I have a 2002 Silverado. I am having problems with it starting. I turn the key to on, and nothing!! A friend told me how to reset or reprogram the key, turn to on 10 minutes 3 times. This does work, but it might be a day before it starts. I don't have a key with a chip in it, it's a regular key. Looking for info on bypassing the whole system.
View 3 RepliesDriving while in 4x4 HI up a hill the truck started to slip. I stopped, shifted to neutral, and engaged 4x4 Low. I shifted back to drive and started moving up the hill. The engine started to lose power and the "Service Engine Soon" light began to blink. I put the truck in park. As I let it run a little bit, the engine started to shake as if something was very imbalanced. I went to check under the hood, and confirmed that it was shaking quite noticeably. There was no grinding or clattering of any kind though.
I turned the truck off for a bit, and then restarted. There was no light or shaking upon starting up; but as soon as I put it in gear and started driving I could tell it was losing power, the light came back on, and the shaking ensued. This occurred in 2wd, and both 4wd lo and hi. I parked it at a neighbors place and there it sits for now.
I plan to try and get the codes read. My other vehicles can't make it through the snow we have right now, but it is suppose to get warm later today and might melt enough for me to get one out. I also live out in the country, so the nearest auto parts place is about 20 miles. Same with a dealership service shop. I'm hoping I can buy and return a code reader from an auto parts store to assess if this is something I can diagnose myself or not.
It is the 6.0l gas engine with the 4sp automatic transmission. The truck also has about 107,000 miles.
I have a 1983 Chevrolet C10 Silverado that I am slowly restoring. I recently had to change nylon timing gear and chain. It ran ok but now will only crank but not start. I am getting gas to the carb and I tried a couple of shots of starting fluid. It didn't try to start at all. I pulled some of the plug wires and I am getting spark. The plug wires look good. I am starting to get a little stumped.

Driving around town my truck shifts fine, but when i get on the highway for a little while it will start jumping hard from 1st to 2nd, but if i kill the truck and start it back up it will usually shift fine.

