Rusty_Panda Posted Monday at 07:43 PM Share Posted Monday at 07:43 PM Hello, I'm trying to start my 2.8l 1986 mj and I noticed the egr isn't hooked up to anything as well as some lose vacuum lines. What all do I need to actually run the vehicle. If possible I'd like to attach them but I honestly just want my truck to run Link to comment Share on other sites More sharing options...
89 MJ Posted Monday at 10:18 PM Share Posted Monday at 10:18 PM (edited) Can you post a picture of the loose vacuum lines that you've got? Maybe a picture of the engine bay from the front left corner too? Just so we can look and see if anything looks out of place. On another note, to get it to run, you just need air, fuel, spark, and compression. Plug your vacuum leaks in the intake and carb, verify that you're getting those 4 things and it should run. Then we can focus on getting it running properly. Edited Monday at 10:26 PM by 89 MJ Clarifying what I said Link to comment Share on other sites More sharing options...
pizzaman09 Posted Monday at 10:19 PM Share Posted Monday at 10:19 PM If you just want it to run, plug all loose lines going to the carb or intake manifold as they will be vacuum leaks. Alternativly, you can start plugging them back in where they belong. The goal is to eliminate as many vacuum leaks as possible as that will give it the best chance of running.

Rusty_Panda Posted Friday at 04:15 AM Author Share Posted Friday at 04:15 AM With the help of carb cleaner sprayed directly into the weber carb its starting but only at 4,000 rpm. I will post the photos but in the meantime I've got to figure out how to tune it. 20250626_202252.mp4 Link to comment Share on other sites More sharing options...

llhat Posted Friday at 01:19 PM Share Posted Friday at 01:19 PM 4000? yikes, this with vacuum lines plugged? will it run 'off' of the cleaner? i think i see fuel in the clear filter... far from expert, but the choke is still engaged on the weber, this activates a 'fast idle cam' which opens the throttle plates at the base of the carburetor, increasing idle speed. ensure the fast idle cam disengaged and basic visuals for vacuum leaks. good luck Link to comment Share on other sites More sharing options...
