Have replaced the fuel pump spark plugs and battery. It started after that but won't start again. Can anyone help?

Hi,

A crank no start condition is usually one of two things, a loss of fuel or ignition spark to the plugs.

We need to determine which circuit to focus on. Here is what I need you to do. See if the engine will start if you use starting fluid. If it does and then stalls, we know it is fuel related. If there is no change, then suspect an ignition issue. At that point, I need you to check for spark at the plugs.

Here is a link that explains how to check:

Let me know what you find.

Take care,

Joe
