Ошибка P069e?

Обидно, однако... Можно было бы серьёзно упростить задачу.

Пошукал в литературе по P069E:

Examples of vehicles equipped with an FPCM include:
2008-09 Hummer H2
2008-09 Saturn Vue
2008-09 C/K trucks (most engines)
2009 Chevrolet Corvette ZR1 (manual transmission)
With the increase in electronic returnless fuel systems (ERFS), it is important to know that there is a new module associated with ERFS. The new module is called the Fuel Pump Control Module (FPCM) and it is a serviceable GMLAN device. It is a microprocessor that controls the voltage supplied to the fuel pump (located within the fuel tank) to achieve the desired fuel pressure requested by the Engine Control Module (ECM). There is also a new fuel line pressure sensor, which sends a feedback signal to the FPCM, so the FPCM can determine whether the desired pressure is being achieved.

Fuel Pump Control Module DTC P069E

The FPCM stores diagnostic information, and if a fault is detected it will send a message to the Engine Control Module (ECM) to illuminate the malfunction indicator lamp (MIL). When this occurs, DTC P069E will set in the ECM. The specific faults themselves, however, are stored within the FPCM, and must be retrieved using the FPCM menu on the Tech 2 scan tool. Faults may be due to issues with the electrical wiring or connectors in the FPCM circuit; or they may be due to performance issues within the FPCM module itself, the fuel line pressure sensor, the fuel pump MRA, or communications with the ECM. The FPCM also has Special Functions within the Tech 2 for controlling the Fuel Pump Duty Cycle and Fuel Rail Pressure.?
TIP: The FPCM can sometimes be overlooked when diagnosing a problem involving the fuel system. If while using a scan tool (Tech2) a DTC P069E is detected, return to the Powertrain menu and select Fuel Pump Control Module for additional diagnostic information.?
Checking the FPCM for DTCs could lead to more accurate diagnosis of a problem, faster determination of root cause, and shorter vehicle

This information applies to 2009 vehicles equipped with a gasoline engine and Fuel Pump Control Module (FPCM).
On rare occasions, a customer may experience one or all of the following concerns:
1. Intermittent crank no start condition
2. Extended crank
3. Vehicle stall condition
4. One or all of the following codes:
- P069E, P0230 or U0109 set in the PCM
- P0606 set in the Fuel Pump Control Module (FPCM)
These symptoms may be the result of water intrusion ino the Fuel Pump Flow Control Module due to a disruption in the case seal.
Check the Fuel Pump Control Module (FPCM) for fuel control-specific DTCs (if communication is possible) before inspecting connections. Then refer to SI for those fuel control DTCs. If module replacement is required, replace the FPCM by following the Fuel Pump Flow Control Module replacement procedure in SI and using the special procedure below. Also clean or repair the related connector if necessary.
Before installing the new module, please follow instructions below to prevent the vehicle from returning.
1. Clean the backside surface by wiping or brushing to remove all dirt, grease, water, etc. Surface must be clean and dry.
2. Use GM approved RTV sealant p/n 12378521. (Canada p/n: 88901148).
3. Apply sealant to the joint between the aluminum back plate and the plastic housing (fig. 25).

4. Insure that the sealant fills the gap in the joint. Work the sealant into the joint using an index finger. Leave at least a 4mm wide bead on the surface (fig. 26).

TIP: Review the RTV manufacturer's MSDS before use. Wear chemical resistant gloves. Avoid contact of RTV with eyes, skin and clothing. Avoid breathing vapor and mist. Wash thoroughly after handling. Do not wear contact lenses.
5. Allow the sealant to cure at room temperature until it is firm and rubber like. This will usually take a full 24 hours to cure.
6. Install FSCM on vehicle.

Заявляют, что работает. Но для надежности надо техсаппорт пытать.

Как альтернативные варианты -HPTuners и EFILive.

Но, первым делом проверить, что Fuel Pump Control Module загерметизировали.
