Thecar is only firing on two cylinders i put a new iginiton coil in but no change getting no spark on first and fourth plug
Have a mechanic check the timing on the car if its off you should know it will make a definite click ticking sound that increases with the rpm and also check the position of the coil on the camshaft!

95 excell, no spark on 2 & 3, coil replaced, leads & plugs tested.
check the 12v feed to the coils and the trigger wires to the coils. it maybe a faulty new coil, or leads and plugs, just because 1 & 4 are not firing it does not mean that those two plugs/leads are not faulty! with the engine running probe the coil pack wires with a power probe. you should have a solid red light on the probe for one of the wires wich will be the live to the coil. and the other wire/wires will alternate either green/red or green/clear to show the coil is being switched. if you have that then all is fine to the coils.
