I would check out the heat and ac switches. They are notorious on older fords. May be available in aftermarket stores that sell the HELP products.

I JUST SPENT A WEEKEND SOLVING THE ISSUES THAT SEEM TO BE THE SAME AS YOURS. FIRST THE PROCESS OF THIS MODEL IS THAT WHEN THE KEY IS PUT IN THE RUN POSITION, THE FUEL PUMPS ACTIVATE AND ONLY FILL UP THEMSELVES. WHEN THE TRUCK ENGINE IS CRANKED, THE OIL PRESSURE ACTIVATES THE SENDING UNIT AND IT ACTUALLY TELLS THE FUEL PUMPS TO KEEP PUMPING WHILE THE ENGINE KEEPS TURNING OR RUNNING. IT IS A SAFETY ISSUE, AS IN A WRECK, THE ENGINE DIES, AND THEREFORE THE FUEL TO THE ENGINE IS STOPPED, AS A FIX, TRY PRIMING THE CARB, AND SEE IF IT RUNS BRIEFLY. YOU WILL ELIMINATE ALOT OF EXTERRANEOUS ELECTRICAL ISSUES IF IT RUNS. NEXT, CHECK CONTINUITY AT THE FUEL PUMP RELAY. IT IS LOCATED UNDER A PLASTIC COVER ON THE FIREWALL TO THE RIGHT OF THE BRAKE BOOSTER PUMP. MINE HAS 5 WIRES GOING TO IT. I HAD TO UNSCREW THE COVER TO ACCESS THE HIDDEN SNAP THAT HOLDS IT IN PLACE. HAVE SOMEONE CRANK THE ENGINE AND FEEL IF THE RELAY ENERGIZES. IF IT DOESN'T, AND THIS IS WHAT WAS WRONG WITH MINE, YOU WILL NEED TO FIND AND REPLACE THE OIL PRESSURE SENDING UNIT WITH 2 WIRES. THERE ARE 2 WIRES THAT WILL LEAD YOU TO THE OIL PRESSURE SENDING UNIT FROM THE RELAY. THERE ARE 2 SENDING UNITS AND THEY ARE LOCATED AT THE REAR OF THE EXHAUST MANIFOLD, BEHIND THE CARB. THERE IS A BIG ONE, WITH ONE WIRE, WHICH IS THE OIL PRESSURE SENDING UNIT FOR THE GUAGES, BUT BELOW THAT IS ANOTHER SMALLER SENDING UNIT THAT HAS 2 WIRES GOING TO IT. IT CLOSES WHEN THE ENGINE TURNS OVER AND ACTUALLY TELLS THE FUEL PUMPS TO KEEP PUMPING GAS. SEE IF THIS WORKS. THE FUEL PUMP RELAY WAS 15 DOLLARS AND THE OIL SENDING UNIT WAS 16. SPENDING ALL WEEKEND WITH THE WIRING SCHEMATICS AND TRACING ALL OF THAT STUFF-----------PRICELESS.

More them likely you have a vaccum leak, check vaccum line that gose into fire wall under hood make sure it has vaccum, if don't find vaccum hose and repair, if it does check vaccum hose under dash follow it make sure it's plug in, if it is could be a bad vaccum pull off or bend door or the selector switch. Good luck hope this was helpful.

On my F-250 it does the same but the great thing is that the hot/cold air is not hitting me in the face until it get the right temperature to come out of the vents.

Transmission


well if you can find one out of a f250 in the 80's wit a 460 the tranny should match an most of the trannys in the f250's have overdrive.
