Sorry, my bad. You're stuck buying the whole spider assembly, then. Weird, because it looks exactly like a TBI injector in there.

 

Yes that's what I was trying to avoid but seems like that's the problem. Fuel constantly being "opened"to injectors. I believe that harness open and closes the maxi through pulses from ignition coil. That way it's not a constant flow to cylinders. New reman assembly ordered. Now to get that excess gas out of the cylinders..
Maybe there's a way to test that maxi injector, just to make sure.
