I did the key bypass with the resisters...seemed to work for a while but now when I go out and get in the car it will only start about 50% of the time.

I let it set with the key on for a while to reset the security system and it starts.

What do I need to do to get it to start all the time??

 

may be in the bcm, are there any other weird things goin on? massey may have a couple ideas on this one. havent seen him around here lately. may be workin hard or could be on vacation.

 

Everything else seems fine.....I was thinking that there is another part to the security system besides the resister key in the Vats that can also go bad??

 

you could do a trick we did, ill have to find out specificlly but we have original key lock wired to the computer and have a new one without a chip in the coloum and it starts every time but this was with a 92
