1987 grand am 2.5 liter. Was running and would stall. Sounded like cooling fan relay switch clicking on and off after stalling. Checked fuel relay and replaced pump and fuel filter. Vehicle will run when gas is dripped into carb. Computer also replaced. Just changed prong and replaced with old prong chip with negative cable disconnected, was it installed wrong maybe.

if you drop some gas down and it runs I would check your injector, it might have gone bad, or be clogged. if fuel comes out see how much does you may have low pressure due to a faulty fuel pump or a clogged line. good luck