View 6 RepliesI have a 2002 chevy s-10 pickup, 4.3 V6 vortec, 4 wheel drive. It has developed a crank-no start when it's wet outside. Snow, rain, even high humidity.
Things already done: cap/rotor/wires/plugs; coil; fuel pump (fuel psi between 45-55). There was an issue with the distributor being chewed up by the cam - cam gear was inspected and is supposed to be in good shape. A used distributor was installed by the local shop. Engine has 200,000 miles. I was told the timing chain is a bit stretched but there is no timing problem.
Good power, smooth idle, no smoke and there is no engine codes generated by the crank-no start problem. I have power to the coil when it's happening, fuel in the system, even have a spark out of each cylinder wire but it still won't start. I think the car is possessed!
I have a 2002 trailblazer that will start fine in the morning and after it sits for an hour or two, but once i start it and run it for over ten minutes and i shut it off when i try to re-start it, it will crank but won't start. the dealer cleaned the throttle body and injectors, check the fuel pump for presure and it was fine,and they got no error codes?????? I've read that in can be the ignition switch??
View 14 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 RepliesI have a 2002 Chevy Malibu that likes to refuse to start every couple of days or so, throughout the day, but never the first start of the day. It's not the fuel pump and it's getting a spark. It happens in all temperatures. Three different mechanics have not figured out what the problem is. From what I've read online, I suspect an issue with the theft deterrent module or something like that it's called.
View 5 RepliesWhen I start my truck after it has been sitting for a while... I.E. Everything is cold. It takes about 2-3 seconds for the alternator to start putting out voltage (the lights are dim, and the voltmeter on the dash registers about 11 volts). My question is: Am I running on borrowed time and should I change out the alternator, or is there another underlying problem I should be looking for? OR... is this normal; I've never seen this before.
2002 s10 p/u 4cyl stick shift ..
. My "piece of junk" (as my husband refers to it) 2002 Chevy Venture broke down on me last year. It felt and sounded like a tire blew. There were no warning signs. It was very sudden. I had it towed to where I was buying it and they told me the motor was blown because I had let it run out of oil. I knew this wasn't the case (letting it run out of oil) and so I brought it home. My husband discovered the oil pump was not working but before I could afford to put one on to see if this fixed it, it was repo-ed as I had lost my job for no transportation. For about a month, the car lot intended to take the vehicle to auction and then sue me for the rest.
I was finally able to work out an arrangement with them where they held the car until I got my student loan money and paid for it. When I got it back, I expected it to start and to be able to try the oil pump. However, now it will only start when you short out the starter, runs for a second and dies. During these brief seconds, we discovered that the oil pump is pumping oil. I have a theory that while they intended to sell the vehicle, they started to fix it. But why will it only start if the starter is shorted out and then not continue to run? Will a new starter solve this? And could the motor completely blow up in a matter of minutes from the oil pump going out?
I've been fighting this almost a month now.2.2L Engine.
The engine turns over, but want start.
We have fuel pressure (55psi) and a spark.
Sprayed ether in the intake -- nothing.
Changed the crankshaft positioning sensor. Put a simple scanner on it, it stated no errors or faults could be found.
Tried another ignition module, checked the PCM fuse and ignition module fuse, both look fine.
Installed an anti-theft system bypass and followed the reset instructions. Didn't fix.
Just for fun we changed the spark plugs as well.
Now, the person I was with who saw the spark (I was inside the car) says the spark looked "weak" to him. Is this possible?
I have a 2002 Chevy Impalah 100k miles that frequently won't start. When I put the key in the ignition, I get lights, radio, and all electrical signs. But no sound from the engine. No matter how many times I try to turn the ignition, I get nothing.
But then when I stop trying and then come back to the car 5 to 10 minutes later, the car will start with no problem. This seems to happen randomly--sometimes first thing in the morning, sometimes after being parked for an hour. I can go for days with no problems and then it will start happening (randomly) again.
I just brought the car back from a dealership--they couldn't reproduce the problem and can't find anything wrong with the car. What systems or parts might be malfunctioning?
The problem started several months ago. At first it would only happen once in a while and would only last about 5 mins. The first time it happened I had it towed to my shop and it ran fine when it got there. Go figure. They told me they couldn't diagnose it if it wasn't acting up while they had it. Makes sense. But it never does it when I'm there for routine maintenance. Now it's doing it for twenty minutes at a crack. It's usually fine around town unless I get stuck in stop and go traffic. When it usually acts up is when I get on the road between work and home.
Every time I stop for gas I have to wait for it to decide it wants to start again. All of this is putting heavy wear on my starter. I changed the oxygen sensor (position no. 01), because that was the only error code that showed up. That didn't fix it. My mechanic says he thinks the next best step might be the cam and/or crank sensor. If not that, then he thinks we should change out the brain. Somebody else said it might be the fuel pump goin out. because I travel too far for work and I can't afford to fix things that probably won't solve the problem.
I have a 98 Silverado with 5.0 liter, 2 wheel drive. When cold it idles at 30 mph plus. When warmed up it runs just fine. This can be very challenging in icy weather. I have changed the temp sensor, cleaned mass air sensor, etc.
View 4 RepliesI have a 2004 Chevy Silverado (4x4 Extended Cab 5.3 L Engine) that only seems to "heat" the interior of the vehicle through the floor and dash vents. Hot air comes out of the vents no matter what I do ( I can direct this flow of hot air to the floor, dash, or both) . Even whe I use the A/C at the coldest selection it does not change the fact that HOT air is coming out of the vents. I am guessing that a door of some sort is "stuck" so that only engine heat is coming into the cab. Not sure if that is possible but just a thought. Whats going on?
View 9 RepliesI am sure some of us have heard and read the no oil pressure situation. i had it happen to me and I replaced the oil pump and pick up tube all new oe gaskets with the replacement. i still have the same problem. No oil pressure and the tick sound.
View 3 RepliesAfter my truck sits overnight it starts immediately and goes to fast idle for a few seconds, then ithe idle starts dropping until it gets to approx. 400 RPM.If I drive off immediately it will correct itself in a short while, otherwise I need to baby the engine speed until it runs on its own - usually five minutes.I cleaned the MAF and performed a MAF tap test with no success.

View 7 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.
2000 Silverado 5.3So I recently replaced my head gaskets. And I think I'm finally done working on this truck when I took it for a long drive and it did a little sputter and then backfired. I thought it was nothing since after the backfire it went right back to running perfect. Then again another day it did it again. Sputter. A loss of power and the BANG backfire and it was back to running like new. At first it was very rare. Maybe once every other day. Now its doing it 2-3 times on a normal drive to work. And it will idle rough during one of these spells as well now. When it starts to sputter and lose power I can throw it in neutral and rev it a few times. Once it backfires it's back to running like new. Only codes I'm getting are o2 sensors but I have no cats. Just straight pipes from headers to a turn down exhaust. I was thinking maybe a fuel regulator but I had replaced that just a few months ago. Could it have already gone bad? I changed my fuel filter not long ago and cleaned injectors and rails when replaced head gasket.
