Same problem before you changed the injectors? Is the cat clogged?

You have to understand that what you described could literally be a crap-ton of things..

We usually can only help after you performed some basic troubleshooting yourself...

We need a lot more history..

The problem started a month ago I changed the injectors under the belief that it was them but no fuel to them still. Cats fairly clean for a 2k but there's med/ high pressure from my engine when I remove the cap there's suction

You need to see if you have the right fuel pressure at the fuel rail with a mechanical pressure gauge. You should have 49psi +or- 5psi.

Ok eff it motor swap maybe upgrade best next step ??

RTorrez1

Have you check the fuel pressure. It may be a bad fuel pump. Really can't give much more advise until you do some testing.

your jumping to a huge conclusion... do you have the mechanical knowledge to diagnose this yourself?

If not take it to a mechanic and pay them the fee to diagnose the problem, then let us know and we can give you advice on how to repair it!

Low press says my mech but he also says it's the valves I'm thinking about upgrading engines just so it can be solved found a 350 but I'm not sure if it fits I know I would need mod to make it fit though

HEY! Since we are trying to tie shoestrings with chopsticks here in OEM TECK, why not stab out nearly meanness thoughts with thumbs, (punctuation only helps clarify your thought), and just to make it more absurd, why doesn't someone say "buy new everything", or "just take it to a shop, they can fix it.

I think clear descriptions of problems, (hopefully not common ones), by the poster, and direct responses to the posters Jeep issues belong in in OEM teck. Alphabet soup and personal feelings are not part of zeroing in on a technological problem. OK Don is grumpy. My weed wacker only wacks for 10 minutes

If all it needs is a fuel pump and maybe a valve job, it might cost a few hundred bucks.

Or you might drop in a 350 for a few thousand!

RTorrez1

If you can't fix a fuel problem and pull the head to do a valve job, What makes you think you can modify it to drop a 350 in it???
