po449 code is on and have checked selonoid and it clicks when checked with a 12 volt battery? please help if possible

Axle is locked in 4HI

When I plugged in the computer and scanned it . It said random miss fire what do I need to do.

Crank position sensor code came up about a month ago. Replaced both cam and crank sensors. Ran great for a month then started having fuel pump related symptoms. Replaced fuel pump with AC Delco pump. Ran for 15 minutes then died and hasnt started since. Receiving knock sensor codes and crank position sensor codes. No spark. Any idea what could be going on or anything to check??

Bleed brakes

Bleed brakes

35 k miles...ran like a champ..then it dont do nothing when i turn key..lights come on dashboard lights up....turn key nothing happens...did use the unlock button on key chain to get inside ...turn key nothing

Going down the road at around 65 mph and 4 times in a row the truck completely lost power and kicked back on doors unlocked and locked radio kept powering off when I hit the brakes or turned on turn signal all lights on dash were on during the stallings engine even shut off but kicked back on and then after that the truck started shifting hard from 1st gear into 2nd.

All the rest of them work fine just the one. After i pulled the fuses the turn signal blinked at normal speed and after driving it a couple times they all flash at a high speed like one of them is out again but the one still never worked.hope you can give me some place to start looking for the problem. Thank you

air and heat is cut off before cutting off truck

After it sparked once i disconnected it. Got the new one in. But now it wont start. It will crankover easily, i can hear the fuel pump kick on. And i checked the fuses. No luck.. any advice?

No symptoms at all no codes or anything we just parked Sunday evening went out Monday morning to and it would not start. After reading several posts on this site we changed cam sensor, then crankshaft sensor (which was the issue by the way but my son did not seat it correctly) so still would not start so we moved down the line and tested the module and coil ended up buying new ones of those as well and still would not start. So I figured I would go backward and look at crankshaft sensor as the common issue on this site is corrected with that. So took it off and plugged it back in and it started right up but man does it run bad! Popping and chugging and we are now getting codes for misfire and crankshaft position sensor. The old one did not have any of the "washers" shims and looks like it was slightly worn but only on one side not like some of the photos and videos with a small chunk rubbed of so we only used one of the shims (there were two in the box) should we remove a shim or add another or take it back and get a new part?

I know the ac control panel will catch fire. My ex has had that happen,same truck except the controls were on steering wheel. I've got a toggle switch and wired it direct so I'd have some air/heat & defroster.

I cannot fully turn off the traction control and stabilitrac on my truck. I have push the button and then pushed it and held it till the dash says they are off but still they are engaged. Is this something i need to take it in for?

code says service 4 wheel drive, no lights on selector switch

REPLACED MY BATTERY. O2 SENSOR HEATER AND EVAP MONITOR SHOW NOT READY. WILL NOT PASS EMISSION TEST FOR STATE INSPECTION.

They want to charge me $133 to do an oil conditioner, never heard of that before. Can I do it ?

I checked everything but fuel pressure

I was wondering if you guys could replace it under the safety recalls

I have changed the ignition switch already

Properly,

this noise occurs at all speeds and ceases when vehicle is at full stop

Checked & changed fuses.moved wires .radio worked then changed wire again & won't stay on when engine running

Wile driving yesterday out of no where my truck made a loude clunk and hard jerk. and it feels like my transmission or differential broke a tooth. I idle speed home and every 100 feet or so it made that sound and Jerked hard like it wanted to lock up. I do all my own work on my truck. Electrical & mechanical but my dumbshit book (Chilton manual) only gets me so far. I got her ass up, shoes off, and on jacks. I noticed wile taking off her shoes I could spin the tires wile she was in park. Drive shaft did not turn only wheels. Can you please tell me what you think the problem is? Need to get to my job I put on hold. Thank you very much for you time and help.

No noises. Running fine. Oil pressure has been low. Engine light wasn't on. Just went dead going down road and will turn over but wont start.

We replaced the battery first then alternator n starter. Still does the same thing. Amp meter on dash don't show more than 13. Alternator is charging. Where are the ground straps located on a 99 silverado 1500 4x4 LT. 5.3 L. I'm stumped. Unstump me please. Thanks

It knocks for about 10 minutes, then stops. During this time I notice the oil pressure gauge just below 40 at start. When the knock finally stops, the oil pressure gauge is just passed 40. I tried flushing the motor, but to no success. It always sounds like the driver side front lifter that starters knocking, 10 minutes after initial start and stops about 10 minutes after that. Any Ideas? Thought about changing oil pump, but not sure If that is necessary nor could I handle the job.

did i fry the computer?

Already checked fuses and switch.

It did it for 1 day and I haven't been able to get it started since no trouble before that
