My 1992 7.3 Ford Diesel Turns Over But Won't Start


The 7.3-liter Ford diesel is an engine with high ratings for fuel economy. If you are having problems with your 7.3-liter Ford diesel, you can do several things before you take it to a service center. Diesel engines are not very hard to work on. Most of the troubleshooting can be done without invasive repairs to the engine and minimal knowledge of how the engine works. Common issues reside in incorrect fuel, a bad starter or leaks from the engine.

Things You'll Need

  • Siphon hose
  • Empty fuel container
  • Diesel
  • Jack
  • Insert and partly turn the key, to engage the Ford electrical panel. Look over the fuel gauge and make a note if there is not enough diesel in the tank to start the engine. Low fuel prevents an engine from starting.

  • Replace the fuel in the tank with the proper diesel. Changing diesel according to the season is imperative. Summer diesel will be cloudy in the winter -- this is the presence of condensation in the tank.

  • Use a siphon hose to remove the diesel from the tank. Put one end of the siphon pump into the fuel tank and then put the other end of the siphon pump into an empty gas container. Pump the siphon until the tank is empty. Fill the tank with the proper kind of diesel fuel.

  • Raise your 7.3-liter Ford with a jack, so you can get under the vehicle. Look for the small box next to the engine block on the right side of the vehicle. This is the starter. Get a helper to turn the ignition. Listen to the starter while the ignition is cranking. If you hear a clicking or a buzzing noise, have the starter replaced by a certified technician.

  • Look around the Ford for any leaks. Leaks can inhibit the car from starting properly. If you do find leaks, have the vehicle towed, or drive it to a service shop to have the leaked repaired.
