It started with my gauges bouncing all over going on and off , then it felt like the brakes were on and I had to give it alot of gas to get going.now the dash will work when I turn the key on but as soon as it starts it goes out with the exception of the oil pressure and the charging gauge. The transmission isnt working right at all and I dont dare drive it anywhere. The fuse box under the hood does not test right, only about half of it has power and I am at a loss there! There has been electrical probnlems with it ever since I bought it.

Fuel sensor problem that's been going on with a lot of 2000 chevy blazer also trail blazers and also the distributor there is no seal under the distributor cap cause it to have moisture and cause it not to run and you have to replace it this is to the company or whoever's in charge now the fuel system itself is called a spider sense or what I call it not to run it all the time they must be some type of filter besides the one on side of the vehicle itself because they go out within a year or maybe two years or so this must be addressed so hopefully I get some information to help fix the vehicle that I don't think you I hope I could get some information about it because the fule sensor is a big deal wen they last for about a year and then to buy one for about 400 dollars and then pay another 1000 dollars for labor I think that the injection for the fule sensor should be addressed hopefully have a re call thank you for taking the time to read this and hope you can help god bless

My customer complained of a transmission failure involving, but not limited to a dtc p0785. I asked my customer if the involved vehicle (2000 chevrolet blazer) had any dealer or after market accessories installed, customer adamantly replied: no, "bone stock gm." my customer was not aware that the involved vehicle had a theft deterrent system, manufactured by "karr" and distributed by audiovox with installers nationwide. I have been actively involved with gm dealerships for over forty years and possess a wealth of experience in parts and service experience. I removed the suspect security system and repaired the damaged wiring which resulted in the improper installation. In the past week I have been confronted with four customer complaints which resulted from security systems, aftermarket radios and including aftermarket headlamps. These aftermarket components are the direct cause of system failures involving engine management systems, lights, and numerous electrical failures. I sincerely request immediate and thorough investigation which I remain confident will result in massive recalls of these inferior products.

Ever since I own this vehicle, the ignition switch does not lock. Therefore it is possible to leave the truck and not know the ignition switch is still in the on position. Also, the gas gauge bounces all over the place and I have to use the trip to know when I need gas. This has also been a problem since I own the truck. Occasionally, the low fuel light comes on (I know I have fuel) and the truck starts acting like it's low on gas.

Fortunately, I had just gotten off the freeway and was looking for an address at a slow speed. All of a sudden the car lurched; I had no steering; I lost all electrical control; the car ground to a halt; smoke came out from under the hood. I and a friend got out of the car. Fortuitously, fire trucks appeared. It turned out they were returning from another incident as I could not believe the immediacy of their response. They took over preventing further aggravation of this situation. The battery was boiling. All the electrical wire harnesses were melted. The upper suspension control arm was broken. The firemen's observation was, if I had been going any faster, the car could have flipped. After being towed to a nearby mechanic, I learned the upper control arm had broken. It impailed the starter which shorted. That melted the wiring harnesses to and from the battery, as well as being the cause of the battery boiling. The key issue is that general motors would build a vehicle where the upper control arm is so flimsy it would break. I have read other incidents of the same thing with the chevrolet blazer where, for example, a person was going 30mph, the car flipped, and the person was knocked unconscious. A repeated corporate failure of this nature should have consequences.
