app problems ???
any CEL? could be fuel filter, when was the last time it was changed? |
changed fuel filter the first time in did this 5 days ago.
Have been getting code P0207 # seven fuel injector open or shorted. Would it run normal if the fuel injector was bad? I ran it 3 miles up to 55 mph and ran great. I did fill the fuel filter with c foam right before. ???

are you sure this is not an LLY? they have injector harness problems. typically its #2 and #7.
if yes, then inspect the harness for rubbing through and repair any found. |
LB7 or LLY?
I don't know how to tell the difference, but I'am going to check the wiring harness for sure. Will let you know. Thanks

http://www.counterman.com/Content/Si...0000036294.jpg LB7 is on top, LLY is on bottom also you may want to do the "Ice Pick" trick if it is an LLY |
lly
I do have a lly. what is the ice pick trick?
|
injectors #2 & #7 have connection issues. using an ice pick put a dimple in the connectors to provide a more positive connection

ice pick
figured out the ice pick. hasn't fixed the problem, mech said I need a new harness. going to let him do it for $540.00 includes the diag he did. I heard that the harness is $250.00.
Mech has a good reputation will give him a try, tired of not having my truck. thanks all |
sounds good.
FYI - most of the "rub throughs" are at the altanator where the harness rubs on a sharp bracket corner. did you check there? |
wiring at alternator
There is new tape and wire cover over this area don't know if there was a previous problem or just preventive maintenance, will check in the morning. thanks

loses power
The injector wire plugs on #2 or #7 did have a poor connection. I closed the gap on the female plugs with a safety pin. I did both and it fixed the problem, I have been driving for 4 days without any problems. Thanks for all the info on my lly. If I have any othe problems this site is were I will go for answers. Thanks a lot.
