Diagnostic trouble code (DTC) P0601 stands for "Internal Control Module Memory Checksum Error." It is triggered when the powertrain control module (PCM) detects an internal problem, typically a failed Memory checksum test. The PCM's memory checksum test is performed regularly.Oct 27, 2023
disconnect ur positive battery cable. make sure not to set alarm with remote. let set for about 5 minutes, this happened to my 2003 gmc yukon xl and it actually worked
The little black box under the hood, near the wiper motor box is the chip board that controls them...wack it...sometimes it's just a broken weld and the connection to the wiper motor control doesn't work.
If fuse was bad it would not start at all, definitely not the fuse, running for a while usually means that something gets hot, and thermal switch kills it.
Before replacing anything you people need to go to school and learn how to test .

The EGR valve is located in the engine compartment (underneath the hood). Most engines require exhaust gas recirculation to meet emissions standards.

Did you disconnect the battery when you did the fuel pump?
Did you reset the alarm and engine immobilizer?
Did you check for Diagnostic Trouble Codes?
Factory pedal and sensor do not get just a sensor at a parts store - around $450 dealer installed and they reset the computer trust me I went down your road this was the only fix.
I would recommend finding a shop that has a tool called "Chassis Ears". It is a tool that has about six microphones that are clamped to suspect parts. Once the tech mounts the microphones, he verifies the customers concern by taking the vehicle on a test drive at the described speed. He will switch between each microphone until the sound that is being described is found. This is the best way to diagnose noise and vibration issues. Wheel bearings do not make noise at one particular speed. Wheel bearing noise typically follows vehicle speed.
Something has likely fallen between the top of the liftgate and the cab. It will be the space above the seal. Use a clothes hanger or something similar to remove the obstruction.
