If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. The inertia switch is located on the firewall and can be tripped when the parking brake is set too hard and then released. The inertia switch should be reset, and will click when it is reset.

If the engine stalls when coming to a stop and/or has a rough idle, it may be due to sludge accumulation in the throttle body and idle air control valve. The throttle body and idle air control valve will need to be cleaned if there is buildup.
Failure to change the power steering fluid can cause the fluid to become gray with metal particles. The contaminated fluid can damage the power steering pump resulting in a growling noise when the wheel is turned; the damaged pump will require replacement to eliminate the noise.. Life of the power steering gearbox and pump will be shortened if the fluid is not serviced regularly.
The radius arm bushing may wear, causing a clunking or popping noise when driving over bumps. To repair, the bushings need to be replaced. Depending on the severity of the wear, the brackets may also need replacement. Driving with worn bushings will shorten tire life and cause tire cupping (uneven tire wear).

1991 Mazda Navajo Reviews
I have had 3 Mazda Navajo's , first one was great, but rusted out due to northern winter salt on roads. Second Mazda Navajo was a 2WD base model 5 speed that lasted 315K mi. 2nd Navajo major repairs were Clutch, fuel pump, ball joints, and cylinder head rebuild at 210K mi. 3rd Navajo is a 4x4 5spd rust free TX truck and low mileage, no major repairs but needs front ball joints in the near future. Things to watch out for as a owner front ball joints, fuel pumps rusting out (northern trucks), push rods (making tapping noise) and rubber plugs on back of 5 spd transmissions shift housing, they dry out rubber cracks leaking fluid until trans goes dry on fluid, to fix remove plugs clean with brake clean and reinstall them with Ultra grey. Automatic trans. are weak for towing and 4x4 axle u joints are a big money repair. Over all these are great trucks
