1991 Ford F-250 Problems
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 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.
1991 Ford F-250 Questions
This is a box truck which appears to be the same size as a FEDX truck. I am assuming its a 250
The oil pressure and battery volt meter gauge work fine. I was told that these gauges are all on the same fuse. The heater works fine so I don't think its a bad thermastate. Any advice would be very helpful Thank You

1991 Ford F-250 Recalls
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.
