I have a 2002 Grand Prix 3.1 liter that won't start. I have spark and it will hit with starting fluid. I have 59 psi fuel pressure on the rail. I have 12 volts on the pink wire to the injectors which tells me I must not be getting an injector pulse, to verify I would have to remove the upper intake. A Mechanic gave me an ICM to try and I have same symptoms with it. G.M. Mechanic says the crank sensor is good or I wouldn't have spark. Any ideas?
