2006 6.0 hard start

[PRSM6.0]

So here's my issue. I have a 2006 250 with a 6.0. This past week I changed my fuel filters. I changed the secondary filter on Wednesday night and Thursday the truck started fine. Thursday night I changed the primary frame mounted filter and installed a new drain plug. Friday morning the truck started fine. Saturday morning after the temp fell to roughly 17 degrees overnight I tried starting it and it turned over, ran for about 2 seconds and quit. I shut off the key and let the pump run and It started hard the 2nd time. Sunday I had the same issue but it took 3 tries to start up. I pulled the filters and made sure all looked fine and didn't see any issues. I thought if I plug it in tonight it may help but now my block heater is tripping my gfi outlet. I need the truck in the morning and don't really know where to start. Any help would be great. Thanks.

You need to cycle the key on, listen for the pump to run (prime)then quit, turn off the key, turn the key back on, wait for the pump to quit, turn the key off. Do this a handful of times to prime the system then you should be good to go.
