I love how there are no answers on here I was trying to find out why my key won't open the trunk in general and I'm not sure but I believe the other key may actually open the trunk but it's my girlfriend's car and I don't ever think about using her key to check but I'm going to now as there are no answers here hope you figured it out 4 years ago now LOL

The bolts are "Lefty Loosey"

Make sure the right spark plugs was fitted first

Nah... Robert Hofland, The security key either works or it does not... If the "DEALER" actually has a MECHANIC around... That would a NICE (albeit unlikely). YOUR Dealer ... (In my opinion: needs a little integrity and / or a brain)... Your can get "FREE" reads to get the Diagnostic Trouble Codes (DTCs) pulled out of your On Board Diagnostic System... Don't buy anything... ESPECIALLY not Oxygen sensors... just get the codes READ-OUT... Come back here... We have some pretty good experience...!! >> If it only does this when it is cold... >> or when it has been standing... Point to completely different troubles... but both in your FUEL SUPPLY. Getting those codes is PARAMOUNT. Exhaust shops, parts stores... even some mechanics... If it is something simple... You might be wise just to get it fixed... or diagnosed & fix it yourself... Pretty sure you are BETTER OFF not letting the "dealer" continue at VERY BEST... being incredibly INCOMPETENT... dishonest... (creep... etc. (in my opinion)). Try it... Big savings...

You need to have the security system programmed, many locksmiths can do this, and of course the dealer as well.

You have a leaking head gasket if you are sure it is motor oil.

I believe the voltage regulator is controlled by the ECM ....computor

From what I can tell, the 2 codes aren't related. The BBEVAP error can be as simple as changing the fuel cap (try this first) to a vacuum hose leak or a purge valve malfunction.
As far as the transmission goes, first check your fluid and look at the color; if it's brown or gives off a burning smell, it really needs changing. It's true that the modern flushing system is bad for older transmissions but changing the fluid and filter through the transmission pan will be the only way to truly diagnose how bad the transmission damage is. Leaving old fluid in the transmission will only lead to it quitting on you sooner than replacing the fluid,filter etc. Hope this helps and best of luck!

Ignition immobilizer probably needs to reprogram is the security light on. I am not sure that your car has a fuel switch. If the car has a fuel cut off system, for you to reset it, the manual says to turn the key to the acc setting n let it sit for a few seconds then turn key off then turn car on. Fuel pumps do go on these and from what I remember, pretty easy job if you have some mechanical ability. Press the helpful button and Follow me on Fixya for more tips

Your owners manual will let you know for sure. It should be in the underhood fuse / relay center

A noisey fuel pump can be an indication of a worn pump. You have to do a fuel pressure test to determine if the pump is supplying proper pressure and volume

Starter not engaged. No fuel. No spark.
