2000 f150 5.4 4x4 7700
driving down the road yesterday and i noticed that my instrument cluster went dead and my edge evolution also shut off. the odo read - - - - - - - - and all the gauges read as if the truck was off(there were two lights that turned on, dont remember what they were). the truck still drove fine so i turned off and found a place to park. so i turned the truck off and then to the on position(not starting it) and i noticed that my edge would not turn back on unless i unplugged it and then plugged it back in. with the edge not on the truck wouldn't start. so my question is, is this a problem with my edge or am i having truck issues? this has happened once before with the same results.

thanks

 

did you get your truck running to day if not i would look at your battery because mine did the same thing nothing worked not even my air panel your battery is probably the answer all you do is put it on the charger or get a new battery i would try charging it first

 

Sounds like the battery is fading.

 

the battery is fairly new(within a year) and i have had no other electrical problems. the truck starts and runs fine. even when the gauges and edge went dead the truck still ran like nothing weird was going on. then when trying to start the truck just wont stay running, it turns over and does start but wont stay running for more then a second or 2 and the edge doesn't turn on at all. then when i unplug the edge and plug it back in the truck starts and runs perfect. i know this is out of the norm and appreciate the input

also this has only happened twice now in the span of about 6 months

 

That is weird I still think its your battery because like you said it dies when you have it pluged in but runs fine when its unpluged and it seems your truck doesn't have enough power and goes in to to safefailure mode I would take you truck to the local Ford dealer and have them flash your pcm and then reinstall your programmer but I would look at the battery because that was the problem for me.

 

And another opinion would be have you alternator tested

 

true, didnt really think about the alternator, is there a cheap place to get it tested?

 

If you can charge the battery and get the Edge monitor working, use it to check the voltage output.

 

I would check with your local auto parts store.
They will typically do it for free

 

yea, it works perfectly fine after i unplugged it and plugged it back in, and i'll check that.

 

the battery voltage is fine and it happened again today, this is really getting annoying

 

I would return it to stock when it is working corectly, then see if the problem is still there.

 

yea, i guess i could. so i i return it to stock(level 0) does the programmer still control the computer or will it just monitor it?

also when i set it to level 2 and the trucks in lower rpms(1100-1500) and under some stress it makes a rattling sound(sounds like an octane knock or spark knock). im really just starting to hate this thing

 

That monitor never controls the computer. It has programs in it that you transfer to the computer. You are moving programs back and forth. When you load the 0, you are back to stock.

You just stated something that is a real problem. Something is causing it to run lean. That is a no-no.

 

Are you not getting any codes?
