Hey! I have A 2001 chevy blazer 6 cylinder. And when I turn the key and crank it, it fires a little and then continues to crank like its not getting fuel or spark, no ignition. But if I turn the key to start for just a couple cranks and quickley release to the run position it putters up to life and runs fine once it's running. Takes a few try's and it's A little tougher when it's cold. Does anybody out there have any ideas?????

 

Welcome - and Happy Thanksgiving
Check for spark during the no start cranking - ignition switch could be starting to fail or be out of adjustment.
Next do the fuel pressure testing in the stickiey in the second gen section. Do all steps do not skip any.
My Morf when I first built her was doing somewhat the same - In her the check valve in the fuel pump was failing. pressure would bleed down instantly after pump cycled and the same as you I had to instigate a early key in the run position for it to start.

 

Checked fuel pressure. that's fine. Have not check spark.But that what it sound like. I was thinking maybe it had something to do with the switch also or maybe something with the antitheft associated with the lock cylinder.. Thanks for the input!

 

Sounds like the ignition switch. There is a good how to on YouTube. I'll see if I can find it.

 

 

 

Ignition switch it was. Pretty easy install also Thanks y'all for the input.

 

Glad you got it figured out 👍
