I need help have a 2000 7.3L. I found fuel in coolant tank. did some research and found out it could be injector cups. found a sweet deal on new cups and o-ring with tools to do the job for under $400. the job went well i think not to hard to do. found 3 of the o-ring shot. on 3 different injector. put truck back together and turn key to let the gp warm up. I SEEN THE FAN MOVE LIKE THE CRANK TURNED but I DIDN'T START THE TRUCK YET. what was that? now i have a long crank . act like its winter. but it 90 outside. the hpop is full see no leaks acts like fuel bleeding off. even if u try to start 30 sec later it still long crank. if u try right after shutting it off and try again starts right back up . any longer then its long cranking . when running runs strong lot better then before the work i did but i dont understand why i have a long crank now. IF ANY ONE CAN HELP IT WOULD BE GREAT
How many miles have you put on it since you did the injector work? There's probably still air in the oil rails. What you need to do is take it out and run the snot out of it for 40-50 miles. That should cure it.
