That's what I would do.

Checked for signal from main box to relay , ignition 1 yes, ignition 2 no signal checked programmed setting to make sure it was set for ignition or acc and it is correct so thinking the main box is problem. Any work around like connect ignition 1& 2 together before relay?

While that may work, your system should have a separate 4-pin remote start auxiliary harness, with a negative ignition output. I'd use that to trigger a relay. You could try jumping that to the small pink/white in the ribbon harness, or just use your own separate relay.
Since the negative outputs are only rated at 200 mA, one relay coil can draw nearly that while the engine is running. If you were to try running a second one with the same output, it could fry.

The "separate 4-pin remote aux harness" that geepherder (who I respect) mentions is on the Relay Satellite, not on the main module. (I can see the 4-pin receptacle in your pic of the satellite, and I remember that's where it was on one of my installs). Here's what I would do / check:
Set up your volt meter to monitor voltage on the large pink/white wire. In a quiet environment, ground the small pink/wht trigger wire to ground by back-probing the terminal with a paperclip jumped to ground. If the Large pink/white powers-up, the trigger in the module is faulty. I would de-pin the small pink/wht from the module, and piggy-back it onto the pink IGN output. Use the IGN trigger for both IGN 1 and IGN 2.
If the above does not power-up the large pink/wht: Set up your volt meter to monitor the small pink wht. Red lead on a +12 Volt source, and the Black lead on the small pink/wht. The meter should read nominal 0-Volts. Remote start the truck. If the meter indicates +12V, the trigger is functioning, it can be concluded that the relay in the satellite is bad. Use the trigger to control an external relay for your IGN 2.
The predecessor to the "Satellite Relay" was a group of 4 regular relays. Two of these were triggered by one output of the module. The relay coils in the large relays are about 125Ma, so the total load exceeded the "200Ma Max", but that's how DEI did it on the 551T which they sold a gillion of. I don't know what the tiny relays in the satellite draw, but I'm sure it is less than 125Ma. I have had a dual-relay install in my DD pick-up for 6 years. I cycle the RS about 15-25 times a week. The module is still fine, so I don't feel the "2 relays on a single output" is harmful.
There's a little more info for you. It may help.
