I have this truck I cannot figure out why it is not running. It gets spark and fuel and the engine will turn over but it will not start. I thought it was the crankshaft position sensor but I couldn't find it on the vehicle. So I bought a book and low and behold... It has neither a crankshaft nor a camshaft position sensor. I'm trying to get it running again to sell it as I have pretty much given up on it. A little bit of help would be much appreciated!
