sounds like a dead short in the tach wire, trace the tach wire and see if it the wire insulation has been broken.
ingnition switch locks up on 2003 Ford Mustang and only way car will start is if you can turn steering wheel back and forth to get ignition key to turn
My guess would be a defective ignition switch.
With a key, by turning on ignition
The Mustang was originally mass produced in late 1964, but Stang concepts, called the Mustang Roots, were made in '62 with a German V-4 engine.
your battery is dead
ensure there is diesel in the car. Turn on ignition but don't start the engine yet. Watch dashboard and look for a small light (not ignition light) look for a heater plug light. When this goes off then turn ignition full turn and engine should start.
may be a bad starter..... or if the engine is cranking with no start it could be the ignition wires
Yes, a bad coil will prevent the ignition from firing and the engine will not start.
Try an ignition switch.
A bad ignition coil will cause your engine not to have any spark. Without any spark the engine cannot start or run.
The ignition module will send a signal when the key is turned. If the module is no good the signal is not sent to the other ignition parts,thus not allowing the car to start
Press and hold the trip set knob (inside the speedometer) until it reads 0000, and while holding it try to turn the ignition key to acc. DO NOT START the engine. The messege will clear
