01 deville dhs python 581xp +start proble

HELLO to everyone!! 

here the issue. my car wont start!!! the alarm remote start system used to work fine then all of a sudden i could turn the key and get nothing if i cycled the door locks a couple of times... the car would start. but if i used the remote the car would NOT start..  my car has been sitting all winter i had i started about 3 weeks ago and everything was fine..  go to start it yesteday NOTHIN tried cycling the doorlocks NOTHIN so i replaced the battery just to be on the safe side, hooked everthing back up NOTHIN the remote start wont start the car the key wont start the car i get the idiot lights and gauges like its going to start but then there is NOTHIN...  i dont know who put the alarm in or anything but i can get to all the brain boxes there are like 3 of them..

my best guess is that it has something to do with the factory alarm starter kill.. wich is a decent place to start but i know nothing about the wiring on this car and or unit.. i just downloanded and printed off the manual for the python alarm.  i need to know a general direction to start in to fix this issue and also is their i way i can BYPASS this whole system completely..  the python alarm is tied into the factory alarm from what i can tell..

i hope i got enough infor for you gurus so you can help me just ask away if you need some more

THANKS SO MUCH!!!!!

First check to see the databus wire is NOT disconnected at the diagnostics connector........  If that isnt it try and...........Put the key in the ignition turn it to run and leave it for for 10-15min  (make sure your battery is STRONG). now you should be able to start car (possibly remotestart)... if it doesnt  remotestart you will need to find out the bypass brand/part# if it is selflearning you will need to "relearn it". hope this helps. 

open up your lower dash and look for the alarm. If you see it, remove power from the unit ot look for the starter kill relay. It could be a bypass issue. Check your dash and look for a SECURITY THEFT light. if its flashing, then its a bypass issue. When you try to start, does it even crank at all? or you get all cluster lights but no crank. If so this is the starter kill for sure.

thanks guys i will be trying these over the next few day as time allow..

when i turn the key i just get the light no crank. i just pulled all the wiresdown for the alarm it appears that there are some whires that are not connected at all i do see a purple wire that is thin that is just hanging there and i cannot see where it goes it has been stripped to connect to something and i dont see it on the diagrams anywhere.. 

stay tuned...... of course if one of yall close to lovely lansing michigan and just wanna come over and fix it for me ill buy all the beer and pizza you  can handle and ill toss a c note or two in on the deal also..

thanks again

none of that stuff worked the modules that i see are a 555g and a 456a i cannot find any information on how to make the 555g learn.. i dont see any other modules in the car..

how do i get this to learn what its supposed to do ?

thanks

555g is the module that bypasses the factory theft system so the car can start.
456a is a door lock module that is done through data.

programming procedure for 555G

1) insert key into ignition, but dont turn it on, just place into cylinder
2) activate remote start. the 555G unit RED LED will turn on.
3) once the car starts, the 555G units RED LED will turn off. this tells you that the bypass code has been programmed properly
4) shut down remote start with the remotes or you can step on the brakes to dissengage remote start
5) activate remote start once more to ensure it has been programmed properly. Remeber to remove the key befor you remote start it again

going to try this and see if it works.

thanks!!!

this didnt work i put the key in and hit the start button.. the red light on the module did not turn on only the dash light and such.. i did discover something the key that I use for my car has a rattle in it like the pill inside is loose.

i tried the above prcedure with my key and the valet key with no avail

from your alarm, look for a blue or blue with white that sats GROUND WHILE RUNNING or STATUS OUTPUT. make sure that is connected to the BLUE WIRE  on the 555G

there is  a blue wire that comes off the secondary connector on the relay...  there is a blue wire that comes off of the 555g and there is a light blue wire that comes off the 456a.. the two wires off of the 555g and 456a are connected together with another wire..(i do not know what these wires are for or what they do.. ) according to the install book the light blue wire is for the door lock unlock. and the one off of the 555g is for data..

if i connect both of those to the blue data wire on the secondary connector in the relay. i still get nothing.  but lights.

I connected the yellow wire that was cut for the starter and disconnected the relay and still nothing.. the heavy gauge wires are all soldered together.

what do i check on next?

no

Ok

this is what i need  wiring schematics for  the 456a and the 555g modules.

and the wiring schematic for the 581xp

i am going to figure this out ! however i need to proper information so i can get these darts to stick to the wall.

thanks
