1990 Ford F-350 ProblemsFuel injection pump level sensor may fail
The FIPL (fuel injection pump lever) sensor may fail. When this sensor goes bad, shifting is erratic and the Check Engine Light should illuminate. Proper adjustment of this sensor (when replacing it) is a must or the problem will continue. See service manuals for proper adjustment of the FIPL sensor.
A ticking noise may develop from the engine due to a warped exhaust manifold. Damaged exhaust manifolds will require replacement to correct this issue.
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.

1990 Ford F-350 RecallsFord Extends Warranty Coverage for 1990-1993 F150-F350 Trucks Fuel Pump/Sender Assembly
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.
