I replaced the engine with 1 out of a 1995 Dodge Ram van but I had problems getting the crankshaft wheel to align to the flywheel. I finally got it to bolt up but I think the wheel was bent in shipping. Well long story short the truck wont start. It cranks and fires but seems like the time is off. When it does start it backfires and sometimes afterfires then dies. Would a bent crankshaft sensor wheel cause this?
