I've finally found the cause of my problem. It was the Chevystar, which I always thought was desactivated until my van was blocked by it. I've removed the Chevystar and everything came back to normal.

My truck won't start

Chevrolet Silverado 2007 extended cab 150000 miles
It has been running well. Started up fine this morning. Got to my appointment. Came back out to leave and truck would not turn on. It was as if the battery was dead. When the AAA mechanic checked the battery it was fine. But the dash lights would not come no when the key was turned. Then they did but there was no effert to start. The engine might click but nothing else. The dome lights were bright and working. It was putting out a full voltage the mechanic said. But again the dash lights would not come on. But then they did again.

I have a pulsar LT upgrade trip for my Silverado, and what I discovered when I was taking it to the dealership was I was taking a pulsar LT main chip in disconnecting it but really, I should’ve been disconnecting all the wiring, which is only two harnesses, and then connecting back the originals next to the colder intake so when you take the pulsar LT and disconnect is the main chip it deactivated the whole vehicle. I’m assuming it’s a safety precaution which is a great one Security is key

Flashing engine light

Chevrolet Silverado 2005 2005 v8 5.3l at  207000 miles
Running rough. Feels like fuel filter. Or pump. Are both in my gas tank? Or could this be a sensor?

Multiple Misfire if check engine light flashes. Sounds like either worn spark plugs, plugged injectors. Pull the plugs and change them first and wires first to see if it clears it up. If not run fuel injector cleaner thru it

Running hot

Chevrolet Silverado 2000 1500 truck 5.3 160000 miles
My 2000 1500 Silverado started running when I was hauling something a few weeks ago and would cool down when I would turn it off. Then it started getting no matter what if I was hauling something or not so I changed the water pump, fan clutch, radiator, all new holes, new thermostat

Engine power loss

Chevrolet Silverado 2003  197900 miles
Hi, I've been noticing some engine power loss in my van lately. I've change the air filter, its holder's lid where the sensor is located, I've cleaned the sensor's wet connection and the vehicle keeps failing. I have then disconnected the negative pole for a while and the problem was temporarily solved. After turning the engine on and off, the failure returned and now there is nothing I can do to take it away. Can someone give me any idea or solution? Thanks!

The same occurred to me and the problem was some poor contact in the battery's terminals. Clean them and it should be solved.
Art from United States 9 years ago
In my case it was the TAC module which is close to the hidrovac or brake booster. I recommend you to scan your vehicle and check if any failure is provided by the scanner.

Engine noise

Chevrolet Silverado 2011  90000 miles
My car started making a strange noise, as if it were a template's bearing or damaged band, but we've removed this last one and nothing changed. We've also opened the car's distributor and replaced the oil pump which was softly damaged, but again nothing changed. We've checked it with a stethoscope and the noise seems to be coming from the bottom. There was no overheating nor an oil failure, any help to give me?

The noise might be coming from a piston rod's piece of metal.
adolphus from United States 9 years ago
Thanks for your comment, Delores. I tell you that we've finally solved the problem when we took the engine out and found three damaged propellers. We've then changed them and luckily the car is now working properly.

Fans failure

Chevrolet Silverado 2010  64000 miles
My van's fans are suddenly turned on and the temperature's pressure gauge is disabled. On top of that, a script warns that there is an engine overheating. The thermostat and temperature sensor were replaced, it worked better for two months but the problem is now back. What might it be?

Do you know whether your new temperature sensor is a good quality one? Nowadays there are many of them out there that are cheaper but only last for some weeks, or in the best of the cases months. You should check this first of all.

Air conditioning

Chevrolet Silverado 2005  15000 miles
While driving, suddenly 2 of the ventilations start giving off hot air and the other 2 cold. I then have to stop the car, turn off the engine and wait for 5-10 minutes until I can start it again working properly. It is not that often that this failure takes place but I would like to solve it. Thanks.

My van had this inconvenient and it was a freon gas deficit.

Buddy, the vehicle has got a switcher containing some sensors and 40 amp fuses. Try changing them and checking whether your problem is solved.

Doesn't start when cold

Chevrolet Silverado 2010  85000 miles
As I start my car when cold, the engine is too rough, there are no revolutions and it produces some small explosions. After 5 seconds or so, it suddenly accelerates and then comes back to idle speed. Which electronic feature might be causing this failure?

You should check the pump's pressure when starting the engine. If it is low, that might be what is causing your vehicle's explosions. And talking about accelerating and going back to idle speed, that is absolutely ordinary.

No running lights

Chevrolet Silverado 2016 Chevy Silverado 1500 LT 127000 miles
I recently had an issue with the Battery Distribution Engine Compartment Fuse Block (see pic)
Truck would not start. Zero power. As a quick fix we jumped two of the terminals and that got it started. However, I have no running lights. Everything else works including headlights, brake light and blinkers. Because the Battery Distribution Engine Compartment Fuse Block will not arrive for a few days and I need to drive in the evening, I was hoping a mechanic could tell me if there is a temp fix by maybe jumping the terminals while I wait for the part to arrive. I currently have a 30 Amp inline fuse fuse so the truck will run. Please help
