I have a 1995 Dodge avenger ES. The car had been running fine except for the fact that i had cracked the water pump. I changed the water pump only to now find that my car does not start. It cranks and if i give it gas its alright but as soon as I let the gas go the RPM drops to zero and the car dies. Because of this I have also changed the spark plugs, spark plug wires, distributor cap, distributor rotor. The timing on the car is perfect so I ruled that out. I think it might be my ignition coil??? any ideas???
