so i had my cps recall done and a few days later my truck wont start. i got towed home. so the next day i turn the truck over for a long time to see if i build oil pressure when cranking and the thing starts. now when i go to start it i have to crank it over for about ten seconds but then she starts with alot of smoke for awhile. but idle evens out and she runs good. if i shut it down and start it again starts like normal.......whats the problem with the inital start????
