I have an 84, and mine only opens if you turn it to the left. I put
the key in, turn it about 110° to the left-counter clockwise until it
stops. At thsi point it seems that i has no worked because nothing has
happened. Then I press the button in. Still nothing. However, if you
then try to pull up on the trim around the trunk lid, while holding
the button in, it will lift up. I don't know if that is by design, or
if there is a spring that would pop it open that has become weak, or
what, but that is how mine works. Try pushing that button in and
To expand on what tiger said about the engine not shutting off. These
cars run lots of things on vacuum including power locks and climate
control. The engine uses a vacuum actuated diaphragm doohicky to push
on a linkage attached to the injector pump that shuts off the flow of
fuel. Your problem is either that that part has gone bad, or more
likely that you don't have vacuum going to it from either a leak
somewhere else, or because the vacuum line going to it has come off.
search this list for info on troubleshooting that. There are two
orangeish/brownish vacuum lines that go into the firweall. One
attaches to the rest of the harness, the other to this part in
question. get a vacuum tester and figure out what is going on.
Glow plugs only warm up the engine prior to and shortly after startup,
and would have nothing to do with it refusing to shut off.
