No crank condition

Post by convertables_10 »

I had a firmware corruption issue yesterday that wiped out my fuel table and more. I reflashed it on the side of the road with the same firmeware 2.890 as i had flashed it with before. It ran ok on the way home. Got home and started resetting the setting i needed for cold starts. It started a few times and now it just spins over. It has a tach signal cause the injectors are firing. Plugs was wet as well. Ignition is brand new outside of the distributor base. MSD cap Taylor wires autozone coil autolite plugs. I just got a set of injectors i was going to install with a new fpr as well. Pulling the ecm is next up as well to check it for bad solder joints and more.

Does it have spark?

You may want to try reloading the firmware and a map from before when this happened; see if that helps.
