I replaced eight fuel injectors and fuel injector rail on my 2006 BMW 750LI and I now have a fault code 29CC/29CD what happened?

Silverado 1500 or 2500 or 3500 or HD? no pickup told
not told the job you are doing>??
remove them all ,or scope them or just what, no job told
no end goal or task told. sorry can guess it.

like most V6/8 now , it is a sandwich.
the service manual covers all,l buy it rent it.?
toss dice and land on 1500
the rail on this engine, fuel rail like all , intake manifold injectors used;. all injector held down by both rails. left and right
now the steps to off them if is the job,
pull the isolator seen photo 1, far below.
1: pull left rail and right rail
Remove and discard the fuel injector retainer clips by installing EN-51097 injector retaining clip installer and spreading both sides of the clip evenly.
Always use NEW fuel injector collars supplied with injector when installing the new injector. If reinstalling the injector, it is not necessary to remove the collars unless the collars are being replaced.
Replace the injector seals as needed. Refer to Fuel Rail and Injectors Cleaning and Inspection.
Note
Inspect the injectors to be sure that they are clean and free of debris prior to installation. Do NOT lubricate the injector seals. Rebuild the fuel injectors whenever the injector has been removed from the fuel injector rail.


now I will past the other page rails off per the manual read to you.
just bank 1, i am to lazy to post both
step 1 rail off bank1.
Note
Inspect the injectors to be sure that they are clean and free of debris prior to installation. Do NOT lubricate the injector seals. Rebuild the fuel injectors whenever the injector has been removed from the fuel injector rail.

1. Remove the fuel pump insulator. Fuel Pump Insulator Replacement
2. Remove the fuel injector intermediate pipe position?1. Fuel Feed Intermediate Pipe Replacement - Position 1
3. Clean the cylinder head pocket around the injectors of any dirt or buildup.
4. Disconnect the electrical wiring harness connectors from the fuel rail.
5. the fuel rail fasteners are retained in the fuel rail by keepers and may be difficult to remove.Remove the fuel rail fasteners?(1) securing the injector rail?(2).
   Install two sets of EN-49248 remover?(3).
6. Install one remover in each of the fuel rail fastener bores.
7. Remove by turning each section of the EN-49248 remover an even amount to pull the fuel rail and injectors out evenly.
8. CAUTION
9. Remove the fuel rail assembly carefully in order to prevent damage to the injector electrical connector terminals and the injector spray tips. Support the fuel rail after the fuel rail is removed in order to avoid damaging the fuel rail components.
10. Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering open pipes and passages.
11. 1. Simultaneously lift both ends of the fuel rail?(2) and remove the fuel rail assembly from the cylinder head.
12. Remove and DISCARD the fuel injector seals.
13. Some vehicles were not originally equipped with fuel injector dust seals. A NEW seal must be installed when the injectors are removed.
    Remove and DISCARD the fuel injector dust seal (1).
14. NOTE
    Note
    Whenever the fuel injectors are removed from the cylinder head or fuel rail, they will need to be rebuilt. Fuel Rail and Injectors Cleaning and Inspection
    If replacing the fuel injection fuel rail, remove the fuel injectors. Fuel Injector Replacement

Installation Procedure, skipped me. the service manual lists 4 tools
per

Special Tools

1. EN-49248 Injector Rail Assembly Remover
2. EN-51105-1 Injector Seal Installer and Sizer
3. EN-49245-3 Fuel Injection Seal Installer Sizer
4. EN-49245-4 Fuel Injection Seal Installer Sizer

this is first. pull the isolator.

this one step is the GET TO ANSWEREd
Injector work 10x more complex and special tools needed x4

It could be bad injector.

cost of having the fault codes read to check for problems

The ECM does a tune up on the engine every 60 seconds and makes adjustments to keep it in tune up to the point that a sensor goes outside of the set parameters for operation
At that point it records a fault code
Plugs will last the life of the engine ( unlike the old points system)
To keep the system in good order , regular services and use a quality injector cleaner every 10 tanks of fuel to keep the injectors operating correctly

run fault codes as there is a problem sensor in the system. volts at the injector is suspect as the voltage will vary with the fuel requirement.

What is the code? have you checked the in fuel tank electric fuel pump to see if it is producing pressure in the fuel supply rail to the fuel injectors?

signal,EWS manipulated

IF YOU ARE GETTING A THROTTLE PEDAL POSITION SENSOR FAULT CODE.THE THROTTLE POSITION SENSOR IS THE WHOLE THROTTLE BODY UNIT IS THE THROTTLE POSITION SENSOR.THE SENSOR NOT IN GAS PEDAL LIKE VOLKSWAGON. VOLKSWAGON HAS THE ACCELERATOR PEDAL POSITION SENSOR.

There is no solution other than to get the correct injectors. The ohm ratings are not even the same. They are close but close is not good enough for fuel injector PCM drivers they must be with in BMW spec. Should these Ford injectors be on the low end of the scale they will run the BMW injector driver circuits hot and fry them.

15-17 ohms BMW
11-19 ohms FORD

Buy the correct ones. did he/or you compare old and new before switching. One must be taller than the other
