Question about 1984 Ford F 250

1 Answer

Engine quits when it gets hot but starts when cold

I have a 1984 Ford F250 on propane. When it warms up it stalls then it won't start and it sounds like theres no spark. When it cools off it fires up right away. I changed the spark plugs and the ignition module to no avail. Any ideas?

Why it will not go into overdrive


It could take a better scanner to record this, but it can also be a temperature sender. Many Ford trucks lock out the overdrive until the engine warms up. They do this to prevent lugging and stalling. The truck simply does not know the engine is not cold anymore and the diagnostic system sees both cold and hot signals as normal.

Why wont my 2000 ford f250 diesel 7.3 start when it is cold?


Because it is a diesel engine. They use compression to push the air and fuel mixture together. It pushes them together under such high pressure that they heat up enough to spontaneously ignite. If the block is cold, the mixture won't get hot enough to ignite. If you don't have a block heater, you need to have one installed so that it'll start when cold. Your only other hope of getting it started, besides building a garage to keep it in, is to put a tarp over the hood and run a propane or kerosene heater under the engine until it is warm enough to start.

I have this problem for quite a bit. The idling speed when engine started cold is between 700-800 rpm. As the engine gets hotted idling rpm increase to almost 1000rpm. If idling is adjusted back, the rpm...


There appears to be a thermal movement of choke mechanism that comes about once vehicle is warmed up. Check the chock connections, hot water pipe and linkages tight or clear.

We think it is the diesel injection pump but not sure


Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day

1995 Ford F-250 replaced fuel filter and alternator, but the truck runs for a few miles then it stalls...or acts like it is out of fuel. it will not start until it has been setting for awhile


Sounds like fuel pump could be on it's way out. Obviously you don't have access to a fuel pressure tester for when it's a no start situation, so maybe try this. Grab a can of WD-40 & a screwdriver/nut driver, that will allow you to take intake hose off at throttle body inlet. Next time it quits, remove air intake hose, open throttle plate & spray WD-40 for a couple of seconds into throttle body. Try to start, if it does, for a second or 2, replace fuel pump. I believe what's happening is once the pump gets warm/hot, is quitting, then sitting, it cools down & pumps up to pressure again. This will confirm.
