Hard start, smoke when runs.

OK guys heres my problem. The '02 F-350 truck I have is giving me fits. P-1316 is the only code I'm getting besides the one that pops up after you disconect the batteries. We went in and checked the inj. harnesses and both were unplugged some what and one of the tabs were broke. So installed two new v/c gsk's. and inj. harnesses and still same problem. Hard to start, and no power. Smokes really bad trying to start and when it finally does fire up it still smokes some, just doesn't ever clear up. Still misses and wont rev. past about 1500rpm. I have a 2000 truck equipped the same way, 7.3, auto, 4:10 L/S rear. I have swapped the PCM, and the IDM between the trucks and nothing changes on the '02. The '00 is parked since theres only two of us no need to use the other truck(batteries dead, tags exp,no ins) so I haven't tried to start the '00 with any of my swapping parts but it ran perfectly when it was parked last spring.

Anyway I'm fixing to check wires from the IDM to the inj. to see if there is a short, I found a thread showing the pin locations and such to verify that all is good with the harness. About all that is left is Injectors themselves. I have a friend that has a snap-on scanner that will do a buzz test but he doesn't no how, can anybody walk me thru it to see if one is bad before I take it to Ford for a raping? We ran a diagnostic test on it and it showed a misfire on #2 and #8. Unless its something the IDM harness looks like I need two injectors. Thanks to all who can help this truck has been down for a week, its costing me money two ways now.

Truck is fixed and running!

Well come to find out one of the harnesses that I bought to replace was DEFECTIVE!
The more I checked things it didn't make sence. I kept coming up with a short(ground). Finally found the harness I put on the driver side was pinching the wires from the back injector(#8) to the glow plug wire of the next cyl.(#6) together and causing the short. They were pinched at the point where they went into the plug and the housing was crimped together. Went back and swapped the harness and put the truck back together for the third time and she runs great. Started right up cleared out the smoke within just a few seconds and ran great. Now things can get back to normal....somewhat!?!
