Question about 2000 Chevrolet Blazer

Hard Cold Start

2000 Blazer 4.3 Is hard to start when it is cold.
I have to try to start 20 - 25 times, when it does catch it sputters for a few seconds. After it warms up it will start first try. When warm it runs great, no missing. I dont know much about the newer cars and sensors and cumputers, but it reminds me of a choke problem.

My 2000 Explorer 5.0 engine is really hard to start.


Fuel can be a problem. There is a system called the "cold start sequence". This is an electronic solution to the old choke system. This system is triggered by the water temperature sensor. If the water temperature sensor is stuck on a warm mode, the engine will not have a choke.

You might change the fuel filter and check the fuel pressure. Check battery voltage too as sometimes weak voltage will make for misfires and as the alternator creates more juice the engine runs better.

Hard start cold, fine rest of day


I would be checking to see why there is power to the pump with the ignition off as this is a source to flat battery overnight.. May be a relay is still activated by a power source other than the ignition.

2000 ford taurus hard starting


Have a shop run a fuel pressure leak down test and have the engine coolant temperature sensor checked for proper colds engine value, if it is reading wrong for any reason then it can starve for fuel cold and it makes it hard to start.

2000 blazer having trouble cold starting in the morning. it's almost like it's not getting fuel to turn over...it feels like it wants to start but putter and turns off. mostly happens when the car is cold...


Have you the vehicle tuned up lately? Bad spark plugs will cause hard starting in cold weather also, the fuel filter could be plugged or it may have moisture in it. I guess, I would have those items checked and also, have the fuel pressure checked, the pump may be getting weak.

2000 chevy blazer takes about 10-15 cranks to start...fires with each crank, but won't start...


If its been a while sense you chg. fuel filter do that, if filter is not an issue than its best to do a fuel pressure test, fuel pumps are a common problem with all G.M. cars and trucks.
