Pump is on but injectors wont fire



we have an 83 Trans Am w/ the Crossfire Fuel Injection and when we try to start the car it just cranks and cranks and cranks and cranks.... no fuel... when you turn the key to on you can hear the pump prime the fuel system but when you goto start it there is ZERO fuel coming from the injectors.. you cant even hear them clicking... its not a fuel filter as this car no longer has one, yeah dumb but the old one was seized to the line, and we are getting spark... no fuel...

any suggestions will be helpful we want this car back and going as soon as possible, its also my dads ride to and from work everyday.

My guess would be the stupidity of no fuel filter on there has plugged the injectors.

i doubt they would both plug randomly... my dad drove the car to work yesterday morning w/ zero problems and he said it was running great and then we went out to leave work and it wasnt firing injectors.

the pump died on us about 6 months to a year ago on us and we had that replaced w/ a new one and a new sock so junk shouldnt be in there.

well you never did say anything about it being a random problem...

But your still stupid to be running without a filter. The screen on the pump isnt going to block all of the crud!

why are we continuing on this... its not clogged... nothing is telling the injectors to fire... we were just told one more possibility... ignition module... who else agrees.
