1990 Ford F-250 Problems
RepairPal has identified the most common problems with the 1990 Ford F-250 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The Ford F-250, with the optional 5.0L/302ci V8, may develop misfires, rough running, and loss of power, accompanied by the check engine light illuminating.
Replacement of the ignition wires, and securing them away from the exhaust manifold is necessary to remedy the rough running conditions.
The tachometer sensor may fail; if the tachometer needle jumps around and the transmission has harsh shifts or does not upshift, this sensor should be checked. This sensor is mounted in a cover at the front of the motor.
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.
The battery light may illuminate on the instrument panel because the alternator wire harness connector is damaged. A new connector kit is available and should be installed to correct this concern.
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.
Any failure resulting in an over-rich (too much fuel) mixture can damage the catalytic converter. After a repair for the over-rich condition is made, it is recommended the engine oil and filter changed. When an engine runs too rich, the excess unburned fuel gets into the oil and contaminates it. Not changing the oil when it has been saturated with fuel can cause the over-rich condition to continue, making it appear the original problem was not corrected.
