I have a 1997 neon I took sohc engine from a 97 neon and put it in a 97 neon that had dual overhead cam engine and it hooked up just fine I started it up and was adding anti freeze and it just stalled and now it wont start. the codes said bad cam position sensor I replaced it and same problem I pulled fuel rail out and it only shoots fuel out of one injector and plugs only fire center 2. Does anybody have a idea how to fix this problem. Thanks
