That noise is most likely the valve lifters, some noise is normal on these GM engines, if it is really noisy that is a problem. Do you use the correct grade of oil and change at least every 6,000 miles.

Since you have no power to the ignition switch( you can't get the key out). Look to the main fuses first. You can see them threw the top. If the solder joint isn't shiny, pull them first. Since it did start and run, it isn't the ignition switch. Wiring most likely in place. Fuse panel could be bad. I've replaced a lot of them. But not with out diagnostics.

There could be many problems in this situation. Here is a list of some things to check:

1.) Check the wire connection in the door jamb where the wires transfer from the vehicle to the door. Sometimes these connections get a little off and things start acting goofy because the door being open and closed all the time(nothings perfectly designed).

2.) Check the relays in the fuse box, I can't remember if on this model vehicle if they used separate relays for each door or just one for all of them, but the relay could be bad.

3.) Check the locking mechanism inside the door by taking off the door panel and using a multi-meter and a 9 volt battery. I've checked the locking mechanism inside doors with a 9 volt battery before to make sure the mechanism was able to do it's job without being hooked up to the vehicle's power source

Don't know about your car specifically, but most cars with electric fuel pumps are equipped with a oil pressure switch which cuts power to the fuel pump when oil pressure drops. The idea is that in a wreck when engine dies, pump should not run in case lines are cut which could dump fuel on ground and create fire hazard. Switch usually located with normal oil pressure sender.

Hi Keven, I'm Al the owner of Big As Auto Repair

Keven, that flip down cover can be a bear to flip up some times especially if its been on there a long time. Take a screw driver and lay something across the battery to use as a ramp and take the screw driver and using the ramp pry upward on the very end of the cap and it should pop up. NOTE: Be careful though because some of those covers actually unlock from the other end. Hope this helps and if you need further assistance go to my website. Have an awesome day Keven! Auto Repair

Try using a Drain cleaner first, then go for the big guns, such as a drain snake.
