To check the glow plugs you can use a scanner (snap-on) or you have to take the valve covers off,take a test light n hook it up to your positive post on battery,pull wire off glow plug,take test light to glow plug if it lights its good if it doesnt the plugs bad,as for the fuel leak it may be the lift pump in the valley or it can also be the vacum switch on the fuel filter housing

I have a mercedes sprinter 313cdi van 03 model turbo diesel what parts on top of motor need to be removed so i can change the glow plugs

Shouldn't have to remove much to get at them. Does the glow plug lamp flash after the engine has started. I'm not sold on it being a glow plug issue, these engines start without them down to well below freezing without any real trouble, if it IS this its more likely to be a wiring issues rather than sudden failure of 4 glow plugs. Leak off pipes on the low pressure side, or an injection problem is more likely.

Starting issue, I have a 1993 ford f250 7.3l pre powerstroke. I started the motor and it stalled out like there was a short, now when i turn the key my glow plugs do not fire and wait to start doesnt show...

On some Models the glow plug Relay does not have an integrated Power Relay. This means there is a second Relay before the glow plug Relay that feeds it power.

You should check the wires running to the glow plug Relay for power with the key ON. Check some other wires off of the Ignition switch to make sure your 20 year old Ignition switch is good.

There are some sites which show vehicle wiring. Autozone has a free section after Registering your vehicle but it takes a little sorting through the Help section. There should be a fuse to protect the above Relays.

Make sure you find the Diesel-equipped wiring circuit. Diesel ignitions are different from gas units.

According to my Haynes Diesel Engine Repair manual this is a list of possible causes.
1.Slow idle incorrectly adjusted
2.Fast idle is inoperative
3.Restricted fuel return system
4.Glow plugs turn off too soon
5.Insufficient fuel suuply to injector pump
6.Injector pump malfunction
7.Incorrect, contaminated or poor quality fuel
8.Air in fuel.
The manual is part number 10330 anywhere they sell Haynes manuals ($20). It has a very good section on the 7.3 especially if you don't want to spend money at a diesel shop every time it needs work. Hope this helps.

Ford F-350 7.3L Powerstroke Diesel very hard to start when cold.

have you ever replaced the glow plugs on your truck.this would be the first place to start with a cold start problem.the next thing would be a fuel pump problem to check.

The Powerstroke motor has a few things that can make it hard to start. trying to diagnose it over the internet can be a daunting task. I would go to "the Diesel stop" on the internet, they are a forum dedicated to just Ford Diesel trucks. If you register (free) there is a section for your year. I am a member there along with over 100,000 members and you will probably get the answer you need there.

I have vw type 25 diesel 1600 cc .it takes ages to start the fuel seems to **** back into the tank so ive got to keep trying to start the engine till the fuel gets ther

I would try changing your fuel filter. Inspect the fuel lines for leaks. Air getting in the line would cause fuel to flow back into the tank.
I really suspect that the long cranking time may be a problem not with the fuel system but with the glow plugs, You probably need to replace the plugs as they are not pre-heating the combustion chamber properly to allow ignition of the diesel fuel. To start a diesel motor with out glow plugs you have to crank the motor until enough heat is generated to ignite the fuel. Glow plugs are not very expensive and fairly easy to change your self.

Slugish start on my excursion

Glow plugs do not "fire". You may be confusing the function of glow plugs as analagous to spark plugs in a gasoline engine; the purpose of glow plugs is to heat the air-fuel mixture to a temperature that will support the diesel auto-combustion process. The diesel process is not one in which the air-fuel mixture is ignited via spark like a gas engine; rather, the air-fuel mixture undergoes much higher compression and spontaneously explodes, generating the combustion in a self-sustaining manner. High compression produces much higher heat, but before it can begin, heat must be introduced into the system to get it started.

If you're having sluggish engine performance from your diesel engine, you may have fuel system issues such as fuel pump failure or fuel line restrictions (including fuel filter or strainer clogging), etc. At the "worst" end of the spectrum, one of more of your fuel injectors may have a problem - the fuel injectors on the Powerstrokes not only inject the fuel into the combustion chamber, but are also cooled and lubricated by the fuel - if the vehicle has ever been run out of fuel, the injectors may have been damaged and will need to be inspected for replacement.

04 f250 diesel cranks but won't start

this is an oil pressure problem, either a sensor is not sensing enough oil pressure, or the high pressure pump is not building enough pressure(possibly leaking or head is leaking). this engine requires 450 psi minimum oil pressure at the injectors to actuate the injectors.

95 powerstroke will not start

Check you IAC Idle air control valve, check your EGR valve. If both check out ok. Then make sure that the glow plugs are glowing properly if this is diesel, if this is gas check altornator and spark plugs.
