Question about 1991 Chevrolet Camaro

Open Question

Hey i have a 1991 camaro rs 3.1 v6 i got it back in april and about 3 to 4 weeks after i got it it started running real rough and wouldnt idle and when you got it out on the road and mashed it to the floor it would hardly go anywhere and well then right at about 5 weeks after i got it it died and now its been sittin since the last week of april. and now it wont do nothing at all it will turn over but wont fire. but the spark plugs are getiing fire. and we have also sprayed ethra in it and it still didnt do any thing we have also tried to put gas down the intake but that didnt work either. and iv checked the computer and all of that is fine. what do you think might be wrong with it. iv had a few people tell me maybe like a sensor or like the oil or gas pressure. what do you think?

SOURCE: 1991 camaro rs v6 3.1 cranks but doesn't continue to run

Here are a few other areas where you may want to check if applicable to your current situation.
I hope you can find out what the culprit is as I know how frustrating it can be.Here are a few other reasons why your car may not be starting besides what you have already mentioned.
Broken timing belt or chain (Belt failure will prevent the valves from opening. The engine will NOT run if the belt has broken, and it may have bent valves or other damage as a result of the belt breaking).
Broken camshaft (This can happen on an overhead cam engine if the engine has overheated, warped the head and seized the camshaft).
Plugged catalytic converter (Creates a restriction that causes exhaust backpressure to back up. Engine may start but usually dies within a minute or two)

I guess the most logical one in your case, after reading your story regarding when it happened would be a timing belt.

I had something similar to this happen on my '86 blazer. I was driving along and then "blip", at 55+ mph happily cruising along, the engine just cut out on me and wouldn't start again.
It would crank but wouldn't start. It ended up being an ignition module but you said they already changed your distributor so they more than likely checked or changed the module also.
Good luck with this!

SOURCE: 1991 Camaro RS v-6 will start but dies almost immediately

Keep it simple and replace the fuel filter first, if thr fiiler has not been replaced within 30,000 miles or 1 year. Then it's a good chance that it's going to be the fuel filter.

SOURCE: 88 camaro rs has no power to the fuel pump

Check to see if there's power at the fuel pump when cranking the engine. If no power, check the relay and oil pressure sender switch. If the engine looses oil pressure, it stops the fuel pump from running to protect the engine. The relay is located on the firewall above the master cylinder.

91 camaro rs 3.1 v6 will not start has code 12 and code 54

Well code 12 means you are in the test mode of the computer, so skip that one.
Code 54 is telling you the fuel pump circuit voltage is low, which could be the pump relay.
