ford focus 2003 door locks problems

When instaling a remote starter on the Focus 2003, door locks are not working after a few minutes. After starting with the remote starter seems they are working. I tried to pulse the BLACK/ white from the door or the BLACK/ blue from the switch, nothing happend. I pulse the ignition with the unlock and work, but sometimes the second times and the gas pump make noise + if the wipers are on....

Thanks
