Default MERLIN 160 Question

Hello, I recently purchased my First Merlin, a propane start 160, from another member, it was recently upgraded to a MK2 and has 58mins on it. I just finished the install in my Jet and have a problem. I set the radio function up, and got a green LED on the Fadec ECU. I then went to purge the fuel system, put the pump in manual, it came on ramped up, then stalled and gave an overload alarm. The reason is because the fuel valve Is not opening. I went into the test function, and manually tried the fuel valve, NOTHING, will not click, Neither will the Gas valve. I tried rotating the connectors in the ECU, still nothing, I then took a 4.8v battery and manually tested the valves directly, they click and work. I took my voltage tester and plugged it into the valve pins on the ECU and tried testing the valves again using the GSU. STILL NOTHING no voltage on the voltage checker, for some reason the ECU will not send power to either of the valves, is there something I am missing? The valves only have a red and black wire, the ECU plugs have 3 a -+- Manual says polarity is not a problem. I tried plugging the valves in every way possible, still nothing. Any Help will definitely be appreciated.
