1990 Ford F-150 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1990 Ford F-150

The engine oil pan gasket can develop a leak. Leaking oil may accumulate on the exhaust system resulting in a burning smell. Replacing the gasket should correct this leak.

If there is a vibration or noise at highway speed, it could be from the frontdrive shaft and may require replacement of the double cardan joint. A double cardan joint is a type of driveshaft joint that uses two universal joints.

Tubes for the EGR system (exhaust gas recirculation) can break, causing an exhaust leak and noise under the hood.

Ford has extended the warranty coverage of the fuel pump and sending unit assembly in 1990-1993 F150, F250, and F350 trucks. In some trucks, the check valve may become damaged inside the fuel pump unit. This can cause fuel to travel from one tank to the other, creating an overflow condition. In the presence of an ignition source, a fuel leak may result in a fire. Dealers will repair the fuel pump and sending unit for up to 12 years or 150,000 miles from the original warranty start date.

THE IGNITION SWITCH COULD EXPERIENCE AN INTERNAL SHORT CIRCUIT.

Ford has recalled 1990-1993 F150, F250, and F350 trucks due to a faulty fuel pressure regulator and malfunctioning fuel pump check valves. Fuel may transfer from one tank to the second tank, causing a possible overflow condition and fire hazard. Dealers will replace the fuel pressure regulator and install redundant check valves.

I have the 5.0L with the long base and I really like. The fact that I can work on it is great, now adays just about everything requires the need of a computer and Im a hands on type of guy.

This is a great, solid truck. I have the 5.8 liter engine and it has 136000 miles and still runs strong as an ox. This has a solid suspension and steering, and have been on numerous off-road ventures and havent had a problem with it yet. It has great heating and the coldest air around. The only problem is due to the vents running on a vaccum system, it breaks easily and all i have is the defros...
