No start condition in cold weather on 2006 Ford F-250 deisel

I will try to help. Plugging in your truck may set the P012f code in my opinion because this code is set when there is a 12 to 14 degree between antifreeze and oil temperature. However this is a problem under TSB 09-8-3 which recommends you replace the oil cooler, check the egr cooler and flush the cooling system which does not even address using a block heater. Concerns over burnt oil and oil overheating damage.

P341 is cam sensor, P460 and P463 pertain to fuel level sensors and having more fuel than tank should hold. Tank readings having excessive resistance and do not agree with other components. Suspect wiring or connections.

I will put in a comment about glowplug performance and using a block heater. While warming the block will do some good, the actual atomization of the diesel fuel is from the heat of the glowplugs and compression. Water temperature not so much.

The glowplug works on a series. The power module connects to the glowplug timer which regulates the pulses of power to the glowplugs. The duration of each pulse is affected by both outside and block temperature.

I check my glowplugs with a set of battery jumper cables. You put one cable fixed on the casing so as not to nick the threads of the glowplug. Then touch the other end to the top terminal of the glowplug. BE CAREFUL You can melt a glowplug or blow up a battery if you overdo it. Testing is a matter of comparision. Sometimes you can buy 1 new glowplug to see how it should look when hit with power and then see if the other glowplugs are much darker when hit with power. The dark glowplugs are worn or worn out.

Remember when you hear the timer cycle and the lights in the vehicle blink in unision. That is all the power your glowplugs are going to get. So if they do not glow quickly on your test, it will affect atomization of the fuel for starting.

Hope this helps, there may be glowplug testers that were invented after I retired.

Have a 2001 excursion 7.3 deisel shuts off while driving security comes on sometimes blinks othertimes it dont but wait to start light might stay on 15 min &other times two minutes

The glowplugs are the second element for a diesel to start. When the timer sends spark to the glowplugs they must warm up to atomize the fuel. Each glowplug must be removed to test and if you do not want to replace all of them you check them by using jumper cables and a 12v battery. You would put the negative cable clamp on the thread housing and briefly touch the positive on the plug top. This can melt the part so realize that it is a comparison of how long and bright the part will glow. A dark result, slow to glow, is a worn out part. You would remove at least 4 plugs for your comparison at a time. Also check battery health as these parts need maximum juice to glow.

Dodge 2006 caravan sxt 3.8L. Engine started running very sluggishly 2 weeks ago. Worse at low speed such as 0 - 10 mph. Cruising at 65 mph and then to say 5 mph in traffic causes engine to appear to "

Depending on the actual code for the O2 sensor, the fuel pressure may be low at times. You may want to look at fuel pressure and delivery.

This is not to hard to solve. The outside airtemp determines how long the Glowplug timer works for absolute cold starts. Starting a warm engine is affected by underhood temps.

The Timer Relay will pulse power to the glowplugs. If the glowplugs are good, it is enough to preheat the cylinder for firing.

To tell if a glowplug is good is a matter of comparision between a new glowplug and a worn glowplug. YOU CAN MELT A GLOWPLUG WITH THIS TEST, but you remove the glowplugs, get a set of battery jumper cables and place one jumper to the base of the glowplug USING CARE not to ruin the threads on the glowplug.

You do not want to arc the spark on the glowplug threads. You want your fixed jumper connector locked on the base of the glowplug. The other battery cable jumper is touched to the top of the glowplug where the arcing occurs. This will not hurt the contact point if done properly.

You compare the "glow" of the old glowplug to the "glow" of the new glowplug. Bad glowplugs stay dark or operate at a darker color.

The Timer Relay gives you pulses and that is all the glowplugs get to heat up. This is what you simulate in your test. If a glowplug operates in a dull or dark condition, it is bad and throw it away. You want all glowplugs to readily light up when power is applied.

The other 2 parts to the system are the Timer Relay and the Power Relay. The timer gets its power from the Power Relay and the Power Relay is like a starter solenoid. The Power relay gets a tickler charge when the keyswitch is held to Start.

There are sometimes extreme cold Timers that hold the power longer tothe glowplugs. I do not have the Specs to tell you if your Timer is kicking out to soon.

I hope my solution helps. I have told you how to test your glowplugs. The timers are affected by air temperature and that makes it difficult to say if it is working long enough. If you know the glowplugs are good, and the timer shuts off before the glowplugs heat up, then you need a new or different type of timer.

2005 f350 6L deisel shut off and wont run. will try to start on starting flued. fuel in fuel fillter is full can hear the pump.

You should check the Glowplug Timer. Most likely it is the Timer because the Diesels need the Glowplugs working to start. Then they fire from compression.

So even though the Starting Fluid reached the cylinders and the Fluid has a better Ignition point, it still needs hot Glowplugs.

You can check a few wires on the Glowplugs by using a voltmeter or Test light. Unplug each wire and then turn the key to On and observe if the Tester pulses a few times before your Ready Indicator goes out on the dash. If the Timer is not firing the Glowplug, test the power wire TO the timer. There should be a Relay for it.

You can jump the Power lead to the Timer and let the Timer heat the Glowplugs. Remove the jumper after the "Clicking" stops. Then repeat. Now hit it with a spray of Starting Fluid and see if she will run.

Then backtrack the Power wire to the Relay and see if the Relay is getting power. There could be a fusible link to the Relay that is burned out.

Would be interested to learn what you found. Autozone and Oreillys can sometimes pull up locations for the components they sell.

Glowplug light on my golf tdi

Hi Andy,
Remarkably, this problem is often associated with a faulty brake light switch down at the pedal!
It happened to my '97 Sharan the other day whilst driving along, and the merest tap on the brake pedal with my left foot stopped the glow plug light flashing.

Posh folk sometimes replace the switch; I would suggest checking the connecting wires down there first :-)

Hope this helps you a bit. If it does, a "Fixya" rating would be much appreciated. If it doesn't
help you, I'd be grateful if you didn't bother with a rating at present - they can't be increased later if I do manage to solve your problem! Just come back and tell me what you found. Cheers, D

Stalls and wont idle when cold

many automobiles behave that way on a cold start, so you don't have to worry about it. just continue to rev the engine until it is warm!
