So I thought I blew my motor up and pulled it. It sound super werid. I pulled the motor and got a 4.7l out of a 2002 dodge ram 1500. Someone said that the new motor I put in might be a high output motor. Could that cause a crank no start. New fuel pump, new crankshaft sensor and I'm pretty sure the 5 voltage wire is supplying 5 volts to the sensors. It wants to start but backfires and shoots flames out of the intake. The timming looks good but it just sounds super werid and need some advice.
