Failure to start. Turn key and get either the 'click clic click' of the solenoid not engaging, or a single clunk and all the electrical goes dead.
The battery is new and tests good. Wiggling the ground wires seems to affect whether I get clicks or clunk. Truck was driven without incident an hour prior to not starting. Used a continuity tester on the wires leading to the firewall, got inconsistent results, but even with good continuity, the truck did not start. It appears that Ford no longer sells the negative cables for this vehicle. Any ideas on where to start my search?
The newer Ford starters need good grounds and power to function properly, from what you stated it sounds like you have lost a main ground to the engine, double check the battery terminal connections, they should be shiney clean, no black corosion, if the cables are bad your local parts store should be able to get you setup with the proper cable types so you can replace them.
Thank you for your answer. The battery is brand new, as are the cable ends. I will look more closely at the connections on the firewall.
All 4 cable ends must be clean and tight.
