Tip & How-To about 1997 Ford F350 Crew Cab

Easier starts in the cold temps.

If your getting hard or no starts in the winter/cold temps cycle the glow plugs 2-3 times. They are programmed to cycle up to 120 seconds or 2 minutes which in some cases isn't enough. Turn the key to ignition (not start) and allow the plugs to heat for about 90 seconds then back off again. Do this 2-3 times and your diesel should fire up. If extremely cold plug it in for an hour which should be enough to assist in starting.

toyota lucida hard to start most times. occasionaly ok. 2.2 diesel. everything seems to work as should


in cold weather diesel gels up and sometimes causes a no start issue..a cetane fuel additive helps with this issue. if temps go below 20 degrees, add a quart per tankful of cetane to the fuel to help start on cold mornings. also diesels require more amperage to crank than gas engines do..thus a stronger battery is needed..

trouble shooting procedure glow plugs '93 VW Golf 1.9 diesel


What you need to do is make sure the key is off, remove glow plugs, hook a set of jumper leads to your battry, put the negative lead around the threaded part of the plug, hold the + jumper lead to the top of the plug where the power rail bolts on. DO NOT TOUCH glow plugs as they will heat up hot & fast. If the light comes on 6 - 8 sec thats how long you need to hold the power on. The tip of the plug should be nice & red hot in this time. Repeat for all plugs & see the diffrence If more than 2 are dead (no red heat) or noticably slower than the others It will be very difficult to start & the plugs should be replaced. AGAIN carefull not to get burned.

05 c200 cdi preglow light goes off then soon as start driving comes back on for a couple of minutes then goes off


The ''glow plugs'' preheat for starting but also cycle off and on on a cold engine to help with more complete combustion before the engine reaches a certain temp. This usually takes more more often during winter but is norrnal if it goes off after a while.

my 2004 f250 after it sits it wont start. the wait to start light only comes on for bout1 to 2 sec. the only way i start it is to plug it up at night what is my problem.


The wait to start light always comes on for at least 1 sec, if it goes off early it must think the engine is warm.

My guess is you have a faulty engine oil temp sensor that is telling the pcm that it is already warm. The only way to know for sure is to read the info with a scan tool.

Glow Plug System: Description and Operation
GLOW PLUG SYSTEM
The 6.0L diesel engine uses a glow plug system that preheats air in the combustion chamber to improve cold engine starting.
The system consists of:
- glow plugs.
- glow plug control module.
- powertrain control module (PCM).
- engine oil temperature (EOT) sensor.
- barometric pressure sensor (BARO sensor).
The glow plug monitor system is part of the On-Board Diagnostics II (OBD II) System.
The glow plug system is electronically controlled by the powertrain control module. If the oil temperature is below 55°C (131°F) the powertrain
control module will energize the glow plugs immediately after the key is placed in the ON position. Then, depending on the readings from the engine
oil temperature (EOT) sensor and the barometric pressure (BARO) sensor, the powertrain control module determines how long the glow plugs will be
on.
The glow plugs are located in the cylinder heads, under the glow plug buss bar.
The glow plugs are self-regulating. If the engine oil temperature is above 55°C (131°F), the powertrain control module will bulb-check the WAIT TO
START lamp but not energize the glow plug relay.
The glow plug ON time varies from 0-120 seconds depending on battery voltage, engine oil temperature and barometric pressure.
The glow plug control monitor (GPCM) system is designed to find failed glow plugs or failed wiring in the glow plug system.

B 2500 diesel pickup hard start from cold


Hey mate,

I have a Mazda B2200 from 1985, which has the same R2 diesel motor, and I had this same problem, which was exacerbated by the cold of winter....even here in a mild Melbourne.

Each time you turn the ignition on, the QSS (Quick Start System) powers up the glow plugs for about three seconds. This recycles again about three times, then.....nothing. The QSS reckons that you ought to have the bugger running by now!

In my desperation, I located the cable to the four glow plugs, and ran a second wire from the battery (+) via a push-button switch which I installed on the dash. This is my glow-plug BOOST circuit.

Now, when I want to start from c-c-c-cold, I push the button (with the ignition on) for about ten or fifteen seconds, which gives the glow plugs a goodly time to heat up the combustion chamber, and when I hit the starter, she usually fires up with a rattle, and a cloud of grey exhaust smoke.

BINGO!

(Of course, once the motor has warmed up, there is no need to use this BOOST circuit, for the combustion chambers are already hot enough to detonate the injected fuel.)

Have a go at it, as I know that it works!

John.
