apex cold start

[rtx moose]

Was out on my apex for the second time since purchasing(2007 rtx) and left outside for the first time in the cold last night and it did not start..brought it back into the warm garage and started 2 hrs later..anybody have a clue why this would happen!!!!

Check your relays down by your left foot. Some of them could allow water inside and freeze up. There was an updated one that that had solid state internals instead of the mechanical internals. The new one is very easily identifiable as its RED.
I can't remember which one it should be, I'm sure someone can chime in and clarify.
It's the fuel pump relay.
Here is the part number for the new RED ones: 8GN-81950-00

just replace them all. only 3. i had this happen on my apex at a ''beverage dispersal'' place and luckily it started after holding my hand on it. not all of the apexes have the relays in the same order. find the thread on the relays its all there. believe the fuel has the red wire to it.

If your Y pipes are cracked, the sled has difficulty starting in the cold. Will
straighten out when it warms up, if you can get it to run.

I could hear my fuel pump cycle when it wasn't starting,but it is definitely was from something not liking the cold!!!

Battery have enough juice? it will crank but not fire if its low! cold will do it to a battery ,just something to look at .

I looked up in my shop manual and identified each relay down at the left foot well then took a sharpie marker and labeled each one for future use /need . Again you will have to ID each one by wire color not the order in witch they are installed from factory. The fuel relay will "click" when working so its easy to find and get marked. I have a 07 rtx and have never had a problem yet but carry exra relays and fuses of all sizes in front nose storage bag.

How much gas is in the sled? Mine had this problem last winter. It was low fuel in my case as the pump was cycling but it would not build enough pressure to fire the injectors.
