Stuck injector

Stuck injector well i figured out why my starter was grinding. Pulled the plugs today, and fuel GUSHED out of the cylinder on the drivers side closest to the firewall. So, basically the motor was hydrolocked. I then cranked the car over with no issues with the plugs out. Then, i pulled the fuel rails up a bit, had a buddy prime the pump, and that injector GUSHED fuel until i had no fuel pressure left. So, i guess it is stuck open? Any way to fix this?

Ford injectors are supposed to fail closed... So that's weird :\ Only way to POSSIBLY fix it, like if a piece of carbon or grit got in it, would be to tap on it while the pump is priming. Then again I'm sure I'll get ridiculed for suggesting such a redneck method 
EDIT: Oh forgot to add you should PROBABLY check your flywheel for missing teeth.

Yeah I wouldn't do that very long, that's a big step to ask the PCM to compensate for with pulsewidth changes etc.... you might wash the cylinders down with all that extra gas removing the thin film of oil which then lets the rings scratch the **** out of the walls....buyin a xtra set of injectors would be cheaper...

Yes, that is just as bad. Your choices would be to purchase an equivalent single injector, send that one in to be repaired (if they will do just one) or purchase the 42# with an immediate tune, such as a mail order tune.

Ah, I did not see that your sig states 30# SVOs. My bad.

Dealer NO. Sponsor YES. Stay far, far away from the dealer for almost everything.
Go to the Fueling/Injection section. There are sponsors who do injector rebuilding. Just explain to them that you are going to upgrade the injectors in the near future so you only want to have the one rebuilt.

if i cant find one direct from ford, I should have no problem using an injector from another brand, as long as it is 30lb/hour correct?
Was thinking of just picking up one of these to hold me over until later in spring:
