Many possible causes....Too little info to make an intelligent suggestion. Try charging the problem vehicle's battery with jumper cables for 2 minutes with the supply vehicle running at fast idle (or about 1500-2000 RPM, if it is tachometer equipped) before you try to crank the problem vehicle on a cold morning. If it starts right up, you likely have a weak battery that needs replacing.

    I have got a new battery, spark plugs, and changed the fuel line filter. When I try to start the car it sounds like a car that has no gas. If I pour the gas straight into the motor it fires up

    Obviously, you have a (cold) temperature related fuel delivery problem that is likely electrical in nature. When it is cold you likely have a circuit connection open and the fuel injection does not happen. When it warms up the connection closes, and the engine gets fuel and runs. THE PROBLEM COULD BE JUST ABOUT ANYWHERE ELECTRICALLY RELATED TO THE FUEL SYSTEM AND WILL LIKELY GET WORSE WITH TIME AND VEHICLE OPERATION. A code reader scan may help pinpoint the location. Likely locations include being related to the fuel pump, the fuel injector solenoid, and the ECM (Engine Control Module). GOOD LUCK.

Chevy 2005 tahoe z71 blows cold air in back but hot air in front


Just got an answer from Chevy Dealer. When you replaced the battery it loses its memory as to where the door actuators were (the flaps that control the heat and A/C).

The fix:
Turn everything off and let the car sit overnight. The computer should reset itself during its learnings process.
In the morning turn on the ignition and let the car run for a few minutes before turning on the climate control.

If this doesn't work, plan on 1-1.5hours of labor for a technician to reset the actuators at the dealership.

Good luck.

Have a '94 S-10 Blazer Tahoe 4X4 and it starts


My suspicion is a starter going bad. Sometimes when starters get old and worn they will start good when the engine is cold but not when the engine is warmed up. Did you perhaps notice that lately is seemed to drag when you tried starting, especially warm or it seemed to crank a little slower? I'd replace the starter. Hope this helps.

1999 chevy tahoe 5.7 wont start in the am without starting fluid but as long as you start it every 1/2 hr or so it starts fine. runs good once started any suggestions?


check fuel pressure. If its marginal then replace the pump. These trucks are touchy on fuel pressure. Just a couple psi low and they do exactly this. In the morning cold is when you need max fuel. Be sure to replace the harness also as these tend to lead to repeated pump failures when faulty, which is pretty common
