Auto does not start

Can a partially clogged escape system be cause for a car not to start?
I have a problem with my car, it does not start with anything even though it seems that everything works well, carburation, spark, engine time, etc. I noticed that the exhaust pipe has a blow and folded, I will repair it anyway but this could be the cause that the car does not start? Thanks for your help

It is very possible that the obstructed escape as a problem to start the car but did not mention if you have taken the compression and the state of spark plugs as well as the state of the starter engine, if it has enough strength and speed when connecting it fix it and looks there on that side.

I add some more data:
because it is a Nissan Sentra Model 1985, E16 engine, 4 cylinders, carburated, ignition without platinum, mechanical. I tell you that I already checked the gasoline pump disconnecting the hose between the carburetor and the filter, when the starter motor operates does pump gasoline, I did not measure the pressure but an acceptable drizzle comes out, the pump is mechanical of the membrane type, in addition the tank of the carburetor is filled to the exact level (the carburetor is a progressive nikki). I checked the 4 NGK BRK5es spark plugs by taking them out of the engine and with the cap put a intense blue spark, so I suppose the coil, rotor, distributor and cables are fine. Compression and time are exact with the rotor position. The rotor rotates correctly.
The problem I have is that although everything I mention is fine, it does not give signs of starting, I changed spark plugs and I get wet from gasoline, I suppose it drowns when trying to tear it away. I put some clean and the same.
I tried to throw a little gasoline in the carburetor and it didn't work either.
I have broken my head trying to see what it is, this engine is one of the most basic and faithful that you can imagine. Despite being old I have it in very good condition. I arrived at my house normally without fault signs. The next day I wanted to start it and I have been with this for 3 days, it does not start.
Seeing under the Auto I noticed a deformity in the escape is almost closed although not totally, it was surely a blow to a parking lot, but I just hit the escape nothing more.
I would thank you for a bit because to lead him to fix the escape I need to start it and I would like to know if this could influence not starting. Thank you

If you tubed the exhaust stuck, the gases would turn to you back and you would see it very well giving it with the removal of rockers remove

Won't you have the ignition out of the point?
