MAF P0100 + P0325 knock sensor codes

  • 2.4L
  • 4 CYL
  • 174,000 MILES
I received these codes however have since changed (brand new) the MAF sensor, distributor cap, spark plugs, and air filter but none of these have fixed the problem being my car wont start up. I had a local mechanic come check it out and he started it up by creating a new bridge with the spark to the distributor I guess. This lasted about a month then it shut off again and wont crank back up. I've also noticed that when I tried to clean the last MAF sensor the spray I sprayed through to clean it kind of started it for 3 seconds then it cut back off. Sort of like it was feeding the fire.
Can someone please help
greatly appreciated

I am not sure what is meant by building the new bridge so if that got it to start then we need to investigate that further to find out what was done as that may help with figuring this out.

However, if you sprayed cleaner in the intake and it started then that is a fuel issue, so we need to check the fuel pressure to start.

The knock sensor code is most likely not causing this issue so we can ignore that for now. Also, if this is a MAF sensor, try unplugging it and see if the engine starts and runs.

I am attaching the info about the MAF code as that could be causing this.

Please run through this info and let us know what questions you have. Thanks
