I picked up this 91 Formula (L98) a few months back and the P/O took the sending unit and pump out to find everything was very rusty. This is how I got the car.

I just finished installing the new tank, sending unit, pump and fuel filter and am attempting to start it. Before installing the new stuff, I did test it (on the car, using a bucket of clean water to ensure the new pump/sending unit worked. I also removed the lines from the fuel rail and and blew everything out with compressed air before installing any of the new stuff. I also left the lines at the rail open and primed the pump, ensuring that I've got gas to at least the fuel rail.

I'm trying to start the car now and she's not getting gas - I checked for spark, and I was able to semi-start it with a shot of gas in the intake.

Ideas? Could my rails/injectors be clogged that bad to where it won't start?
