STAND BY MODE

This might be saying you need to wait 24 hours before it runs:

7. Stand-by/power saving mode: • When the cycle ends, the green "SLEEP" indicator on the control panel lights up and the LED display flashes "93". The system is now in Stand-By mode. After a while, it shuts down and sets itself in a Power Saving mode. The system will automatically turn itself back on in 24 hours, starting its daily cycle of chlorine production. • The "SLEEP" indicator stays on, while the system is in the Power Saving mode. The LED display however, goes blank after 5 minutes. Press any button ( or ) to view the last LED code.

From the manual:

First have your starter tested by a shop or an auto parts store like NAPA, Auto Zone, ect. If its not that move on to ignition problems, I.E. coils, plugs, wires. Since you already changed the fuel pump and filter it shouldn't be a problem with either of them. Unless its a problem within something inline on the fuel system.

Your remote starter is in timer mode. Pressing the lock and unlock buttons simultaneouly activates the timer mode. When you activate the timer mode the vehicle automatically starts every three(3) hours and runs the preset runtime for a maximum of six(6) starts.
You can cancel the timer mode by starting the vehicle with the key. If the timer mode is a problem then apparently you are setting the timer mode everyday.

There are 2 reasons. While transporting if they lifted with won wards to discharge side, chances are there to oil entering. And while switch on it starts pumping the oil.Secondly, chance for gas leak.
It's advisable to remove gas and check for leak. If no leak, flush out the system and replace drier.
Vacuum and do gas charging. Please write if it's helpful.

From what you describe, it sounds as if one of the microprocessor(computer) ICs is defective, or the soldering to it. For more information, please visit my website at audioserviceclinic.com. Thank you.

Code 93 means the system is in Stand By (Operation Finished) mode. It will start the next cycle in 24 hours and run for the number of hours you have set, Codes are: 88 Stand By (Start Up) 00 Zero Operating Hours 01 Min Operating Hour or (1 Hour Remaining) 02 thru 12 Operating Hours remaining 90 Alarm Code (Low Water Flow/No Flow) 91 Low Salt Level 92 High Salt Level 93 Stand By Mode (Operating Process Finished)

When the system reboots, tap the F8 key during this time and you will see the multi-boot menu come up. Scroll to the title “Last Know Good Configuration” and hit the enter key.
