What to do if there is no nozzle cycle?
First, check if the wires are connected in the correct order to the solenoid valves. If the replica is firing correctly but the TP NM error appears in the application, it may be because shots were taken without connected pressure. In such a case, you can either ignore the error or clear it by cleaning the DTC.
The engine works correctly from about 60-70 PSI. If there is no full nozzle cycle, you can increase the pressure on the regulator and reduce the nozzle cycle time. If this does not help, you can install a tappet plate spring with a smaller force.
