Do you have access to IKnow? The code comes up with a description of FRP unable to build during engine cranking
The link wont work when I click on it so thats about all I know dont have any max 7's so someone else might know more.

All in Diagnostic Manual EGES-350
2335
FRP unable to build during engine cranking
FRP below 20 MPa (2900 psi) during engine crank
Low fuel supply
FVCV circuit fault or failed valve
FPCV circuit fault or failed valve
High-pressure fuel pump failure
Pin-point FRP System Fault
At KOEO, verify FRP sensor is within specification. See "Performance Specifications" section of this manual.
Check for Intermittent circuit faults. Open Continuous Monitor session and wiggle the engine harness while monitoring signals for spikes.
Check fuel system for faults. See Fuel System in the "Performance Diagnostics" section of this manual.
Run KOEO Output State Test to verify FPCV and FVCV are working without an electrical fault. See FPCV and FVCV sub-sections in this section of the manual to test these valves.
Check the FRP system for leaks. See "Hard Start and No Start Diagnostics" section in this manual.
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\Purpose
To check high-pressure fuel pump and injectors for inability to reach required fuel rail pressure
Tools
Breakout Box
Fuel Rail Block-Off Plugs
1. Remove high-pressure pump left tube assembly at high-pressure pump and block off pump port. Use Fuel Rail Block-Off Plugs.
2. Using breakout tee, apply 12 volts to Pin 87 of the ECM power relay and ground Pin E-22 and E-61 through the breakout box.
NOTE: Voltage should only be applied for a short time.
3. Crank engine for 15 to 20 seconds.
If engine does not start, reconnect the left side injectors. Remove high-pressure pump right tube assembly at high-pressure pump and block off pump port.
Disconnect the 15-pin connector on the right side.
4. Using breakout tee, apply 12 volts to Pin 87 of the ECM power relay and ground Pin E-22 and E-61 through the breakout box.
NOTE: Voltage should only be applied for a short time.
5. Crank engine for 15 to 20 seconds.
If engine starts, reconnect the 15-pin connector and cap off each injector on the right side to isolate a failed injector.
If engine starts with left bank blocked off, reconnect the left side and cap off each injector on the left side to isolate a failed injector.
If engine does not start after each side has been blocked off individually, cap off all 8 injectors and do Test 10 - Fuel Rail Pressure Check.
Possible Causes
Failed high-pressure fuel pump
Failed injector
High pressure leak
Low fuel supply fuel pressure

| Thanks for all the good info, but we don't have the manual, where can we get it, and we don't have the tools to do the test, it's not in the budget and they still want us to fix it. well thanks again for the good info mr.schoolbus |
