Has the fuel pump ever been changed? Possibly the filter on the pump is clogged. Or even the filter below the manifolds. Maby get a pressure testing kit remove your cold start injector and test the rail for pressure. Should be around 35 psi when the pump is on. Hold open the flapper in your afm to activate the pump

this manual is 1985/86 spacific. looks like you have an 86. i can only assume because of your user name.
