engine wont turn over. i was checking the fuses cause the driver door controls for window stopped working. then went on to start the car and the dash lights up but don't display the fuel amount and the trunk button and gas door button also stopped working.


You need to start somewhere.
Take a test light and place on solenoid wire at starter. Have someone turn ignition to start. If test light lights, you need a starter. If not, you need to look farther.
You will find a harness of numerous wires leading to starter. Pull on each one. If one feels rubbery, you have a burned out fusible link. Fusible link comes in a roll and can be purchased at an auto parts store.
The next thing you will have to do if no power is going to starter solenoid is check the electrical ignition switch (not the lock/key cylinder). You need to see f you have power at the electrical switch when ignition lock put in start position.

As for your driver's door wiring, that should be a separate issue, and could possibly be broken wiring at the door boot (pinch point where wires run from door to pillar and inside vehicle. The window is protected with a circuit breaker while the switches are protected with a fuse (2 different circuits). Make sure you find all the fuse boxes as listed in the owners manual.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
