Driving fine and boom shuts off out of the blue. I had to get it towed back home. I figured it was a fuel issue. I changed the fuel pump and fuel filter. No start, then I change ignition control module. Still no start.

Hi,

In most cases, a crank no start condition is the result of either a fuel loss or ignition spark loss issue.

Do me a favor. See if it will start with starting fluid. If it does and then stalls, we know it is fuel related. If there is no change, we need to check for an ignition spark at the plugs.

Here is a link that explains how that is done:

Let me know what you find.
