4 fly 8 plugs. Replaced plugs and wires. Would idle after this but above idle would backfire or stumble. Now turns over but will not run as if not firing.
Any help would be appreciated greatly.

Hi,

In most cases, it is either a fuel-related issue or a loss of ignition spark to the plugs. We need to determine which one it is.

To start, see if the engine starts for a couple of seconds using starting fluid. If it does and then stalls, we know it's fuel related. If there is no change, then we need to check for ignition spark to the plugs.

Here is a link that explains how that is done:

If you have both spark and fuel, then we need to consider engine compression and ignition timing.

If possible, record it cranking and upload it for me to hear. I can usually tell if there is a timing or compression issue by listening.

I will watch for your reply.

Take care,

Joe
