P018b code problem occurs same time as p069e code - how to fix & will this make the car stall or quit?

OBD code P069E is pointing towards the fuel pump control module CIRCUIT. check all connections

Suspect a faulty fuel pump control module or wiring to it. This module is located back by the tank usually near the spare tire area. It is prone to corrosion

P0191 is injector pressure sensor system performance. Nothing on the other code with the letter mixed in. I would erase it and see if it comes back.

If you haven't done it already you might have them run it for codes to see if it is showing any. Autozone does it for free too.

The overdrive solenoid in the transmission locks the torque converter, and at low speeds, if it activates or hasn't released from a high enough speed, it will cause stalling. If that is what's happening, it could be the solenoid, or the signal line to it from the ECM, or the ECM itself not working properly.

P1391(M) Intermittent Loss of CMP or CKP Loss of the Cam Position Sensor or Crank Position sensor has occurredi know that you may not want to take this to a good mechanic, but it may be something simple, or it could be bad.

It's either the fuel pump or the fuel pressure control module.
I have the same condition on an 08 suburban 1500.
I am going to replace both. The fuel pressure control module needs to be reprogrammed at the dealer after install from what I have read.
I'll let you know the outcome.

the test is, off-on, off-on, off-on. See if you have any codes present. end of test is 5-5. which engine do you have? report back any codes.

Unfortunatley recalls are only put on vehicles when safety is concerned.

The stalling may be corrected by something as simple as cleaning out the throttle body. Electronic throttles are very sensative and need to be cleaned out every 20k miles.

The "service engine soon" light could be contributing or could be the cause for the stalling. You will need to find out what the code is.

What timing components are going out? Usually timing components dont "start to go out". So please clarify.

Condensation on the dipstick is normal. How is the water in the oil being determined?

Taking your vehicle to the dealer for service will keep you informed of what is going on with your vehicle. They will let you know of maintenance items, problems they have inspected, and potential problems that may occur.

u followed the pin point tests for these codes you had? did you disconnect the battery after you installed new parts? sounds like u have not fixed the problem, you do have a repair manual correct? did you check the intake air hose for cracks on the bottom which will cause a stall? did you clean the idle speed control valve and the throttle valve, they can also cause this stall, never adjust the the hard stop screw, it will chnage nothing and cause all kinds of other problems, it is not the problem, most likely the intake is sludged up clean it and then disconnect battery for 5 minuter, driv about 50 miles and problem should clear up, if it doesn't you have other issues, recheck for codes.
