not getting gas. If I pump the gas pedal it will fire up after a bit. It will start to stall if I put it into drive but will recover if I continue to pump the throttle. Once I am under way it drives fine until I make another stop. The check engine light is not on.

I've got a 2008 chev 2500 6.0 liter. This is a intermittent problem. Turn the key "click" nothing happens, try again it starts. Clock sets back to 1200. Chev garage says it's not starter because clock sets back to 1200. Lights will slightly flicker when you step on the brakes. Grounds have been cleaned, battery 1 year old. Ignition switch tumblers working hard. Any guesses. Chev garage cure is run it til it dies.

I have a 1990 chevy K2500 5.7 350 tbi with 255000 miles on the body and engine. transmission replaced at 200000. When I drive long enough for the truck to get hot (i.e., 10 minutes or so) if i put it in reverse to back into a parking space or my driveway, it just shuts off. i have had fuel filter and fuel pump replaced but what could cause this? it will stay on if I don't drive long enough to get hot.

Mt truck will suddenly die while going down the road. I know it has a oil sensor and wont start or run with oil is low,but recently it just dies in the middle of the road or won't start after a drive of a few miles. After sitting for a few minutes it will usually start. This was happening a couple of times a day until this week when we have had ice and snow, we have been in four wheel drive for four days and it hasn't died or failed to start even once. Whats up with that ?

So my 98 f150 xlt 4.6 is having a issue where the truck is jumping from 1500 rpm to about 2500 - 2600 rpm. You know sitting there trying to get up to speed. then all the sudden i look down and its at 1500 rpm. but still not really going anywhere. So i give it a little more throttle or gas and it jumps from 1500 to about 2500. Its been like this for a month but i thought it was crap fuel. What is the cause or maybe a solution?

I started having trouble with the truck only starting in neutral and it was a trick to get it to start even then. I bought a new range sensor, bolted her up (with alignment marks in neutral) and she's still doing the same thing.

I've got this 96 neon. I can drive it to work and almost exactly 10 miles into the trip everyday I notice a subtle chug. Then it gets worst and within a couple of miles it chugs progressively worse until it dies. I pull over to the side of the road for 5-10 minutes. Then I can start it back up and run down the road another 3-5 miles before it happens again. I've changed the computer, coil, cam positioning sensor, O2 sensor, gutted the cat, changed plugs and wires. I'm to the end of my rope with this car. The codes that its throwing are no dice.

I went to walmart and let the engine run for a while and shut it off. It would not start until it cools off. Now that its cool it starts fine. It just started doing it. Come to think of it i did get some gas in it.

I have a 1993 Toyota MR2 Turbo with about 150,000 miles on it. For the past several years on a cold start (it doesn't seem to matter what the outside temperature is, just that the car has sat for a long time, like overnight), if I try to drive away immediately the car will chug. It almost feels like the car is choking or is not firing. It happens mostly on acceleration above 2500 rpm and in 2nd and 3rd gears, getting worse as you go higher in the gears.
After a few minutes the problem goes away and the car will run fine. Also, if I start the car and let it idle for 5-6 minutes it seems like the car will run fine without the chugging.

My diesel suburban dies while driving. It starts right back up. I have changed the fuel filter and checked for water in fuel.

If I don't keep in the throttle immediately after start up it will stall a lot of the time. It doesn't do this every time or if it sits for a while but if I drive it and then stop off at a store or something and then go to start it back up it gives me this problem. I notice it idles about 3-4k RPM's when I stop at a light or something too.

1992 Ford Explorer XLT 4wd 4.0L (California vehicle) runs good for about 15 minutes, then suddenly starts 'chugging,' loses power, and check engine light comes on. After sitting overnight, it will again run good for about 15 minutes, then repeats the problem.
This problem began AFTER smog check test failed (it ran smoothly all the time before) and after, as was recommended to me, I replaced the 02 sensor. (Failure of smog check, it turns out, was more likely because, unknown, a 10" piece of exhaust pipe was missing, so Catalytic Converter was not connected to the tailpipe).
I had a mechanic scope the Explorer but he could not determine a specific failure from the codes, although he suggested possibly it's the missing 'Octane Adjust Shorting Bar,' or maybe the 'crank position sensor' is bad, but he could not give a diagnosis.

I 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.

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).
