I can’t get my Jeep to start I changed out the crank position sensor with a new one oem Mopar sensor set the timing on the distributor because the previous owner messed it up and it’s all set up right now I believe because the rotor is at 5 o clock and the index mark was at 0 on the pulley when I go to crank my Jeep it just keeps cranking no start back fires after a couple cranks and you can smell gas and new spark plugs put in I’m needing help

Yeah the Jeep Ran when I bought it I drove it home but it was backfiring po said the cps had been changed and water pump and new transfer case .i changed out the cps because I was told that could be the problem with the backfiring but it didn’t fix the problem also the tps was broke when I bought the Jeep so I bought a new one and the Jeep still cranked but backfired after changing these parts new spark plugs gapped at 35 still backfired I went to go crank it a couple days after the plug change and it wouldn’t crank tested the ignition coil with a spark plug and wire and the plug was firing orange so I have a new ignition coil on the way and a new timing chain because the Jeep has almost 158 thousand miles I put the Jeep at dc and made sure the index mark on the pulley was at 0 next I checked to make sure both valves was closed popped the dissy cap off and the rotor was pointing at 7 o clock so I pulled the cam sensor pulled the dissy set the slot in the block at 11 o clock dropped it in pointed the clamp at 1 o clock set the distributor in rotor pointing at 5 o clock bolted everything down
