Have my 89 yj that I need to get running. About 8 years ago a "mechanic" ripped the 4.0 straight 6 and wasn't nice enough to put it back together :| now it's up to me... And I haven't the foggiest idea where to start... If u have a working 4.0 I would like if u guys could post some pics of... Everything just to get me started. My biggest problem is I don't know where everything plugs in so the help will be much appreciated

Thanks

the biggest problem you might have is the 89 didn't have the 4.0, it had the 4.2.

is it carb'd or fuel injected?
is the engine complete, disassembled or just removed from the vehicle?

more details and pics will go long way here

Thanks for clarifying the size. It's all together.... I think it's all jumbled up in the engine bay. I hooked it up enough to turn it over but that's it. There are still a lot of loose wires all over the place..... And it's a carb

Junk yards are always good learning spots. Maybe find some XJ's with similiar drivetrains. take a camera. works for me. I know not many wranglers make it to the yards.

?? did you pay the guy or was it a "friend of a friend" kinda deal? sounds like one of those rare occasions when a lawyer might be useful

Get yourself a Hayes or Chilton service manual. They are less tha 40 bucks and it will cover servicing the whole jeep including the engine. Will make things a lit easier.

if they don't' have emission inspection where you live, google "nutter bypass"
it will help eliminate some wiring and vacuum lines, especially if it is not the stock carb

otherwise, post some pics of what you are starting with
