Question about 1996 Ford F250 Crew Cab

1 Answer

No cold start

1999 F-250, oct,1998 build date7.3 litre will not start if outside temp is under 45 degrees or so, it will start however if i plug it in for about two hours depending on how cold it is outside. I have checked glow plug resistance and actually had to change 3 of them,and yes the relay is working correctly. I have changed crank position sensor, cooloant temp sensor, engine oil temp sensor, high pressure oil pressure sensor (regulator), and the thermostat. The fuel heater is good but I dont know if it is turning on, I do keep fresh oil and filters in the engine and just recently replaced both batteries, it cranks good starts good and runs good when its warm. It has 165000 miles But was rebuilt by ford dealer at 85000 miles under warranty due to low compression in two cylinders caused from what they called dusting (very fine dirt passing through air filter). They also replaced the turbo and the injectors in the same two cylinders. I do suspect another injector going bad because it does smoke and idles rough on start up unless it has already been warmed up or has been plugged in for a long time (over night). It has developed an exhaust leak right after the turbo but the cold starting problem existed long before the leak. IT JUST WONT START COLD, warm runs great

I have a 2006 audi a4 3.0 when temperature outside drops below 40 degrees it will not start ,when the temperature outside gets around 45 degrees it starts and runs with no problem . screen reads ok


I assume from the question that the engine is cranking over but will not start. Hence there is no issue with the starter motor on a very cold start.

At 40 degrees F you are getting closer to freezing. When this happens again I would check the operation of the fuel pump.
Take the fuel cap off the fuel tank and have someone switch the ignition on and off a few times. (just the ignition - don't start the engine up). Turn it on for 10 seconds or so and then off. If you listen at the fuel filler opening with the cap off you will be able to hear if the fuel pump starts and stops. If it is working it should start and then stop a few seconds later each time you switch on the ignition because the computer shuts it down in a few seconds if the engine is not started.

If the fuel pump is operating I would be looking for some electrical gremlins. You would need to check that the fuel injectors are getting power and that the spark plugs are also.

Ideally you would need to a quality scan tool connected to the car when you have this very cold no start condition whilst trying to start the car to see what faults may be present because it should pick up some malfunction if the start problem goes away when the temp rises a few degrees over 40F.

Engines cranks will not start


how cold
ever do a tune up,,
good spark plugs work way better cold. new ones.
as does fresh winter fuel.

Cold weather starting problem


I would say it's bad contacts in the ignition switch. Metals change dimensions depending on temperature, looks like 45 degrees is the trick point for whatever is in there. My 04 Silverado 5.3 with 196,000 has the ticking, but it is gone within 10-15 seconds.

98 BUICK REGAL GS AC compressor will not come on. It has the climate control unit. All the lights and fans work and there is enought freon. The display reads -38 degrees for the outside temp. Would this...


If the outside temp.sensor is reading -38 degrees then this is what is causing the compressor not to come on.You need to check the wiring to the outside temp.sensor and the sensor.Make sure it is connected.It is located on the front grill area.Between the grill and the bumper cover.Hope this helps.Good luck.

Chevy Suburban 1997 1500 won't start when Cold


it could be a tune up issue such as plug wires plugs . but my guess is its a computer engine temp sensor if it reads 5 degrees out of range it cuold give you a hard start or a no start problems the best way to look at this problem is with a scan tool when it is cold to see if the temp matches outside ambeint air temp 1 or 2 degrees ok b ut not 4 to five there is a nother way to check it buy useing dvom at a temp to omhs chart.

Misreading outside temperature sensor on 2001 Audi A4


There are four sensors for ambient tempurature and they work in unison to provide information to the temp reading on the dash, the heater control head ( where to direct air, blending of warm/cold/outside/inside air flapper controls) depending on the ambient temp and the inside air temp sensor located just above the radio as well as the sun sensor on the top of the dash as well as the a/c compressor head.

When you start your car, the body control module takes the readings from all sensors, outside air temp located in front of the radiator, air temp sensor located in the airbox ( senses temp of air being drawn in from the outside into the air box), coolant temp, inside air temp sensor and the sun sensor on top of the dash (this is why it takes a few seconds for the climate control system to begine when you start the car). The intake air sensor is 1st priority, inside air second, coolant third, ambient 4th and sun 5th. For instance, if the sun sensor reads the sun is hot but the interior sensor reads cold, the inside akes priority. The goal is for the system to achieve a tempurature inside the car that matches the selected temp. It uses all of the sensors to set the system up to achieve that goal as quickly as possible.

Example; Its mid afternoon, sunny and 40 degrees outside adn your in stop and go traffic. The intake sensor reads 40 degrees, the outside sensor reads 60 degrees (heat from radiator...engine heat protrudes into cabin) and the sun sensor reads high (sun is strong). The system is set for 72. priority one sensor reads 40, inside sensor reads 65, ambient reads 60= system will blow hot air to the floor out put, dash outlets will lightly flow 65 degree air so the sun doesnt roast you yet your feet are cold(if it blew hot air from all outlets, your upper body would be hot but your legs/feet would be cold). as the interior sensor reaches desired temp, air will be distrubuted through thee dash, defrost and floor with the warmest air coming out the floor and defrost, coolest air out the dash vents. Its a complex system!

The two sensors that will screw the system up the most are the intake and interior sensors. the system will function reasonably well with just those two sensors though it wont blend air temps between outlets if the sun sensor isnt working. If the outside sensor fails, it simply uses the intake sensor, if the intake sensor fails it will rely on the front sensor. However, since the intake takes priority over the outside sensor, if the intake sensor sends incorrect resistance info rather than failing, it will take priority and cause the unit to malfunction such as in your case.

The intake air sensor can be changed from the outside with patience. If it where me, I would pay the two hrs labor and let the dealer do it right.

1998 chevy S 10 won't start in cold weather. starts just fine when around 25 degrees or so. looking into cold start valve and thermo time switch, but don't know location of either, or how to check.


a coolant temp sensor will cause this problem if it is reading warmer than it is outside this will give lean condition .the sensor is located by the t-stat follow upper radiator hose down to housing.the sensor has two wires. thanks for your question.
