Alright. Long story boring, this is not my rig. A friend hired a meth head to change the oil pump (why? I don't know.) and the dude muffed everything up. So after four days of correcting everything he ruined I got the engine together, plugged everything in...aaaand the engine won't start. Yes it turns over, and yes the fuel system is working. I haven't got around to checking spark yet though. I suppose I'll try it tomorrow. Let's assume for the moment that it does have spark.
So...WTF? What are the chances that it could be the crank position sensor?
