Have the fault codes read. Replace faulty items. Use only genuine items as non-genuine replacement are not always compatible with the OEM fitted CPU units. Look for position sensor with intermittent fault. Check all wire connectors for loose or dirty.

Fuel tank selector solenoid on a 1988 ford ranger. It wont select between the two tanks. Am i supposed to have voltage at the switch in the cab or does it originate from the solenoid?


The switch in the cab may be a ground. If you can trace the wire to the solenoid looks for power coming out wire color and see if they match to the tank.

Of course check all fuses and wires. Did you pull a wire lose driving over debris?

Also check the hose to the tank from the switch.
Removing the switch and testing it away from the fuel is safest.
With that many years on the truck I suspect switch failure.

Good luck with it - let me know any progress.

Fuel Problem


fuel pressure regulator? This diverts excess pressure from the rail back to the tank. When they wear out they usually stay stuck open thus diverting all pressure back to the tank. Pressure tests do not reveal this as pressure is checked before the rail not in it. I do believe you have a bad fuel regulator. They are 75US ouch.

Engine misfire, only when it snows


Have you or the dealers checked the plug wires? Often when there is high humidty weak plug wires can cause the engine to miss and this is difficult to diagnose in a shop environment. Modern ignition systems have very high voltage and also worn plugs can cause the voltage to spike. This would let the weak plug wires lose the voltage and cause the engine to miss.
