Check programming for each zone. Be sure each zone has time on it.

SOURCE: I just purchased a Rain

First I would assume that the timer is OK and that there may be a wiring problem in your system that your old timer was responding to as well as your new timer.
Connect zone 1 wire to the timer output for z1.
Connect z2 wire to the timer output for z2.
Connect z3 wire to the timer output for ZONE 4.
And connect z4 wire to the timer output for ZONE 5.
Now see what happens. If z2 runs with z4, it is probably not the clock.
Do you have an electric MASTER VALVE? A valve that opens only when the zones are running.
The fact that the old timer blew a fuse indicates a wiring or solenoid problem more than a timer problem.

Rainbird esp modular controller will not operate system -

Make sure that the transformer is supplying the 26 volts ac required by the pump relay and zone solenoids. If the voltage is there and unit still will not operate then the electronics are to blame.

When on auto mode, the system just keeps repeating the zones.

I don't feel you can repair system by yourself. Excuse me if you can; so do it.
You should take it to an authorized Rain Bird repair service. Look for it on some listing they might have given you when you bought your stuff or contact them from here:

Zone 1 stays on all the time even while other zones go

Sprinklers and valves can get clogged. First turn off your controller, then remove Zone 1's valve... see if you can determine if it is clogged. Then clear the clog or replace the valve.

Esp-6tm controller shows err3 and err4 but one and five zones work. turned valaes on manually and the water comes out of heads. bad control box ?

When you say turned on valves manually, do you mean by operating the bleeders on the individual valves? If so, that has nothing to do with the electrical operation of the valves.
The fact that you are getting err3 & err4 leads me to believe that the wiring that electrically operate these valves are shorted.
Move the wires for valves 3 & 4 to terminals 1 & 2 on the timer and see what happens.
If err1 and err2 come up, the problem is in the wiring to the valves #3 & #4.

I have installed the timer i have 4 wires to go into the 4 zones no wire to go in the master only one zone works??

Do you have ground wires to each station in series? Without the grounds, the other stations will not work. Determine the ground wire at the working station. The power wire will correspond to the color of the wire on the terminal at the controller; the other wire will be the ground. The ground wire should continue to the next station, then next station, and so on.

Sprinkler control box appears fine, but sprinklers to not open

If all zones do not open, I would check the water supply first. Verify that the water is indeed on. If you have water at each valve location, then I would check at the wiring at the controller. Use a Multi-meter & check the resistance (ohms) between the common wire terminal and the wires at the terminal for zones 1 through 6. If you get an open loop (O.L.) reading on all zones, I would think the common wire is cut or disconnected. Also look for a rain sensor that could be wired into the common wire. If it is faulty or stuck, it could cause an O.L. in the wiring. If a rain sensor is wired in at the controller, disconnect it from the common wire path and connect the common wire directly back to the common terminal. If it works now, then you have a bad rain sensor.
A normal reading should be 20 – 60 Ohms from the common terminal to any zone wire. If you are in that range, the only other thing it can be is the output voltage from the controller to the valves. Use a Multi-meter & check the voltage at 24VAC terminals where the external transformer is connected. You should have 24-30VAC. Next, open zone 1 and check the voltage between the common wire terminal and the terminal for zone 1. You should have the same reading as you got for the transformer. If you have nothing or a large difference, then I would suspect the controller might be damaged.
Remove the power & 3 volt lithium battery and wait 2-3 minutes, then reprogram the controller and try again. Good luck!
