Why won't your 2000 dodge durango fire it's turning over but not firing?

Answer 1

Assuming that by 'turning over' you mean that it is turning over fast enough to start, this sounds like it could be one of two overall problems; One being a lack of fuel (or possibly too much fuel) getting to the combustion chambers, the other being a fault in the ignition system.

With a fuel system problem, possible culprits might be:

• empty fuel tank (don't just trust your gauge, physically check and make sure by adding some fuel or knocking on the tank).
• plugged fuel filter.
• plugged, pinched, or broken fuel lines.
• faulty fuel pump.
• no power to the fuel pump (wiring to the fuel pump is faulty).
• faulty fuel injectors, (although not likely all injectors at the same time).

With an ignition system problem, possible culprits might be:

• bad spark plugs.
• faulty spark plug wires.
• faulty ignition coil pack or ignition coils (depending on engine).
• faulty power or control wires to ignition coil.
• faulty wiring to fuel injectors.
• faulty engine computer.
