Does it crank? If yes, do you have fuel pressure? Needs 55-62 psi of pressure.(Blazers eat fuel pumps like candy, and this one is inside the fuel tank) Is the check engine light on? May have a cam or crank sensor fault. Need to be certain before throwing parts at it. The fuel pressure test port is right on top of the intake manifold. There may be a factory security system that's been activated, do you have the key fob?

SOURCE: cannot start changing pugs and wires

Sounds like you have the firing order right but your off on the #1 on the distributer. Every time you get an explosion coming from the carb its misfiring. Find the #1 on dist and continue with firing order

Check the plug wire from the ignition coil to the distributor cap.
If you haven't already, replace the distributor cap and rotor.
The GM Vortec's have issues with moisture getting inside the cap and rotor and causing problems.

Should fire be coming out carburator with the air disconected when im trying to start it


Well you don't have a carb, you have a throttle body and injectors.
But the answer is no you should not have any fire there.
Could be some plug wires mixed up, or the intake valves are not closing.
You can check the firing order for the plug wires and run a compression test to check the valves.

Blinking Check Engine Light / Rough Idle


Double check the spark plug wire firing order. The cylinder have to have voltage in a certain order. If you do not have a motor manual you can google for this information. just write for example: 2002 ford taurus 6 cylinder spark plug firing order. The firing order goes in sequence usually in a clockwise direction. For example: 1, 5, 3 ,6 2, 4 in a clockwise order. spark plug #1 wire goes to the coil then spark plug #5 wire goes on the coil in a clockwise rotation, next to where spark plug # 1 was connected. This would mean that spark plug number 1 will fire (or get voltage), then spark plug nuimber 5 will fire (get voltage), then spark plug number 3 and so on. The sequence will continue to happen over and over again as long as the car is on. Here's another tip! When it nice and dark outside, turn your car on with the hood open and look at your spark plug wires for any voltage jumping from the wires to the motor metal. Keep in mind you may have to tent yourself with a cardboard to see the voltage arcing to metal. It has too be super dark for you too see this fault. Any arcing will cause your engine to misfire and your engine light to come on. Hope this gives you a starting point to finding the problem. Good Luck.

Chevy venture stalled


Compression, spark , timing , fuel for any engine to run. Don't forget a stopped up catalytic convertor will have the same effect as you described. Backfiring of course is fouled plugs, bad plug wires, look for arcing from wires when it is dark outside. If it has a distributor check for cracked cap, had my 91 GMC start backfiring then die due to ignition module inside distributor going bad. It would start back up after it cooled for about 10 minutes.

Changed plugs and plug wires and now it wont start


hope this helps double check Firing Orders

To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.

If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations.

2.4 pontiac wont start but cranks over


Do a compression test as a malfunctioning valve can cause back fire through the carbie. Since you have changed all the wires double check you have them in the right order because if they are wrong you could get a backfire.

1996 S-10 cranks but no fire


did you check to see if fuel pump is pumping. fuel filter isnt clogged is it? but you're sure there is no spark. because if there is spark it could be air flow problems.
and you changed the ignition switch so that's not it, how about the starter. is there any noise coming from the starter when you turn key? if it isn't lined up right.
there has to be spark if you did what you said take off a wire at night and try it . electricity to start goes, ign switch battery starter(is there a relay on s10s cant remember), the alternator is here also.to coil/distributor to wires to plugs to gasoline

also it could be the wires coming from the battery , check them for corrosion. if they are really corroded could be problem. and make sure your ground is good contact. ive seen corrosion inside wires causing no spark.
just a few ideas to check.
