Help! Replaced #8 injector, Ran great for a day. Now died and won't start.
I am hoping someone might be able to help shed some light on a situation that I am having with my 2005 F250. Yesterday I took off the driver's side valve cover to replace a bad #8 injector. I reassembled the truck and it fired right up after about 20 seconds of cranking. The truck had never ran better. I drove it for about two hours that night to help work all of the air out of the system and to give me peace of mind that the repairs were 100% correct. All was well when I parked the truck last night. I woke up this morning and went out to start the truck and it fired right up and dropped into a really smooth idle. About 20 seconds later the truck started missing really badly and eventually stalled. Now all I can do is crank the truck over and it sound like it's hitting on about 4 cylinders. I have a feeling that the stand pipes may be leaking since they were removed and reinstalled when I removed the HOP lines to get to the injector. I checked the ICP pressure while cranking and it would initially spike to 2000psi and then after 1 second it would settle at 1300-1400 while cranking. Is it possible that I have a stand pipe leak? Would the ICP reading still be that high if either the stand pipe or the dummy plug was leaking? I need to get this thing back on the road ASAP, so any help would be greatly appreciated.
