1994 Pontiac Grand Prix Fuel Injectors

I bought a 1994 Pontiac Grand Prix Special Edition Coupe 3 days ago and I drove it for about 2 hours. I took it to my dads house to give it a bath and I sprayed under the hood around the edges to clean out the gunk from leaves. After I finished I drove about a half mile down the road after the car started up just fine. At a stop light the car just stopped. It would crank over yet no fire. The gas gauge didnt work so I thought it was out of fuel. I push it to the gas station on the corner and I find out the tank was almost full. I get the engine to start for about 3 minutes and it died again. Since I cannot get it started. It starts on ether but thats it. I changed the fuel filter and I get fuel pressure on the rails so it is not the fuel pump. I believe it has something to do with the injectors but I dont know what would cause them not to pump fuel into the cylinders. I tried replacing fuses but nothing seems to work. Anything I might have missed? Thanks for the help!
