I always get a sense of satisfaction when I can do things for myself. :thumbsup:
I was able to do my first injector swap today pulling out my stock AD's/AE and replacing them with some of Unlimited's Stage 1.5's A-codes. Many, many thanks to all the threads on here about other people's installs as I was able to do the whole job, from running truck to running truck, in 5 hours which I hear is about right for a rookie installer. A few notes...
I pulled the far back two injectors and let them sit for a good ten minutes before pulling the rest of the injectors as has been suggested here. When I got my 60cc syringe and tubing out I was able to pull over 350cc's of oil/fuel out of EACH of those cylinders. I had no idea it would be that much fluid. The other six cylinders had less than 20cc's in each of them.
After completely evacuating all the cylinders I installed the injectors and did a couple of series of turning the key on and just letting the fuel pump run. After doing this two times I could hear the pump start to build pressure so I moved on to a few series of cranking the engine with the 42 pin connector undone. Crank for 20 seconds then let it sit for 10 minutes, repeat three times. Connected the 42-pin connector, cranked 10 seconds at most, and it fired right up. No smoking, bucking, jerking, weird idle, nothing. Just went straight to a nice smooth idle. After reading some starting issues some guys have had I was very surprised it started this easy. I figured the FRx (RiffRaff diesel) I have on there would get the fuel flowing pretty quickly but evidently the oil started flowing pretty easily too. Good stuff. :thumbsup:
I have only put 50 miles on it so far so I haven't really had a chance to test out Matt's tuning yet but I will get a good feeling for it after this weekend. I will be towing ~6k over ~300 miles so we'll see how it does. Looking forward to it!
I have an OBS idle now!
All for now, I still have to clean up the shop. Just had to share...
