95 geo tracker starting problem

i have a 95 geo tracker, new altenator, new battery, new distibutor cap and rotor. i went away for a weekend and when i got back it would not turn over. it would try it is getting spark and gas but will not turn over. i use this car daily for my job and have not had this problem before. it has been raining alot so thought maybe moisture got in ditributor cap so replaced that. i dont know where to go now any suggestions…
