Help 911

As I previously posted, I sold my truck. BUT the guy is supposed to come pick it up tonight, and trying to be a good guy, last night I decided to do a fresh oil change for him, and change out the glow plugs due to the fact the truck started a little rough on some cold morning when I didn't plug it in.
SO after installing the drivers bank (side) glow plugs, I decided to start it up and make sure everything was good. NO JOY I pulled a SES light and a 1613 Injector Drive code. Took valve covers off, to find conn off one of the injectors, put it on and everything starts and runs fine last night. Get up this morning to drive the truck to work for the last time, and UT OH, as truck is warming up, SES light comes on, truck starts running rough, pulled codes. I get a 0603 and the 1613. Shut truck off, go inside say a few choice words, and come back to garage. Clear out faults, start truck, and now I am down to a 1613 code, low on power, rough idle, and SES.
So do you guys just think it is something still as simple as one of the clips came off one of the injectors again and just take valve cover back off and check. What if the conn gets any oil on it?? Thanks and I am just trying to do a good thing for this guy and this happens. I appreciate it!

If in fact that Glow plug change is all you did on the drivers side. I would pull the cover bach off and double check everything. Maybe try unplugging and plugging in all injectors again.

When I unclip the conn off the injector, will it bother it if I get oil on the inside of the plug. Do I need to clean off the two pins if I get oil on them before I plug them back in? Thanks

Of course you want the connector as clean as possible. Get yourself some contact cleaner and use it on all contacts when putting her back together.

Got it taken care of. Thanks. I just took it all apart, and cleaned all the connectors with some carb cleaner, reclipped them and everything is good to go. Starts like a champ runs like a beast. Guy came and picked it up last night. Old truck was good to me, and is gone to a new home. Thanks again!
