20 Most Recent 1981 Ford F 150 Questions & Answers

If the transmission was rebuilt 2 years ago the fluid and filter did not need to be changed. In a 1981 there are no trouble codes to retrieve so whoever suggested that is out to lunch, Unfortunatley you need to get the transmission rebuilt again, hopefully it gets done better this time. Using the dexron oil in Ford transmissions is something transmission shops do because they don't want to stock different fluids. While it's not likely that using dexron oil lead to the failure it would be better to use mercon or type F oil.

The problem is that when you have the switch in the START position, you are getting power to the ignition system, but not when in the RUN position. Most likely causes are a bad ignition switch, a faulty aftermarket alarm system [if it has one] or a bad ballest resistor wire going to the ignition coil's + terminal. You need to break out your test light and start checking to see where the fault lies.

Check fuseable link wires(original ones have flags on them) that are on battery side of the starter solenoid.

You need a carburator adjustment. I'm guessing it is a 302cid? It's burning too lean

How much do you think a 2-door hatchback could handle when <a href="http://www.mikestowingandrepair.com/contact.html">towing in Mt Gilead</a>? I might have to tow a small trailer to the dump and I don't know anyone who'd let me borrow a bigger car.

Start with the battery. Make sure it is at a full state of charge, at least 12.6 volts on a voltmeter. If it is under 12 volts have it charged, or if battery is over 4 years old, best to replace it.

With a good battery, clean all battery connections. Get rid of all corrosion so you have a clean metal to metal contact. A solution of water and baking soda helps a lot. Replace questionable battery cables. Then get a good tight fit on all cables, battery, starter, and ground.

Now if you still have no power to anything, lights, or switch, horn, anything...then you will have to find the fusible links just off the battery that distribute power to the head light switch, to the key switch, to parts of the fuse panel, etc. If fusible links blow, they can be cut out and replaced. They act like fuses, designed to burn out to protect the rest of the circuit from burning up from a short or amperage surge from a shorted electric motor. Once you get power to the lights and the key switch, you should be good. Go from there.
