for the past 2 years my car has gotten harder and harder to start and now will not start. for the first five years my car started immediately. 2 years ago it started to take two tries to start it. 1 year ago it started to take 3 tries and very specifically just bumping the starter quickly three times, the third time it fires right up. finally now it will not start at all, bumping it every 4th or 5th time it gives a weak attempt to run but nothing. have changed the fuel filter a few times, new battery, cleaned the fuel injectors., new spark plugs, no change at all whatsoever
I think i have a fuel delivery problem but do not know chev blazer,2001, 4.3 l vortec?
If the engine rotates but, won't start it can be quite a a few different things.
It can be:
fuel tank empty
fault in the fuel injection system
battery discharged ( engine rotates slowly )
battery connections loose or corroded
faulty fuel pump
excessive moisture on, or damage to ignition components
worn, faulty or incorrectly gapped spark plugs
broken, loose or disconnected wire at the distributor
distributor cap wet,cracked or carbon tracked
ignition coil bad
and last but, not least and the most expensive problem...
engine mechanical failure.
Lots of things to check here, good luck.

well, as a blazer owner, the fuel pumps are infamous for going bad. However, since you said its gotten harder and harder, I would suggest checking your power wire going from the battery to the starter. Does it turn over when you crank it, or does it just give a little clunk? If that wire is corroded, it will not give the starter enough power to get your engine to crank over. If its manual, try pop starting it.
