Why my PSR-22 pump start relay does not start the pump even the automatic sprinkler controller is at manual run mode?

2007 Chevy her ? HHR ? 2.2L 4cylinder , check the run/crank relay ! Relay # 51 in the under hood fuse/relay box.
Power to many of this vehicle?€™s circuits are controlled by the module that is designated the power mode master (PMM). This vehicle?€™s PMM is the body control module (BCM). The PMM controls which power mode (Run, Accessory, Crank, Retained Accessory Power, or Off) is active.
Run/Crank Relay The run/crank relay control circuit is connected to a constant ground and is switched by the ignition 1 circuit or the body control module (BCM). The BCM, will in lieu of the ignition switch position, activate the Run/Crank relay during a remote start event. The Run/Crank relay supplies a power signal to the following circuits, when the a Run or Crank power mode is selected:
?€¢
Automatic transmission shift indicator

?€¢
Automatic transmission (A/T)

?€¢
Switched power feeds to the BCM

?€¢
Electronic brake control module (EBCM)

?€¢
Electronic ignition module (spark control)

?€¢
Electronic power steering module (EPS)

?€¢
Fuel injectors

?€¢
Powertrain control module (PCM)

?€¢
Park neutral position (PNP) switch

Turning the dial to run should not send any electrical current anywhere it simply is set to come on at the scheduled time. If your turning the dial to run and attempting to start the valve manually and a click the pump or valve solenoid clicks, the flow control may be closed, the water is off or the valve has failed to open. Try opening the bleeder screw to see if the valve opens this way. If so, try replacing the solenoid if no, replace the valve.

1) Trippers can wear down. Transformer can go bad if model has 24Volt output. Relay can go bad.

2) Add a comment Feb 2013 with model number, and include if this is new timer or older timer that worked before and stopped working.

Question is not clear.
Do you have programming problem with the timer?
Or problem locating sprinkler heads?
Or a sprinkler valve problem?
Add a comment with detailed information.

Sprinkler timer turns ON-and-OFF.
Timer does not advance the sprinkler to next station. The sprinkler valve advances to next station when timer turns OFF.
For example, when timer turns ON, then station 1 starts watering.
Timer turns off, and then sprinkler valve automatically advances to station 2.
Timer turns on again, and station 2 starts watering.

If manual override works, and dial rotates on time each 24-hours, then worn trippers are suspect.

So the mv and c are supplying power to the transformer/relay and out of it, but the pump won't start until the relay is forced.
I'm thinking the relay contacts are oxidized, and need to be cleaned. When they have oxidation, current goes up, and voltage might appear ok. If any start capacitors are in the circuit, they can be faulty, breaking down under a load, while reading ok. I haven't heard of any caps in these systems, but just in case.
The following blog may help you- it's about different controller situations:

Hunter's website has some things to check concerning the controller:

Looks like it could be microprocessor lockup. It's quite a process, but here's what they say is the fix:

Good luck, hope this helps, and thanks for using FixYa.

have the same problem,, but the small button on the bottom of the start relay works to run the pump or if i put the two start 24 vt wires to the timer 24 vt spaces,, but can not get the timer to turn on the pump when it turns on the water, even tried the orbit help center, and they said it was faulty timer, so i replaced it ( another wasted 2 hrs to return the old and hook up the new one) only to find out it too was exactly the same results. Next round,, i look for a diferent brand timer and pump relay switch,,, hope this will solve my problem

I don't know what is your system set up. However, the system set up should be the following;
1. Your 1-1/2HP sprinkler pump must be installed at
a fix location nearest the water source. (Complete
with power and plumbing lines.)
2. At the end of the suction line is a vertical check
valve with strainer.
3. The suction pipeline must be connected to the
suction port of the pump.
4. At the discharge port, a flow control valve tee must
be installed. The flow control valve tee top is
covered with a plug, which serves as the priming
port when opened.
5. After the flow control valve, connect a short nipple
so that you can put a gate valve to stop the water
flow or allow the water to flow. You may connect
a pressure tank at this point or you may connect
the pressure hose going to the sprinkler.
6. To prime the pump, open the plug at the flow
control top. Fill it full with water, replace the
priming port plug.
7. Turn the flow control valve to full closed position.
8. From full close position, switch the power on.
9. The pump now run on and off due the pressure
switch setting. Slowly open the flow control valve
such that the water pressure remains steady.
10. Take note of the pressure.
11. Shut the power off, and connect the sprinkler
pump hose.
12. Put the power back on, and allow the pump to
run with the sprinkler.

Under this set up, you can run the sprinklers when your pump is running. Hope this will solve problem.

The light sensor to control the automatic headlamps is located on the dashboard. This sensor is suppose to activate running and headlamps. I would suspect the problem is a relay to operate the headlamps if the car uses a seperate relay in the automatic mode. I'm assuming the headlamps work in manual on/off. FYI... The auto mode does not control the fog lamps.
