Subject: remote start: crank no start
Date Posted: March 02, 2009 at 8:20 PM

Hey all newbie here to the forum hopefully you guys can help.

i have a 04 silverado im installing a Omega/Excalibur alarm/remote start.

everything works except the remote start will crank but not start.

the engine fires up then shuts down within a half second. any ideas?

all voltage coming from the alarm module stays at battery voltage while trying to remote start.

this only happens during remote start, vehicle starts normaly with key.

thanks for your help - EFIcamaro

have you used any bypasses for the factory immobiliser, and have you connected tach signal and programmed, although my bets are on no bypass.

how do i find those bypass modules?

and i have power door locks, therefore i need to purchase a module...
Power Lock use 457G or 456G module ?

yes you will. Best/easiest way to test. Put key in ignition, do NOT turn the key on, remote start truck. If it stays running(which it most likely will), you will need a bypass. Also, make sure you power up that white wire as 2nd ignition that's in t&t's post

i'm from the carribean and not to sure where you would locate these parts where you live,, dunno if there's a circuit city where you live, you could access it there i think, maybe someone else can chime in to help out there.

putting the key in the ignition won't work for this vehicle, your immobiliser type is passlock 2 so therefore, inserting the key into the cylinder makes no difference, you'll need the bypass to simulate what the key does while cranking, read the following explanation given by and i quote his words "a superbly brilliant contributor to this site" chris wallace 187.

2. GM Passlock I/II type:

Passlock uses a resistor, like Passkey; however the resistor is located inside the ignition key cylinder, and the resistor code is sent once the key cylinder is turned to the crank position. Despite having an immobilizer, Passlock ignition keys are no different from conventional ignition keys. Passlock was introduced on the '95 Chevy Cavalier/Pontiac Sunfire and used on many GM models through 2007.
Bypassing specific immobilizer systems:

Passkey I/II, Passlock II -

Almost every security manufacturer who makes a bypass will have one available for these systems. They are quite common and are connected close to the remote start connections.

Passlock I('95-'99 Cavalier/Sunfire, '96-'98 Grand Am/Olds Achieva/Buick Skylark), and special late model Passlock('03-'07 Saturn Ion, '04-'07 Chevy Colorado/GMC Canyon/Isuzu I-series, '05 only Chevy Cobalt) -

These cars also have bypasses available for them; however some bypasses which are designed for Passlock II will not work, so it's important to ensure that the bypass used says that it's compatible with these cars.

you're most welcome. and remember to verify all wires with a meter.

That's correct. I had "transponder on the brain" while I was reading it. Does the steel key have a black head or is the whole thing steel?

Posted By: eficamaro
Date Posted: March 02, 2009 at 10:23 PM

whole thing is steel

Date Posted: March 03, 2009 at 5:41 PM

Well that's interesting. I thought all of the passlock keys had black heads on them.

Wow...I guess I've posted something useful at some point lol.

t&t tech is spot on as far as the key insertion.

Passlock keys made by GM all have the plastic head; however (at least on Cavaliers/Sunfires) that can sometimes wear off. The plastic is just cosmetic in any case, and it's not uncommon to have an aftermarket key made for a Passlock-equipped vehicle which will be plain steel. Unlike transponders or VATS keys, it doesn't have any special electrical properties which act as a theft deterrent.

The only way to test an install on a Passlock vehicle (similar to putting the transponder key in ignition) is to start it with the key and do a remote take-over. Granted this doesn't confirm that your Start wire connection is good, but it's the best you can do.
