I replaced the rubber lines near the injection pump(supply and returnwith some at the local auto parts store and the truck started up only after a few seconds.I thought the problem was fixed.I started and stoped the eninge about three times and was successful in starting it again.I let it sit for about 20 minutes and now it wont start.Do I need to bleed again?

I did take off my fuel heater a month ago but i live in FL.It has been in the 90's on average every frickin day for the past 6months.
