I have a 99 GMC Sierra. 5.3,Auto. I have an compustart remote start system and keyless entry. Remote start and remote entry works fine however sporadically the factory security system turns itself on and will not allow the truck to start. turns over put no fuel pump(I assume since it acts like no gas). After I attempt to start it, the security light flashes 5 times and then nothing in the message center. After several attempts at cycling the ignition, it will restart and all is good for a while. I did scan for codes and no codes came up. I've tried locking everything up and unlocking with the key instead of the remote but doesn't seem to help. Anyone else have this issue before? Any ideas on how to fix this so I don't get stranded somewhere with a truck that won't start? Thanks in Advance.
