I would do a compression test and if okay change out the spider injector with a new unit which is common, these guides can help, and I have included the instructions of the changing the injector out to help fix the problem.

The compression should be above 120 PSI and if so, here is how to change out the injector. Check out the images (below). Please let us know what happens.
