I just replaced the 5.7 engine in my 1500 4x4 it started and ran pretty good then noticed hard starting like it wasnt firing so I checked all that I knew to check found the crank position sensor wasn't plugged in started fine and drove all day yesterday with no problems. Now it's acting up again hard to start and when starts the rpm gauge jumps and oil pressure jumps then shuts down and then acts like its not firing.
