1715 won't communicate
Hooked up the 1715 programmer as usual,fuel pump fuse out,key off etc.
Plug in the tuner and it powers up OK.
Go thru the Ignition off,Tune or Diagnose,Fuel Sytem disabled stuff.
Get's to Establishing Communications and then it beeps and says Error!!! Check Connections.
I've checked the connections a hundred times and it still will not work,and I've never had a problem with the connections before.
I just used the tuner several days ago and the only maintanence done in that time was a tire rotation.
Anybody have any ideas???
Am I missing something here???
Need some help Please!!!

Once more I am reminded that I should try to do no more than breathe after working nite shift!!!!
My eyes were not communicating with my brain.
Anyway the reason it was not communicating was I did not switch key to ON when it was plainly telling me to do so.You'd think that after trying this a hundred times I would have noticed this......
Oh well maybe I'd better go lay down.....
:o :o

I just went through the same thing when I tried to install the original programming. I called tech support and finally figured out that when I pulled the fuse for the fuel pump I was shutting down the PCM also. The answer is to pull out the fuel pump relay thus allowing the PCM to operate.

Just a couple comments................
Pulling the fuel pump fuse does not kill power to the EEC-V PCM in any FoMoCo vehicle we've ever flashed. If that were the case, you'd see literally thousands of posts here from people not being able to flash their PCM's according to the documentation included with the 1715 Micro Tuner.
However, what we *have* seen that is when the wrong fuse is removed. The real key here is to make sure to look up exactly which fuse it is for the fuel pump in the vehicle's owners manual. This is because the fuse location diagram that is embossed in the under side of the lid is sometimes wrong in a few F-150's - one of our own F-150's, a 2001 5.4 4WD Lariat (SVB1), had that mistake on it's power distribution box lid, and other customers of ours have reported the same thing. Now not *all* of them or wrong, or even a large percentage of them - we don't know how many actually, but *some* of those diagrams embossed on the bottom of the lid are wrong. I wonder if that might be the case in Jungleman's experience, perhaps?
I can't tell you how many times (literally) that we have flashed these FoMoCo PCM's, or how many tens of thousands of other people who do it exactly as described in the Micro Tuner's documentation, with no problem at all. We *ALWAYS* remove the fuel pump fuse as is instructed in the docs before we'll flash a PCM.
For "Jungleman" - if you wouldn't mind, could you please share with us what type of vehicle you ran into this with, and the exact fuse# and it's amperage rating that you removed, as well where you looked to see which fuse it was supposed to be? Year, make, model, which engine, etc? Anytime someone reports something "different," we like to know as much as possible about the situation so we can potentially let others know if there is something else they need to look for on a particular model, etc. (And thanks in advance for those details Jungleman, if you can still remember them by now, that is!
)
This whole issue of disabling the fuel system is simply to avoid any potential for an admittedly extremely rare scenario - if you happen to have an injector leak theoretically you can have fuel being pumped into a cylinder the entire 6-8 minutes it takes to flash the PCM. If that were to happen, there is potential for a bang when the engine is started, if enough raw fuel is puddled in the cylinder and ignited.
Even Ford dealerships are also supposed to disable the fuel system before flashing the PCM - though in our experience, we don't see this being done with any regularity. In most cases we've actually witnessed at dealership service departments, they usually don't bother as the potential for a problem is so slim overall.
It's just a matter of being thorough, Superchips doesn't want even the potential for such a rare scenario, so they simply follow FoMoCo's recommended guidelines and instruct the user to disable the fuel system before flashing the PCM. If someone wants to get creative, there are any number of ways to do that, but the easiest by far is to simply remove the fuse pump fuse on the EEC-V PCM's in these trucks.
