RECOMMENDATIONS FOR INSTALLATION OF CP3 CONVERSION KITS · Remove and inspect the high-pressure fuel regulator for debris. If debris is found in the high-pressure fuel regulator, we recommend replacing the regulator, the injector return lines, and the check valve assembly.
GM Pressure Regulator: P/N 12611872 GM Injector Return Lines and Regulator: P/N 12639000
· Inspect the sealing washer on the fuel temperature sensor for any damage, defects, or corrosion on the surface of the washer. The sealing washer is not individually replaceable, so the sensor assembly will need to be replaced if damage, defects, or corrosion are present. Inspect the banjo seal on the dosing injector feed line. Replace as necessary.
GM Fuel Temperature Sensor: P/N 12643002 GM Return Hose Banjo Seal P/N: 12630832 GM Dosing Injector Feed Line P/N: 12656313
· Clean and lightly lubricate the low-pressure fuel feed tube compression fitting to ease installation in the valley. We recommend replacing the existing fuel feed pipe since leaks can occur due to deformation or corrosion on the mating surfaces of the compression fitting.

IMPORTANT FUEL SUBSYSTEMS EXPLAINED
Fuel Control Actuator (FCA): The fuel control actuator regulates fuel from the CP3 to the high-pressure fuel rail and is located on the rear-facing side of the CP3. The FCA can also be called REG 1. Incorrect wiring or faulty connections can cause a no start condition. The connector should have a yellow wire and a black wire.
Fuel Pressure Regulator 2: Regulator 2 controls the pressure in the high-pressure fuel rail. It is located on the front of the driver’s side fuel rail. The connector for the regulator should have a purple wire and a yellow wire. Failure of regulator 2 will cause the high-pressure fuel rail to not build adequate pressure for the vehicle to operate or even start.
Fuel Injector Return Regulator: The fuel injector return regulator is a constant pressure regulator and does not have any electrical connections. The return system requires at least 4 bar (58 psi) to be present before the injectors will begin working. If the return system cannot reach 58 psi when starting the engine, the return lines and regulator will need to be replaced. This component will normally be located near the thermostat housing on the engine. Image at right does not show the installed location. GM Injector Return Lines and Regulator: P/N 12639000

SYMPTOM: SURGING UNDER ACCELERATION
Pass 1 Pass 2
Is the vehicle equipped with an aftermarket lift pump?
Measure the fuel feed pressure from the lift pump at the CP3. A fuel feed pressure in the range of 2-3 psi to the CP3 is recommend. If the fuel feed pressure is found to be above 5 psi, reduce the pressure to 2-3 psi and re-evaluate the surging under acceleration.
If yes, proceed to step 2
If yes, proceed to step 3
If no, proceed to step 3
Has the fuel feed pressure to the CP3 been verified to be below 5 psi? Step 3 Was a new injector return line and return regulator (constant pressure
valve) installed during the CP3 conversion kit installation?
Step 4 Is the vehicle operating with any aftermarket tuning?
Pass 5 Pass 6
Contact Fleece Performance for further technical assistance. Verify with your tuning source that the fuel control actuator (FCA) values are equivalent to the OEM stock values or utilize the values provided in the table below.
If yes, proceed to step 4
If yes, proceed to step 6
If no, replace the injector return lines and regulator,
GM P/N 12639000 If no, proceed to step 5
If your values are equivalent to the stock calibration or the table below, inspect the FCA driver in the ECM. A faulty or weak driver can cause the engine to surge. Install a test ECM or replace the ECM if required.

Verify that sufficient fuel is reaching the CP3 and cleared of any air entrapment in the fuel supply lines. Has sufficient fuel pressure to the CP3 been verified? Connect the CP3 fuel feed line to a remote fuel source that bypasses the low-pressure fuel system. Try to start the vehicle. Does the vehicle start? Is the vehicle equipped with an aftermarket lift pump? A fuel feed pressure in the range of 2-3 psi to the CP3 is recommend. Is the lift pump achieving its rated operating pressure?
Repair low pressure lift pump. A fuel feed pressure in the range of 2-3 psi to the CP3 is recommend. Inspect and repair the low-pressure fuel system. The following are potential failure points.

Low pressure fuel lines: Inspect for cracks and/or broken lines.
Fuel filter housing: Inspect for blockage of fuel flow or a cracked housing that allows for air ingress.
Fuel primer bulb: Inspect for cracks allowing air ingress and failure to prime.
Fuel line flange fitting in valley: Inspect for leaks and air ingress into fuel system.

Low pressure feed hose on CP3: Inspect for cracks or leaks allowing air ingress. Are all electrical connections to the CP3 and high-pressure fuel system correct? For the FCA and Regulator 2, refer to page 6 of this document. Verify that the fuel temperature sensor on the cascade block is connected and that all harness connections are properly made. Are all electrical connections correct? Inspect and reconnect wires to their proper locations within the highpressure fuel system. Is the actual fuel rail pressure matching that of the commanded pressure? Rail pressure during cranking should be at least 1500 psi. Rail pressure during should be in the 4500 – 5000 psi range. Is fuel returning rather than making it to the fuel rail?
Pressurize the return fuel system by connecting a test port to the 9th injector and pressurize the system with shop air. If the vehicle starts, replace the injector return lines and regulator (GM P/N 126390000).

Is the high-pressure fuel feed line from the CP3 to the fuel rail free of damage or leaks? Replace the high-pressure fuel feed line and ensure that the polymer isolator has been properly installed. Vibration of the engine will damage the high-pressure line if the isolator has not been installed correctly. Reference the first image on page 5 of this document. Is the fuel rail plug properly seated and is the nut torqued to 22 ft-lbs? A loose or improperly seated rail plug will allow air into the fuel rail and can cause a no-start condition. Has the fuel rail plug torque been verified? Remove the nut, clean, and reseat the rail plug. Torque the nut to 22 ft-lbs.

Does the crank no start persist? Verify with your tuning source that the fuel control actuator (FCA) values are equivalent to the OEM stock values or utilize the values provided in the table on page 7.
If yes, proceed to step 17
If your values are equivalent to the stock calibration or the table below, inspect the FCA driver in the ECM. A faulty or weak driver can cause the engine to surge. Install a test ECM or replace the ECM if required.
