Customer Question

2003 pontiac grand prix 3800 gt
no security light ever flashes or comes on
no power to fuel pump and relay wont cycle
when I jump relay i have pressure and still no start
i put in a new ignition (not tumbler)switch 30 miles ago then the car just died on the highway
I think it has something to do with the pass lock system but not sure with no security light flashing. I plan on doing a 30 min relearn in the am but what else can I look at to tell if it is a pass lock problem iam good with wire diagrams and a volt meeter

I also noted that when I turn the key on I have not other lights in the dash and the day time running light module makes a rapid noise like it is low on voltage. I think I am having trouble with the ignition switch i replaced. can I get a diagram of that?
