1993 200 EFI FUEL ISSUES
I have a 1993 200 EFI that has always ran great. It has sat unused for a few months. I tried to start it today and am having fuel issues. has a new fuel/water separator filter and fuel filter. With the fuel filter removed, I can pump the ball and am getting fuel to the filter. The fuel pump kicks in when the key is on. I'm just not getting any fuel to the cylinders. I know that I am getting fire. What am I overlooking? can the injectors be clogged?

Are you getting spark to both banks? One of the switchboxes feeds the ecu. I had a similar problem once, had spark but no fuel. Had I checked both banks for spark I would have found the problem a lot sooner, ended up being no spark on the other bank due to a bad switchbox.

Make sure there is actually fuel IN the VST. Could be as simple as a needle stuck in the VST (or much more complicated, such as everything gummed up).
Note that the forum "one down" from this one is the appropriate forum for 2.5L engines.
