P38 diesel fuel injector pump overheats and inhibits starting

After a long run the heat build up in the engine bay means the diesel fuel injector pump gets hot and inhibits starting. As soon as the engine bay temp drops, it starts easily. This can be Accelerated by pouring cool water on the pump.

This is an unusual problem as injector pumps use diesel to lubricate internally and to cool the pump. For it to overheat and cause you problems means that fuel is escaping under high pressure or the operating pressure is excessive . Best discuss this with a professional diesel pump repair shop as I feel there is a serious problem in the pump.

Have a 1986 golf diesel it ran out of diesel and I

Are you certain that you put diesel fuel in the car? Had to ask that question. How long did the car sit before you refueled? If it sat for a while and if the temperatures and humidity were enough to produce a build up of water vapor, that might keep the injectors from sending "dry" fuel to the cylinders.

Just running out of fuel won't harm the glow plugs (hence poor starting) and won't require need for a new battery unless the current battery was failing even before draining the tank.

VW Jetta vdi diesel won't start after eun out of fuel

There will be 2 reasons. Either the very low level in the tank allowed the pump to pick up some of the sludge that generally accumulates. This would mean a strip down and clean. The other is that you have developed an air lock. This is easier to cure but potentially a bit dangerous to health!! Where the fuel lines feed the injectors, loosen the nuts off, just a bit, to allow any air out. Put new fuel in and try and start the car. DON'T stand near the engine bay as the pressure it comes out of those lines can inject fuel through the skin!! Crank engine until you see fuel escaping on in engine bay. Tighten them up and try and start car properly. If it starts then turn it off and allow discharged fuel to evaporate. After this if it starts but runs "lumpy" chances are still have an airlock in one of the feeds to injectors. DO NOT DO THIS WITH A WARM ENGINE. Be careful of the fuel, at all times

Diesel fuel injector pump overheats

take the vehicle to an accredited diesel repair specialist as there may be a relief valve problem or imminent pump failure. Discuss the problem with them. Make sure that the specialist is accredited in your pump as this is the best protection you are likely to get.

My 2002 chev. diesel truck turns over but wont start, new filter

anytime you change the filter in a diesel you have to bleed the air out of the fuel system. The pump won't auto bleed the fuel system for you. every place in the fuel system that has a flare type connection needs to be bleed, start at the connection closest to the tank, loosen the connection and then crank the engine until you see diesel fuel drips from that connection. Tighten the connection while the engine is still cranking. Move to the next connection that is going toward the engine. Continue on in that manner toward the engine until you reach the injector pump/injector. Once you reach the injector pump be VERY aware that the fuel is at VERY high pressure. Do NOT put your body parts in the stream of high pressure diesel fuel. It could kill or injure you! Once you bleed all the way to the injector pump/ injector, the truck SHOULD start. Do not bleed after the injector pump because of the pressure involved, it is WAY too dangerous.

Good luck!

How do you prime diesel engine when run out of fuel 04 6.0

Ned. I don't know much about those 6.0's but in general the procedure is the same for bleeding. Make sure the filter is full before you start. There is an electric fuel shut-off switch on the injector pump that needs to be disabled next, usually by disconnecting the wire going to it. If it has a fuse so much the better, just pull it. Loosen the fuel line gong into the injector pump and crank the engine. Do it in short 20 second or so bursts or you will overheat the starter and have to replace it. once the fuel runs clear from the pump, no bubbles then you should be able to reconnect the shut-off wire. The engine should start and run rough for a minute or two but smoth out with-in that time. If it doesn't, you will have to loosen each individual line at each injector to bleed out the air. It should only take about 1/2 turn to get them loose enough. Do the injectors one at a time with the engine running. Hope this helps.

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.

Running fine, then blew lots of white smoke that smelled like diesel, cut off and won't start again. Dee

If this is a gas engine You have probably blown a head gasket. If its a diesel engine of later years 03 or later you probably have an injector failure and or a injector pump failure. I hope this helps.
Thank You,
Roy
