Hook up a fuel pressure guage. Now with the key on and engine off does the fuel pressure come up fast and hold steady at a fixed value?

SOURCE: 2000 chevy blazer takes about 10-15 cranks to

I would take a look at the ECS (electronic coolant sensor). It has 2 wires connecting to it, 1 yellow and 1 black. If the sensor is not reading coolant temperature properly when the engine is cold, it will cause a lean cold start condition, spit and sputter until it cranks enough times to catch itself. A resistance check can be made on the sensor to verify sensor is correct if you are interested.
Let me know.

96 blazer.4.3 ltr 4x4.new crank sensor.new fuel filter.new coil.got fuel and spark.still won't start


How about the fuel pump...are you getting the fuel to the cylinders? Is the fuel making it through the fuel line through the fuel filter? Drop a few drops in 1 cylinder, if it fires, you have a fuel problem. Does it turn over? If not check out the motor starter!

Check for fuel pressure and check for spark during the no start condition. Also check the crank sensor, it is located behind the crank pulley mounted in the engine block on the 4.3 L engine

98 Chevy blazer won't start up but will crank ,,


Try giving it a shot of starting fluid. You don't say if it's actually firing. If it tries or runs for a few seconds off of the starting fluid then try changing the fuel pump relay. It's inside of the glove box on the left hand side behind the little door. If that doesn't work it's most likely the fuel pump.
