When I turn the key to start, all power/electrical cuts off. As if the battery disconnects.

Can't find egr on 2002 4.8 v8, is not where the manual shows it to be and I can't locate

The bed brake lights are not working, but all other lights including the center mount brake light are working fine. I checked every fuse in both boxes and all four bulbs and they all appear fine. Since the center mount brake light works when the pedal is pressed it appears that the brake switch is not the issue. Does anyone have any ideas for what else could cause this? Thanks for your help.

check engine light came on code read MAF sensor, before replacing was going to clean it what am i looking for exactly, and best way to clean?

What do I need to do, already replaced iat and mass airflow

Previous owner used mobil 1 5w30 full synthetic and defense brand filter. Is it ok if I switched oil brands? Like quaker state 5w30 full synthetic? Its about $5 cheaper cause I have to buy separate 1qt bottle due to truck taking nearly 6qts

Code came up for fuel pressure regulator, so I replaced that, an autozone recommended changing fuel filter. Connections are pretty rusty, n I do not have flare wrenches. Could I just leave it n have a shop deal with it? I'd hate to twist or strip fittings.

Intermittint start

Just started a sound under driver side val cover

But it is throwing the p0443 code and sometimes the MAF sensor code. It just started randomly while driving down the road 2 days ago.

It will crank over and start. Sometimes for a second sometimes for 30 seconds. After reading it sounds like the system is not building enough pressure. I do not have the smoke system to perform that test. But it is throwing the p0443 code and sometimes the MAF sensor code. It just started randomly while driving down the road 2 days ago.

Occurs after heavy rain while sitting. Seals are intact. Possibly toward the front of cab and along plastic runner on passenger side.

So I bought this truck brand new off the lot never had to have work done to it expect oil change and tires. 98k miles , I was driving to school, got there and shut my truck off forgot to roll up my window went to start the truck and it made weird noises not normal dead battery noises didn't think much of it just dead battery gonna jump it after class and went back after class and it started back up no delay no problem what could this be?

No issues with the engine, just curious. I run Mobil 1 5w 30 that what previous owner used. Can I switch and still have quality oil?

Replaced resistor for blower motor, cause only highest setting worked. It worked fine after that, week later same problem. Now what ?

Service manual says for my model year resistor an relay are assembled together so entire unit gets replaced. How hard to do. What am I looking for? I'd like to buy correct fitting part before tearing everything apart

I am guessing it was turned off before I got the truck. But it may be something else going on. The Lockout protection doesn't work either so it may be something electrical going on.

Manual says that the drivers side lock should unlock if doors are locked and keys are in the switch.

Blower did make noise on settings 1-4 so I assume it was ready to go anyway.

My husband truck has the same problem, but It has not power windows, anti thief device, or any type of power assist. He turn the key and nothing then goes out and plays with the cable on the battery and most of the time it will start. His problem started over the summer and is still happening. He does not wash his truck a lot either. Tried to buy new cables but having trouble finding them. He also has a different kind of set up. His one cable goes into a fuse box then comes out and goes to starter I believe. So if anyone can help with that thanks. His cables have no build up on them either.

replaced the evapo vent solenoid and purge valve. code still comes back

".can't get the cat monitor to set

Engine trys to start but stops. Could the SRS be involved & how do I fix it?

and the dash controls. I have bench tested the old mode actuator and it works in both directions. I have tried to calibrate several times. Could the dash controls still be bad.
