i was told to check the pcm but i don't know where it is located

i have looked everywhere in the car for a release button for the trunk

if so is it part of the overall air filter system

I have a 2000 mercury sable that has been sitting without being cranked for almost 4 years. I am now in need of a car and would like to know what has to be replaced/repaired, other than the battery, for me to be able to drive it again. If anyone has an idea to the minimum to max repairs it may need, I would appreciate the information. I am trying to decide if it is worth the money to repair or if i should use the money to buy another car. Thank u for any information!

pulled brother out of ditch. went down road, engine reved up and seems to have gone in neutral and stuck there. wont move now. If a transfer case on a 4 wheel drive gets stuck, what do I do ?

How do i change the rotors and brake pads on the front and rear

Easy driver. Uneven tire wear

Some fluid started to leak excessivley from my transmission but my fluid level is fine on the dipstick. I was driving then i started to see smoke coming from below my hood. I checked below the car and saw some fluid pouring out.

The shocks i bought seem to be to long to fit, ive raised the vehicle by the frame until the wheel is off the ground but they are still to long ,the parts store insists they are the right ones,is ther some kind of trick to instaiiing them/or do i need to get a certian compressed lenght size shock?

Getting a yellow spark, not the blue hot spark. Checked the spark at the cap and it is weak. G and NE coils are within resistance specs and the gaps are in Spec, closer to 0.008".

It also freezing up won't go up or down sometimes

Can anything "BAD" happen to the engine components or the engine it self?

i was told to replace the freeze plugs but have no idea where they are and which ones to start with. i have refilled radiator a few times since i noticed this problem.

Lost power while driving and car shut off; it has strong crank but will not start. Changed fuel and air filter, spark plugs are new..getting spark from block. Tested fuel injectors..working. Fuel pump relay tested ok. Hear fuel pump working as well as getting plenty of gas. Timing belt and alternator were replaced a few months ago. Battery new. I tried removing gas cap and fuel pump relay and car did start for several seconds before dying...what should I look for next? Thank you.
