chevy silverado remote start

i have a 2004 chevy 2500hd automatic and i installed a avital 5303 and i have a omega immobilizer. when i first installed the remote start it would crank up and then die right as it tried to start. then i put the omega immobilizer on and now all it does is crank and crank and crank i have soldered all main connections and tec connections, check connections atleast 5 times a peace. i have went over and over and over this thing for the last 4 days and cannot fig out whats wrong. i have changed it from volatge sence to tak to just crank and no luck still does the same thing it just cranks. but when i unplug the immobilizer it tries to start and then dies right before it starts any ideas on whats wrong ?

and the tak is hooked in the white wire i believe pin A5

ok i all most have got this right i got to messing around to day and unpluged the passlock 2 from the key switch and IT WORKD!!!!!!! but then i plug it back up and the same thing happed that did before. sooo i fig my passlock is not bein disabled why would this happen?

the second accessory is not hooked up could this be causing this?

Dont remember which one...but either the 2nd ignition OR the 2nd accessory MUST be hooked up.  If not it will cause all kinds of problems.....

i have the second ignition hooked up hooking the second accessory up tn im about out of ideas.

Sounds like a bypass problem. 

Which Omega Passlock2 bypass did you use?

Did the bypass module program as per the istructions? 

Did you have to cut the Passlock2 Yellow wire as part of the install? 

Was the truck having starting problems before the install?

Soldering is fun!

i used im01 omega bypass and yes programed per instructions door locks work. and no i hooked it up d2d and the vilot wire to pin a2 on the dignostics port. i also wired up the second accessory this morning.still nothing. 

and the truck stats fine with the key just not with the remote start

Possibly a dumb question, but what firmare do you have flashed on the IM01?  It looks like AMDL v6.00 is the correct and latest version.

When programming the bypass, at Step 3 did you set the module to Type 4 ( 4 blinks ) and start the truck with the key?

Soldering is fun!
