2023 C4 of the Year Finalist - Unmodified
His car was running - albeit less than optimally.
He changed the Opti 'cap' and broke something in the process.
He seems the have spark thru the plug wires. The engine will turn over but not run.
He has fuel in the tank and the pump is running, but doesn't seem to have verified if it is coming into/through the injectors.
He may not have double-checked his work to make sure nothing was left unplugged.
I also can't read that he has put the old 'cap' back on to see if it was the failure point.
May be still drunk or high or both.

No not neither am i, MAYBE should be but aint ! Sorry about how i texted that, I couldnt see the screen from were i wuz , but let me start over again. i just got this 94 corvette, keep in mind, its my first one and i drove it home, but it wuz misfiring, the man told me hes changes fuel pump, and couple of orther things, hes used it for five yrs going back and fourth to work, until it started misfiring and he sold it to me because hes done with it, so thats how i got it , and myself doesnt no much about it too, but he gave me a new rotor cap that goes on the optispark and said thats why it misfiring as far as he knows, so i changed the cap, and it look like he would have been right, because it wuz so bad , im surprized it run! and i put it all back together and now its got fire threw every plug, but want hit a lick, and im stuck not knowing what to do, any ideas could help , remember its my first one and im learning too, please help if can

Gas, air and spark in the right amount at the correct time and it runs. If it does not run one of those is missing, wrong amount or wrong timing.
Basics, check if there is a code stored. How to read codes post all over this forum
Fuel pump running (making noise) does not equal enough pressure, get a gage and confirm
given you just worked on it, double check all your connection to make sure they are tight
you said had spark, how did you check that?

All right calm down, just busting your chops. From what I can understand in your first post, you changed out your Opti cap and now the car won't run. Correct?

Posts like this are just a sign of the times. Millennial's and Z's get on their phones and start two-thumbin' it like a woodpecker on a diseased oak. No regard for grammar, sentence structure or continuity of thought. Then they get all butt hurt when people who are cable of typing organized thought call them on it.
