code alarm ca420 in 06 equinox

I used to install alot of starts until about 02.my new gf has a single button remote start that does not work anymore. Unit responds to program options,tach learn etc but when hit start button does absolutely nothing.any ideas? Thanks

Check fuses, check outputs for voltage...When all else fails, Read the Instructions

Hood pin switch showing ground all the time?Soldering is fun!

they have never installed hood switch and i tested to make sure wire not reading ground.this model had a toggle switch also that book says needs to see ground to operate so they have that grounded permenent.brain has power,tested ign acc wires. brain clicks and flash lights in program mode,remote learn,tach learn etc but hit start and no flash,click nothing.i even ordered a used brain on ebay andsame  thing???im not real familiar w cars that dont use start wire and couldnt find much info on the sec bypass it has but are there any that need to be reproggramed after loss of power? and if so would start still attempt to start like on older cars? thanks

As long as the R/S's ignition outputs timing is correct ( ACC and IGN come on

simultaneously ) and then ACC drops while the Starter output goes to +12V, theengine should crank.  If the Passlock2 bypass is not working, it should still crank but without fuel pressure it won't start / run.  What type of bypass moduleis installed?

I am not familiar with Code Alarm systems but try turning Diagnostics ON ( Feature 6 )

and see what type of error you are getting on a remote start attempt.

-the bypass is an astroflex 392-061-112-00.the code i get is 8 flashes which is not on the list but yet there are probaly no recorded attempts as i dont even hear relay trigger,no light flash etc when push start but yet when i program remote unit responds to.....that is why im so baffled

Strange problem.  Not familiar with that bypass module, either. 

You probably already tried this but...

Check to see if the thick Pink IGN1 has +12V on it with the car off.  ( It shouldn't )

Pull both fuses ( Red and RED / Violet wires ) and do a continuity check on them

with your DMM.   Re-insert fuses and verify +12V at the Red and RED / Violet wiresat the CA 420 connector.

Verify with your DMM that :

Pin 4 Gray/Black does not show chassis groundPin 7 Gray does not show chassis groundPin 9 Brown does not show +12VPin 10 BROWN / Red does not show +12V

Double check the CA 420 chassis ground connection.  Should be with a soldered terminal ring to a clean, paint free, solid metal frame bolt.

Switch to Tachless mode and try a remote start.
