2WSS-AS with 4 button remote

this is my first Compustar remote start install

i have installed many simpler remote starters before but this one is giving me trouble

i have just hooked up the main 8 wires to the appropriate ones off the ignition switch and the parking light wire

anytime i turn the key to ign it blows the 20a ign fuse under the hood of the truck, if i remove both of the relays from the compustar wiring harness it doesnt do this and allows the truck to start.

i figure if i can figure this part out i can finish the rest of the alarm install, but not getting past this step is blowing my mind.

it happens with either of the relays in i should mention, i have tried them both independantly

thanks in advance for any help

I know a thing or two about remote starter. I may be able to help you. I don't remember 8 wire, I recall 5, 6 only if you include parking light, 7 if you run 2nd Accessory with the addition of an external relay. Post your connection from your remote start unit in details with wire colour, polarity, against the connection of the vehicle. I think that is probably the best way for everyone here to trouble shoot your work. At this point I don't quite understand what relay and wire you are referring to. I think detail is the key here.

i have the red wire hooked to the constant power into the ignition switch +12v full time

i have the GREEN / WHITE wire hooked hooked into the light blue parking light wire

i have the red w/white wire hooked to constant power +12v fulltime

i have the white wire hooked to the brown wire(accessory)

this is where i get iffy

the purple wire hooks into the starter kill relay,..which i have the yellow wire hooked to the starter side of the yellow wire,..the yellow and black wire is hooked to the key side of the yellow wire

the green wire hooked to the pink +12v in run position wire

and i have a solid ground on the black wire

i have the DEI 556L passlock bypass hooked up and working now, i have the remote initialized,...the whole system kicks on (lighs, dinger, fuel pump) but then it doesnt crank over,..

when i manually start it after i engage the remote starter i can pull the keys out and it runs until i shut it off with the remote

the second relay seems to be switched for a 2nd ignition wire,...but if i go by the wiring diagram and ground the purple wire it is constantly +12v

my main problem now is getting the starter to engage with the remote start,..then i can weed out the other problems

thanks again in advance for any help

Everything you have seems correct. I believe there may be a bypass issue, bypass not programed, connected or activating correctly during the remote start period. Black Status wire? Where is that connected?

the black status wire is connected to the status input of the DEI 556L bypass

the bypass goes through all of its learning steps and confirms it has learned the resistance,..

i am not getting any power to the yellos starter wires while using the remote start,...but i do when using the key

do i need the factory disarm wire hooked up? if so can anyone give me an idea on where the keyless entry module is located?

What about Tach learning process? Done?

i couldnt find the tach wire so i flipped the dip switches to alternator sensing and hooked that wire up

now i went out after taking a break and double checked every wire,.. all are hooked up according to the manual so i gave it another try

i hit the remote start button on the fob and it did the same thing,...but after about 10 minutes the truck started and died after about 5 seconds,....anyone have any ideas?

what would cause the compustar controller to wait that long to start the truck?

ok i finally got the tach learning to work by hooking up the engine sense wire to the white wire behind the instrument panel

but still after pressing the start button on the key fob it takes 5 minutes for the engine to finally crank and start then dies after about 5 seconds...

i am still confused by the forums as some say that i have passlock 1 and some say i have passlock II the vehicle is a 2000 GMC Sierra 2500 with the 6.0l V8 4WD QuadCab Loaded with all the options except onstar.

i currently have the 556L bypass wired for the passlock I and it learns the resistance code by the flashes of the led

the compustar controller seems to think its working, as it doesnt flash the lights or siren at me to indicate an error, but still takes 5 minutes to power the yellow starter wire.

after surfing through more forums it appears my truck is a passlock II vehicle,. so i rewired my 556L bypass to the passlock II specs and did the 10 minute timeout no start reset, and now the vehicle will not even crank over by the key,...

does this mean it is a passlock I truck?

and if so i am still stuck on why it wont start immediately after the fuel pump kicks off

when i hooked up my bypass 556L ,..

i used the ORANGE / black wire as the group to the 556L ,..then cut the yellow wire and hooked that up to the 556L yellow to key side and BLACK / YELLOW to body side...

the passlock tutorial says that the orange and black wire is the central data wire,...should i be using that as ground?

orange black is the passlock ground, your truck has passlock II guaranteed.

