omega mars-22 r/s problem

just installed this in a an 03 f150 with power locks and anti-theft, used dei 556u bypass, here is my problem at first it was sensing two keys when you would try to start it manually,so the guy who sold me the r/s told me to cut thepink ignition wire. I cut the pink wire and then it works fine put truck back together, then if you started remotely it would run for 10 sec. then shut off. so i let it sit for 1/2 hr and then it works fine again , go out an hour later now it won't start remotely and isn't sensing the key in the bypass or the key in the ignition, so i unplug the antenae on the bypass and it remote starts w/ key in the ignition. Then i plug it back in and works 100% correct again. The antenae is tight right on top of the transponder ring and all connections are soldered. Anyone have a clue? sorry so long. Thanx in advanced.

you might try to hot glue the ring in place. also make sure the the bypass box is switched on and off by the r/sgotskidmarks
