I have a 1994 Dodge Ram. It drove fine yesterday, and when I came home, I parked it in the driveway. Today, it won't start. I've changed the coil, tested the spark plug wires, and still nothing. The wires and coil are not getting a spark. I've driven it for three years and every time, it would start right up. Now, with no warning signs at all, it won't start. It cranks, but it won't turn over. The battery is a good battery, and there is gas in the truck. What would cause it to do this?

 

fuel pump?

 

Ok, so I've checked the engine codes, as well as some other forums, and it is starting to sound like it could be the crank or cam sensor. My question now is where are they located on the engine?

 

crank position sensor is on the back side of the block, passenger side, stuck down into the top of the bell housing. near the oil filter. hard to get to.

cam position sensor is inside (?) the distributor.

check all your fuses, including the main engine, IOD ? , etc.
