2001 blazer wont start but cranks.....!
 

I have a 2001 blazer 4wd that wont start but will crank. I have changed the distributor cap and rotor. when i checked the core plug from the dist cap it was barely getting a spark, thats why i just put new ones on. i check the fuel pressure to to see if it was getting gas and it was. when i sprayed carb fluid into the intake, it starts but cuts right back off. ANY SUGGESTIONS ON HOW TO GET MY TRUCK STARTED........?

What was the fuel pressure numbers?

It was a lil above 40

Should be about 62psi,and not drop below 54 after 10 min, if it does not then fuel pump is probably bad would not be bad idea to change the fuel filter is well
