My car will only start when I put more fuel into the fuel filter when stopped. I will have to then turn the key for at least a minute whilst pumping the pedal to get her to go, keep her in high revs then drive. Once she is running, she's generally ok, I take her for a 30minute drive, no problem, leave her idiling, fine. As soon as I switch the engine off for a lengh of time, same problem comes back. It was intermittent many months ago, it went away & now it's came back every time now. Has anyone else got any experience on this topic?
Well, first of all, it would be really nice to know what kind of vehicle we are talking about. YEAR, MAKE, MODEL and ENGINE SIZE / TYPE is usually customary for this type of discussion.
What is particularly disturbing is the question of: How are you going about "put[ting] more fuel into the fuel filter"?
Testimonial: "Thanks for the info.. That totally makes sense. Albeit, i'm a bit worried now, as i have to run the car for probably for another week before getting the part(no public transport in this area)! Shit!"
Carl's solution might work OK for a gas engine, but it doesn't exactly apply to your TDi engine, although some of the principles are the same. There is a check valve in the fuel pump module in the tank that is supposed to hold a small amount of pressure on your low side fuel supply to the injector pump. It sounds like what is going on is that this check valve is bad and is allowing the fuel to drain back into the tank after the engine is shut off. If it is siphoning the fuel from the fuel filter, then the injector pump will not have enough fuel to get the injectors working. This can turn into a serious problem because the injector pump is actually lubricated by the diesel fuel. Every time it does this, you are operating your injector pump without any lubrication...it is like repeatedly running the fuel tank empty....serious damage can occur if it is not promptly fixed.
You will most likely need to replace the lift pump assembly in the fuel tank.

If a fuel pump is going bad, you will have a noisy pump, stalling or engine will not start. lack of fuel pressure to injectors. .but as you said if you prime the system it runs ok until it sits for awhile. this indicates the fuel pump is working or has low pressure buildup in fuel lines. check for a bad fuel pressure regulator, it should be mounted on engine by or at the fuel rail. most regulators have a vacuum line to them. pull this line off while engine is running and if there is signs of fuel in hose or regulator it is bad. the regulator keeps constant pressure at the fuel injectors will work properly. good-day ! check the fuel filter for clogging up.

HI...
The common cause of the problem that you related.
Is the FUEL PUMP RELAY " Called MAIN RELAY.
Is located : left side under the dash.
Is a BIG relay gray colour. with a connector of 7 or 8 wires.
I recomend replace the relay.
And letme know if you solve your problem.
I hope this information work on your problem.
Thank you for use fixya.

i gaurantee that it is the fuel pump ressistor up on the passenger side front behind head lamp assembly you will find the connector with two wires going to it. no need to remove old one install new one and connect wires to new one leave old in. dealer only part but not expensive. dont belive dealer when they try to talk you out of it. This is a kit to relocate a ressistor that has been installed in a poor location. I promise this will fix it. My wifes car did the same thing, took 20 minutes to fix and that is only because i am an electrician and am finicky about where to locate wires etc. the kit comes with installation instructions however they are a little vague. trust me. easy fix. my dealer tried to get me to leave car for repair and said it sounds like the theft detterent system. they were wrong and i was right. dont trust em

hi i am dieter

here is something to try
keep some cold water with you and the next time it happens very quickly get out and pour the water on the crankshaft sensor then restart. If it starts right away without the usual two minutes than you will need to change this sensor. The sensor is easy to find you will see a wiring harness around the crankshaft pulley(the large one at the bottom the basically runs all your accessories like the p/s pump, alternator, water pump). Try to famaliarize yourself as to the location of the sensor first so that you can try to restart it within about 30 seconds.

I have a 1990 ford f-150 whent to start it and nothing No fuel pump hum nothing I replced fuel filter and 2 relays and fuel safety not popped up all the engine does is crank over and thats it.
SOURCE: 1995 Toyota camry Le 4C Missing Problem -
i have came across simler problems in the past so im going to give you a list of four main suspects number 1; a broken or pereshed vacuum hose at the trottle body or inlet manifold.2 a blocked injector 3 a fuel injection system fault 4 a disconnected /leaking or perished crankcase ventilation hose.Before you try any of these by a can of fuel cleaner and run it through your system remember a small piece of dirt half the size of grain of salt is enough to cause this problem good luck.adrian

What is the make, model and year?
Sorry dttech, I thought make & model were on the heading.. Volkswagen Bora 2003.. 1.9tdi SE 130..... Roughly 135,000 on the clock.... The fuel filter has a return pipe into it that is sealed with a rubber grommit, easily removed, & when the car is running I can lift it up & fuel is coming out of it, into the filter..
