Alarm shutting off fuel pump - need help asap!

[Pedenali]

i lost the remote control of my denali 99 about 3 months ago, i used to lock it using the locks manually, but about 2 weeks ago, the factory alarm started going crazy - tuning on and off continuosly. I took it to get an after market alarm installed but they couldn't disabled the factory alarm; now i have 2 alarms. still haven't been able to disable factory one for a week now - i've been disconnecting my battery everywhere i go. today everything got worst, it looks that the factory alarm shutted off my fuel pump and i can't get my yukon to get started. Any ideas before i take it to the dealer?

I had the same problem happen to me time ago......The thing is that you have to find someone that could bypass the security system.......It will literally leave me where i would be at.... Then i had to wait about 30 minutes and it would start again........ Someone that installs alarms should be able to help.... Because thats what it is a alarm security antitheft that disables the fuel........
