Clifford Remote Start cranks only for a second

Hello everyone, new here. Joined up to figure out this problem I have on a newly acquired nissan Titan.   Im pretty good with electrical so im up to the challenge. The problem I have is with a Clifford 7752X, Everything works on it, except the Remote Start, When I push the start button, the lights come on, and it cranks for a second, then stops 30-40seconds later it will crank for a second again, then stops. Obviously this isnt long enough to start the truck. Now heres where the funny part comes in, If I put the key in the ignition, turn it to ON, then turn it to off and pull the key out, push the remote start, it fires right up. What gives? Also a video of it in action https://youtu.be/PO-hJrHqJ2U

Failed OEM immobiliser by-pass. You also need to test the R/S outputs, You need I believe 2 start and 2 ignition wires, check to see that they are all powered up during R/S. Also obviously check voltage from all fuses to your grounding point.

OEM immobiliser, I havent had a chance to check wires as of yet..working late lately. However heres a good question, would using the OEM secuirty remote cause a problem with this? I bought the truck from a dealer that got it as a trade in, when I asked about the remote start they threw their hands in the air.. I assume it worked for the original owner, maybe the dealer used the Oem remote messing it up?

Unlikely.