To confirm the above post it's Passlock II.

NOT passlock I.

If you get lock out. Turn the key to ignition and let it sit for 30 minutes. It will reset itself.

I will thrid that motion that you have Passlock II.

ok since i have passlock II confirmed by 3 people,...i went out to the garage and verified the wires on my 556L

on 556L     on truck

black       ORANGE / black
pink        pink
blue        black (on compustar unit (status output(-)))
red        red
yellow      key side of yellow wire
blk/yllw    BCM side of yellow wire

i turned the ignition on for 30 minutes as suggested to clear the no start condition

now my truck wont start with the key, the red light on the 556L stays on and of course will not with the compustar as before,...i cant learn the resistance code because the truck wont start,..

im getting terribly frustrated at this point that i am making no headway any more help you guys have will be greatly appreciated

I would suggest removing the bypass ie wire your yellow passlock wire back together. Personaly my goal would be to get the truck running with the key and then move to remote start. I realize you have the 556L already but I would consider trying trying something less invasive as in cutting wires for the tie. The gmbp, pljx are very good choices.

-------------

i understand now that the gmbp is the better way to go,...but from what i have been reading the 556L is widely used and my application seems correct,..i am wondering if i have done something wrong in the install.

i do not want to tear what i have done out and take it to an electronics shop but that may be the result soon...

i am just confused as to when i have the remote start start the truck without the bypass in it takes 5 minutes to engage the starter,...and why my 556L wont work on passlockII hookups

now forgoing the bypass,...shouldnt the compustar at least try to crank the engine over if i have all of the main wires for the remote start hooked up correctly? and not wait 5 minutes? i could understand my bypass being bad,...but shouldnt it at least power up the yellow starter wire right after the fuel pump is done pumping? i have the tach learning done,..and the ignition wires all hooked up correctly according to multiple posts,..unless theres some input in the compustar that needs to be triggered for it to start

"shouldnt the compustar at least try to crank the engine over if i have all of the main wires for the remote start hooked up correctly?"

Wrong! Passlock II think's someone is hot wiring the car, in your case remote starting with the incorrect resistence everything locks up fuel pump, starter etc...

Now, connect all your passlock wire back. Turn the key to Ignition with out starting the vehicle wait another 35 minutes. Don't go further until you get the vehicle started with the key. Fustrating, remember most of us here do this to pay bills, so we can relate to your pains.

BTW, do you have 2nd ignition hook up correctly? Make sure you get that hook up.

When you say to hook up my passlock wire...you mean remover the bypass from the yellow wire,..then connect the 2 halves back together? if so then turn the ignition on for 35 minutes without starting,...then try to start the truck?

and i dont mean frustrated with the forums,...i mean with the truck as i havent worked on newer gm just older chryslers.

2nd ignition,...ill have to double check that when i get home from work,..but i am pretty sure i have that on the wire the manual calls for,..and it recieves +12v when ignition is on

And this is why DIY RS in bad. No 2nd IGN hooked up, org acc not hooked up (brown instead), no idea how passlock works, etc....... Light blue for Park light???????? Did he even test the wires prior to hooking them up?

And something is hooked up wrong if he is blowing fuses every time he tries to RS.

my relays were hooked up wrong and that was blowing the fuses,...i fixed that,...

my 2nd ignition wire in the truck (white) is hooked up to the relay that came prewired on the compustar,..the one that the manual says is for 2nd ign/acc

i re hooked up the passlock II wire and the starter wire(yellow) that i had the starter bypass relay installed in and now the truck starts and dies,...

i am letting it sit with the key turned to run for 35 minutes to reset the passlock.

is this the correct procedure?

For the 2nd IGN relay, make sure that you use the GREEN wire from the CN2( I think ) harness to trigger this relay. Also, to reset Passlock II you have to have the ignition turn in the ON position for 10 minutes and the light will stop flashing. ONce it stops you can turn the vehicle OFF and then start the truck.
