Checked starter, scanned check engine code , says loss communication to PCM/ecm, does that mean , main computer is dead,

What to do?

when I push the auto4wd button it goes into that gear and starts pulling again . or I can push the 4wd high and it will go into that gear and start pulling. when I take off in 2wd and I get up to about 30 mph like I said earlier it goes out of gear . it's like I'm in neutral and I have to push auto4wd or 4wd high to get it engaged and start pulling again .really need help on this problem.

Kees when hit brakes cigarette lighterakes it do it also when unplug in phone charger and doors unlock. I've replace mega fuse battery cables clean grounds no help ground wires

Ometer jumps. Stabilizer comes on can hear relay clicking high temp on transmission after just starting it

67,000 miles
Loud roar
Appears to hesitate going when shifted into drive

All at once...lost fuel gauge, temp gauge, transmission gear indicator, and the message center flashing red battery, low fuel. Also, my diagnostic tool is unable to identify/link to the computer. Service light is NOT illuminated. Had an ASE GM mechanic diagnose and said the cluster was bad, sent it out for a complete rebuild. Just put it in and, surprise...no change. Any insight would be very much appreciated, thank you.

lost communication with fuel pump control module-could the fuel pump be bad? I don't wanna replace it if I don't have to.

Vibration occurs at high and low speeds

cant figure oiut why the trailer lights aren't working

AC is blowing hot air. Both low pressure line and high pressure line are hot (ambient temp is 100 deg F). Compressor does not engage. Freon container pressure gauge is showing high pressure (red zone). Is this a compressor issue?

Start but wont

Filters and still nuthin need ideas

The first time when I hit the brakes hard. Then just when I am driving, then my parking brake light goes on and off. I had the engined checked with that machine and they said first thing is the emmissions area needs a part. I am more concerned about the brakes.

my program on my truck was cleared inorder to delete my engine light to cut off. Thanks in advance.

So going up an incline, my truck started shaking and the gas pedal would no longer working in accelerating or moving it for that matter. The distributor cap was changed and that didn't work. The mechanic hit the tank underneath and it turned on but stopped at an incline again. He changed the fuel pump and now it won't even start. What could it be?? I'm so frustrated =(

ran rough and brought it in and got all spark plugs replaced at 80,000klm, 2 months later blew one spark plug, since then my truck has been blowing through oil.. GM tells me that is normal, Im wondering if they are trying to wait till my warrenty is up, in less than a year! Its been on watch where I bring it into GM to check oil 2-3 times before my 3 month oil change, and each time they add oil.. and say That is normal?

Mechanic said should be 50-100 but still not resetting so I can pass inspection.

Truck will not start, it will not even make a sound when you turn the key. Battery is fine it is at 14, but when you turn the key nothing...anyone have any ideas? I drove the truck home and a few hours later got back in and it will not start, this is the first time this has happened.

During installation the lock pin to hold the steering wheel to true center came out and caused the steering wheel to rotate. I am now trying to get the steering wheel back to true center so it is aligned with the front tires and make sure the steering radius is correct. Does anyone know how to accomplish this short of trial and error?

My 08 chevy Silverado wipers washer comes on by itself, the left turn signal blinks rapidly, and the high beams wont come on. is this a short, or a fuse? oh yeah, my 14 month old loves to grab hold of it when we are riding on the farm. could he have broken something?

Is it all inside the tank because I can't find either one and my spot for the relay in the fuse block is empty

truck was also running Pretty ruff before this happened

have replaced actuator,swithes, motor.

Eveerytime I open the driverside door the radio will not go off, I have to go arund to the rightside door to have the radio go off. Also some of the lights on the radio buttons & on one side of the tempeture controll will not light up when truck is running @ night. Please help

will idle if rev high for a while

Can the window be adjusted to make it close tighter?

It does not make the noise when I put it on 4H or 4L only when I am driving on 2wd does the light(4x4) come on and the noise starts. When that happens I stop and put on 4h than back to 2wd, thats when it stops but ill drive for a couple more minutes than it does the same thing again.

weeks. Sometimes I can jiggle the key just right and it will start. Can hear a noise like the solenoid. Leave it alone for a while and usually starts fine maybe next ten or twelve times then same problem occurs.

4x4 LT off road, crew cab, short box. It has what I assume is stock air bag suspension. There's no torque arm (think that's the right word) from the axle to the frame. So my guess is that my pickup isn't holding tight since I have that play allowing the trailer to start to sway easily.
