Where is this located on a 82 series 3? Want to see if it is closing and how would you do that? Also how do you test a cold start injector?

 

It is in the trunk, in the spare tire well. Item #5 in this illustration.

Remove it and blow thru. You should be able to blow thru it in only one direction.



Remove hose from the cold start injector. Remove injector from the inlet manifold. Re-attach hose.

Remove coil wire so engine won't start.

Have a helper crank the engine while you watch for fuel to spray out of the injector. Engine must be *cold*. It'll spray for only a couple seconds.

Be ready for a gush of fuel
