somtimes it will and somtimes it will not p1684 and e100.6,400.1,100.0----
wife coming home one day,said it just cut off at stop light..but started right back up...next day about a mile from house died and nothing will not turn over...so i come home from work look at it find a blown fuel pump fuse replace and dis-battery...fires right up....50 miles later dies while idling on me....cycle key few times fires up nothing for 100 miles so i give it back....dies at her work .....ughhhhh....long story short its here now when its not going to crank i can tell because oil light isnt on.. when its on it fires up....only had this thing 6 mths bought it because it only had 67,000 and thought it would do good ...any sugg ...thanks guys so much
in advance........laid off right now...need to do what i can...i have alot of tools....

 

am i in the wrong place

 

Did it blow the fuse the second time? And yes you are in the right place, just seems to slow down sometimes here.

 

hasnt blown fuse since.......

 

putting in new batt,and making a better ground for that thing they have on the motor mount,,,,,

 

ok anyone know ecodes got 100.0 400.1 100.6

 

not alot of help on here is it.....

 

try the wiggle test on the wirring to and from the PDC.
also try wiggling the wires from the PCM

those codes arent the best to diagnose. they are instrument cluster codes

400.1 = improper power shutdown
100.6 = 'SBEC/DEC/MCM communication failure'
100.1 = 'loop-back failure'

sounds to me like theres a disconnect from power to the computer, if your not bald you maybe by the time you trace this one.
electrical gremlins like this are one of the most time consuming endeavours.

hope you got a good DVOM and lots of time, let me know if you require wiring diagrams

 

What is a PDC and a DVOM?

 

PDC= Power distrubution Center (its where all the fuses and relays are under the hood

DVOM = Digital Volt Ohm Meter, as electricity is hard to see with naked eye you may need this to trace, measure current.
