Ok I am having a problem starting my hemi in my 72 challenger. Here's a little background. I bought a 2004 Durango that didn't run but I was going to get the engine rebuilt. I had the engine rebuilt and put it into the car. I had a new wiring harness built and I got a computer out of a 2005 Ram with a 5.7 Hemi. The computer was flashed and I had it double checked and the computer is not the problem. I put all new sensors and multiple times understanding a new sensor could still be bad. I replaced the Crank shaft sensor 3 times and the Cam shaft sensor twice. I also replaced the throttle body twice because the first one came from Rock auto and was told their electronic parts weren't that dependable. It sometimes take up to a minute or more to start then it runs ok but a fuel injector engine should start up right away. The only code I get is for the Crank shaft sensor. Any and all help will be appreciated. I have a video of it starting but it is too big to post on this forum.
