The blazer sat for about a year before I bought it. Could the vent be plugged

left tailulb burnt out i replaced it but tail light still don't work

will changing fluid and filter be enough or do i have to have entire system flushed

My brake lights don't light up wen I hot the pedal.

wen I press my brake pedal. The thread brake light works but the other two do not.my tail lights work and my Blinker's work but the brake lights do not.

The handle is in the park position,but the screen says neutral and its in neutral.

My 4x4 will not engage the the case is new the actuator is new everything is new almost but the 4x4 buttons only flicker when I start the vehicle then they don't show anything and does not engage into 4x4

Addressing this problem this has been done:
1) fuel system clean out
2) MAF sensor replaced
3) fuel pump and filtering replaced
4) cooling system flush with thermostat replaced

Additionally, after engine warm-up complete, runs hot as high as 240+ degrees; ambient temp approx 90+F degrees. The gas peddle position behavior is consistent; always more then 3/4 peddle travel, the engine bogs like all of a sudden there is less fuel being delivered.

After $2,500 spent the problem while a little better is not resolved.

where can i find the part number on the fuel pump

I removed the car's battery and now that is back the radio won't start. The screen doesn't say lock or anything, just the hour. I tried pushing 2 and 3 buttons together nothing happens. What can be done?

Replaced fuel pump today. Engine fires right up but dies immediately. It acts like it only gets the gas to start. I have spark. Fuel filter good. Relay good.

Showing incomplete drive cycle for evap, catalyst and o2. How do I diagnose and repair?

My blazer cut of on me while driving a week ago. All my gauges said I was good. Found out needed fuel pump. The next day while changing it there was no gas in tank when the gas gauge said I should have over quarter tank. Put 5 gallons in and put in new fuel pump. Now its reading different levels each time I start it. How do I fix this gas gauge issue?

Took your advice from other problems.changed distributer and rotor.car runs great now

did fire to coil to spark plugs blue 1/2" getting gas spray fuel in nothing did once befor set for a month and it started

Tried checking spark but it sparks are yellow

When truck is running

the car temperature was not running hot. White smoke steaming from underneath hood.

Have blown head gaskets and water pump is shot.

on when I crank it up it does it a little but when I push the gas the sound picks up and it sounds like popcorn popping. It seems to be coming from the catalytic converter area. Can anyone help.

This is an intermittent problem. Have had diagnostics done, said I needed a new computer, but when we picked it up from diagnostic (without replacing computer) it ran fine & has for over 3 months now. It's like they tripped something maybe? We have unhooked the battery, replaced the MAF, Throttle position sensor & fuel filter. New code is telling us we need to look at EGR valve. The codes are TP Sensor Circuit Intermittent Low Voltage, Fuel Level Sensor Circuit High Voltage, EGR Position Sensor Circuit Low Voltage, Fuel Tank Pressure Sensor Circuit Low Voltage... Any help would be appreciated.

Several times I use the remote to unlock the car and the alarm goes off, the car will not start. The security light keeps blinking. After 10 minutes or so, I try to reprogram the passlock and the light will go out and the car will start. I would like a quote to bypass and use the key only.

RPMs go up but it has no power. Check engine light came on once but went right back out. That only happened once tho. Replaced fuel filter but still has the problem

The fuel is getting to the carburetor but not in it, I poured gas in the carburetor and it starts, what is stopping fuel from getting to cylinders?

resetting the passkey and my security light only flashed 3 times ,new battery,plugs are firing, have gas,took post off battery to reset don't want to keep spending money i don't have .It is a 4 door 4 wheel drive 4.3 will turn over just won't start
