i bought a 1988 YJ with the 2.5l engine that won't start. It has a new fuel pump and fuel filter but I'm not getting any fuel in the throttle body. Are there any videos on how to remove the throttle body so I can take it apart and install a new fuel pressure regulator and gaskets? I haven't found anything. I could figure it out but I am trying to avoid taking off more parts than necessary. lol

The factory service manual should have instructions

Hi from the UK.
I took my TBI apart on my 1989 2.5l to resolve a vacuum leak between the TBI body and the intake, the paper / card gasket was virtually gone, so the whole thing whilsted at high speed!
I replaced it with blue sealant we have in the uk, lightly spread over both surfaces of the TBI and the intake, torqued it back up and let it 'heal' for a couple of days before taking it out. Never had a problem again in that regard.
These are the only pics i have of that little job - may be of some use?
Cheers!

Ok, that helps. I see how it's mounted now.
