Question about 1984 Ford F 250

Idleling of 1984 F250 Ford PU

I have a 1984 Ford F250 pick up truck with a 5.8L engine. my problem with this truck is that when I start her up I have to keep my foot on the gas, otherwise she will not idle and shuts off. i notice that it has a carburator solenoid with a vacuum hose attached. i also noticed a loose blue wire but don't know where it goes. Does the carburator solenoid work strickly with vacuum or does it need electric to function. Is there a diagram of this carburator available online to download and compare or am I aiming at the wrong solution?

    same problem on my 85 f250. Device on side of carb seens to be sticky or broken- is this the automatic choke? Is it easily changed out? I could use a vacuum line diagram too

Mcdevito75, That carb, solonoid most likely works with both, electricity and vacum, That blue wire should hook up to that solonoid, look at the plug ans solonoid and see if there"s a point for the wire. If it has broken off yo"ll have to replace the solonoid. Also have the choke system on your truck checked out, if the choke is not operateing as it should this too can cause your problem. Have your local repair shop take a look.

Ford is common for the inertial safety cut off to trip. It is usually in the trunk on a car, but I don't know on a PU.
There is a relay box with a small pin to push back down.

The engine will shut down and will start again up to 15 min. later every thing will function the anti theft light will blink and the starter will turn the engine over. never know when it will do it. I...


Seems heat related so first thing to change would be the coolant sensor in the thermostat housing. This tells the ECU whether the engine is hot or cold. If faulty after 10 - 15 minutes it could over fuel and cut the engine not allowing it to start until it has cooled back down.

1996 ford f250 truck 4x4 5 speed 460 will not start.duel tanks-was running,tank one empty-switch to tank two-engine died-won't start.


Running tank one empty could have picked up **** from the bottom of the tank and clogged the in line filter that feeds the engine. It should be located under the truck on the left inner frame rail around the back of the cab area. Replace it don't try to clean it out it will just clog again. They are not that expensive from the locale parts house. DHR... EX Ford Line Mech
