2002 3.4 impala turns over but wont replaced fuel pressure regulator and fuel filter checked fuel pressure reads 50 has spark just wont start up any ideas I thought maybe crank sensor but if that was bad it would not have spark. When you turn the key to the on position it comes up red battery light then goes to solid orange or yellow security then back to battery light back and fourth I have read alot about the security system shut down but wouldn't that disable fuel pump that what I have read anyways pump is working has spark and rolls over just wont fire up I read if its the security issue the car wont even turn over. I have it sitting in garage now with key in on position letting it sit like that for 20 minutes or so I read that resets the security problem if that is even what is wrong
thanks for you help thanks
