Howdy, Try spraying stater fluid in the throttlebody and see if it cranks. If it starts thenyour having a fuel
delivery problem.

Side Note: This can be very dangerous and possibly start a fire.

RE: blazer wont start

Yes be very careful if you have to spray the throttle body.

If thats not the problem...
You think you have the timing right, you have a spark, and you have fuel. Next thing to check is compression. If you find that you have compression, you will want to double check your timing. Otherwise, make sure you intake is free and clear and make sure you are keeping the exhaust backpressure.
