Question about 1988 Pontiac Fiero
You will need to put a fuel pressure gauge on the line going to the carb. Running, you should read about 5-7psi. If you don't have a gauge, disconnect the line to the carb and put a length of hose on the end, place other in in a gallon container and start the car...you should have at least 1/2 gallon of fuel in the container when engine stalls. I am fairly certain that there is a filter right inside the carb fuel inlet. Make sure the filter is clean. If after testing, you find that either you have bad pressure or delivery from the pump, replace the pump. Also make sure that all undercar lines are not leaking...even a pin hole in a line will cause the pump to draw in air instead of fuel. Blow air back through the line to make sure there are no leaks and that the tank "sock" filter is clear. good luck
