Does it crank over?
Was it doing anything unusual last time it ran?
Can you check for any codes?
If it won't even crank over, and the batteries are good the first thing I would check is the nsbu.
If it will crank over but not start, I'd check the oil and see if there is fuel in there. If not, I'd replace the fuel filter, prime it and try again.
You should fill out your sig with truck details including any mods.
