Techron full system cleaner made my car crank but no start

[Limitz]

So I used Techron full system cleaner on my car, was able to drive from gas station almost to my house (legit a street from my house) before car started “giving out” as it started pulling back and didn’t want to go , would get stuck at around 2.5k rpm’s. Pulled over and then my engine died , I was able to turn it on right away, take it home and I left it overnight, the next morning tried turning it on and it’ll just cranks. Now I got two error codes one was fuel and air ratio code and the other was a multiple misfires. I’ve checked the fuze boxes, everything good they have current and none look bad, I’ took the maf sensor off to look at it , and it looked good and clean, the throttle body was a bit dirty so I cleaned it, still only cranks. The only thing I can think of it being is the Techron cleaned all the gunk and shit I had in the gas tank and my fuel filter collected it and got clogged up. I’m trying to measure the pressure of the fuel with a gauge but for some reason our cars don’t have a valve to plug the gauge in for a reading, I was told to plug in directly to a fuel line ? And also how should I go to changing the fuel filter if my gas tank is full, better off having a mechanic do it ? Also this car has 105,000 miles on it I believe you gotta change the fuel filters at 75k miles and I’m sure the old owner never did that which is another reason I think the fuel filter is clogged but wanna run tests to pinpoint if it really has to do with the fuel pump

Bad gas is more likely....
