My engine just stopped one day and hasn't started since. I got a code reader and the first time it gave codes 67-10-11. I tested it again the next day and now reads 67-10-96. I know very little about cars but I found out that 67 is the nuteral/drive safety switch. If the truck hasn't moved or even started how and why is code 96 coming up and what can I do now?

Hello my name is Dave.

First thing we need to know is does the engine turn over? I it does then the the neutral safety switch isn't causing the problem, if it isn't turning over I would jump the starter solenoid to see if it starts. The solenoid is right by the battery on the inner fender and the pole you need to jump is the small one marked with an "s", simply supply 12 volts to that and it should turn over. If it is turning over and has no spark there are several possible causes, first one I would check is if there is power to the ignition coil, if there is then I would check the ignition module that is on the side of the distributor, if you remove it most auto parts stores can test it for you. The next thing I would check would be the ignition coil, most likely if the module is good then that would be your issue, keep in mind all of this is assuming that your problem is that you aren't getting fire. I hope this helps you track down your issue and thank you for using 2CarPros.

I have replaced the spark plugs, distributor cap and rotor, plug wires, ignition coil. The starter does try to start but there is no spark from the ignition coil to the distributor.

Could it be the secondary ignition coil inside the distributor?

These have the soft film ignition module that goes out. Here is the instructions on how to change it out in the diagrams below. Check out the diagrams (below). Please let us know what happens.
