A couple things you might wanna check...double check to make sure you have no blown fuses...assuming they're all good, it is possible your Mass Air Flow sensor could be bad/faulty...fuel line pressure check...make sure all the fuel injectors are seated properly and working...clogged/bad fuel filter...when you turn the key to run can you hear the fuel pump "priming" the system? If not, possibly a bad fuel pump...and/or faulty wiring.

Hopefully that helps...
Good luck...

SOURCE: 2002 Chevy Blazer, car will crank but not start.

it could be a fuel pump they are quite common on the chevy trucks and SUV's. If it has a "Vortec" engine which it probably does, they run whats called a poppet nozzle fuel injecter that requires i think no less than abaout 53 psi of fuel pressure to run, you would have to put a fuel pressure guage on it to be sure and they are quite expensive

I have a 95 Chevy blazer...just bought a new fuel filter and ign cranks but won't start unless I use starter fluid...can u help?

If you have the spider fuel system, I'd check that first. That system is noted for problems. Key on engine off fuel pressure-- 60--66psi ,
Also, the fuel poppet valves can stick.

I have a 2001 chevy blazer it wont start unless I use starting fluid after it starts it runs good I changed the filter and after it starts it runs good what could the problem be

If you mean the fuel filter then YES that could have vary likely been your problem .Its always good to change this these vehicles are known to have fuel pump issues and there a pain to replace and not cheap. Never let the tank run completely dry eighter you have a 2001 the pumps last 10 to 12 years at best so keep this in mind

95 s10 4.3 blazer new fuel injectors(spider) 2 new fuel pumps new filter was getting 50/60 psi on guage but had to start with starting only getting 10/20 psi changed fuel pump...

Problem is usually caused by the regulator in the spider head. It may not be installed correctly, not getting enough vacuum from the intake upper manifold or is failing. Start by checking the vacuum at the manifold.
