I have a 2000 mustang with a 3.8l v6. I broke a head bolt in the block, I got a 2001 v6 and I kept the bottom end but used the heads and intake ect to put it all back together. Now I've got it back in the car and it'll turn over but will not start. I have a new coil pack, plug wires, and plugs. I have ignition power at the coil pack and the crankshaft position sensor is also good along with every fuse. Anybody have some insight on what may be the problem
