Hi, I have replaced crank and cam shaft positioning sensor and have fuel. What else could cause it to run then shut off and not be able to start again for a couple of days then same problem.

Hi,

Randy, when it doesn't start, I need you to try something. See if it starts using starting fluid. If it does and then stalls, we know its fuel related. If there is no change, I need you to check for spark to the plugs.

Here is a link that you may find helpful:

Do this so we know which direction to focus. I'm just trying to narrow things down.

Take care and let me know what you find.

Take care,

Joe
