Acceleration problem with my Jeep Wrangler TJ 4.0

Have you done a compression test on each cylinder? Also as suggested I'd check your fuel pressure and make sure it is correct. It doesn't sound right in the videos.
 
If only he put TJ 1997 probably we already fixed this dude's problem.
But no no no no, he does not cave in. So it might be a YJ :(

@Chris. Please fix the title. The quibbling over whether this is a TJ or a YJ is getting stupid. If anyone is really still confused, just look at the videos again.
 
This is wrangler Tj

Your codes indicate that 3 of your fuel injectors are not functioning properly. Review this page to understand the possible causes and testing procedures.
 
at this point I replace the injectors and the pump and float which do you recommend?
because it often marks me zero even if there is petrol
 
Your fuel gauge issue is likely do to a float problem with the sending unit in the fuel tank. But it could also be a wire issue that isn't directly related to the fuel pump assembly. I agree with others that the first step should be to check the fuel pressure at the rail.

Also, you can get a factory service manual for your jeep on this website. https://wranglertjforum.com/threads...ice-manuals-fsm-technical-documentation.4618/
 
Jeep held production up in 96 due to federal mandated obd2 requirements in 96 and wasn't going to update the entire YJ electronics for just 1 production year when they had the TJ replacing it in 97. So there were no USA wranglers sold as a 96. The rest of the world did not require the obd2 system. So Jeep rolled out early production TJs over in Europe and I think Australia too. Then 97 model year the TJ was sold in the US.
