it is best to inspect these items. You may have a check valve that has gone bad, in your fuel pump, which is very common on your vehicle. So, start by looking at your tune-up stuff and then go from there. Does your truck take 2-3 tries all the time or only in the morning?
until this week it would go 2 to 3 days on first crank but this week it has been 3 tries every time
