Describe what it is your doing when you "mess with" the MAP sensor, or Vac lines.

 

Try the hybrid or tech forum. This isnt really AM Forum content.

 

when i use the map sensor thats on the fire wall and attach the vacuum lines to the manifold i can get it to start but when i use the map sensor thats on the tb and i plug the vacuum ports off on the manifold it wont start ive tried to find a vacuum diagram but havnt found anything for a setup like mine.

 

Tell ya what, try posting in the Hybrid or Tech misc forum as CC mentioned. If you need repairmanual diagrams try HondaHookup.com for PDF versions of the Helms manual for your Car/Engine.
