Without the proper testing equipment an knowledge ( factory service info. ) You have no idea what's up . an don't have a chance of fixing this . Checking for DTC'S - diagnostic trouble codes is always the first step . Take's a professional type scan tool to read these codes. Serial data info from module incharge to PCM/ECM ,enable or disable fuel and or starter operation . Sends coded messages Your best bet , take it to a qualified repair shop . That white component is the ignition switch . The design of the passlock™ system is to prevent the vehicle operation if the proper ignition key is not used in order to start the vehicle. The mechanical key, in normal operation, will turn the passlock™ lock cylinder. The passlock™ sensor will relay the passlock™ data to the body control module (BCM). The BCM will determine the validity of the passlock™ data. The BCM will send a code password to the vehicle/powertrain control module (VCM/PCM). When the VCM/PCM receives the correct code the VCM/PCM allows the fuel injectors to operate normally. The passlock™ system requires the VCM/PCM and the BCM to communicate the various functions in order to operate. These functions transmit over the class 2 serial data line CKT 1807. For an explanation of the class 2 serial data operation refer to Data Link Communications Circuit Description in Wiring Systems

when you open the door there should be a tringle trim cover at the rough place where the mirror joins to the car. once you remove the trim (normally by popping it off or sliding it up or a mixture) there should be 2 or 3 nuts. remove the nuts and the hole wing mirror can be removed from the car. note sometime the connector behind the tringle trim cover or behind the door trim itself. be care when removing the wing mirror not to catch the wires

Some of the older GMC ECM's keep the error code for some time. You may have to have it reset and see if the code comes back. I had a Yukon that had a check engine lite on for about 6 months and it finally went off last week!

It could be the pick up coil in distributor or the spider injection under the intake has broken injector supply lines,for they are plastic

Have the fuel pressure check and make sure it's within specifications....... sounds to me it is too low pressure

Without knowing what car it is ...make. model and year this is a very vague question. A quick and dirty educated guess sounds like your timing has jumped ... if it's a timing belt, open the cover and check the timing marks ... or if it runs put on a timing light and look where the timing is ... sounds like it's firing after top dead center.

New parts can still be bad , check for cracks also check wires for white arc marks on each other or where they might contact a ground source .

I had this problem too. On drivers side under the hood, literally right under where the hood shuts across from master cylinder. There is a small nipple that comes out of the fender way up under the fold in the fender. There is a hose that's supposed to hook to it, look for it.

We all wish there was! Sorry, gotta drop it down.

Is there a question to this post?

seems you have several different problems. High beam working and no low beams=dimmer switch is bad. Reverse lamp not working=bulb socket bad,wiring broke,bad ground at back Brake light on drivers side stuck on=brake light switch

There are a number of sensors and controls that can cause this problem (mainly MAF, TPS, IAC motor, EGR valve, O2 sensor) and you will have to figure out which one (or more) is causing the problem. First check for error codes with an OBDI code checker and follow up on the results.

It sounds like there is no power for the memory go to the parts store get a wire diagram and check the memory fuse and wire

It sounds like a fan blade is bent and is making contact somewhere , these are usually aluminium and easily pushed back into shape , but if the fan has worn out its bearings it will need to be replaced unless there is some sort of material that has wrapped itself around the fan causing it to jam up .
