1998 suzuki swift

:frown: I replaced the oil pan gasket removed the crankcensor then put the car back together. Took the car of the lift and it would start just turn over and back fire. chedked the if plugs and wires were firing. The plugs would fire on and off. The car is firing one injector. I replaced the crankcensor no luck. I was told these cars have a wiring harness problem. I checked the harness for any fraided wires I could not see any problem and the fuses were fine. Could anyone help me with this matter.:banghead:
