Did you try changing the Fuel Filter?  That did it for my Kia Sorento 2004.

SOURCE: car wont rev

under the bonnet on the back of the mechanical pump there is a unit held in by 2 bolts
remove this unit and on the end there is a tiny filter
this will need cleaning because when the lift pump brakes down tiny parts of it get sucked up through the pipes and clog the filter
it may be best to feplace the fuel filter aswell

SOURCE: bmw 325tds diesel flowing back to tank when parked

usual problem ,valves in injector worn for the fuel pump.easy quick fix this one ,fit a non return valve in the inlet pipe,check flow direction on valve when fitting and evan better as well is another in the bleed off return pipe .valves available from a motor factor or a specialist garage like bosch or lucas ,cut pipe and fit the valve with a piece of rubber pipe to connect the valve in line.or listen to the people who want to milk the golden cow and have the whole injector pump overhauled .

simplest answer first,and this does not apply to a hot engine,The engine heaters work from a time switch on the door(would you believe)and the routine is, open door,climb in,put on belt,put key in ignition and turn on when orange light goes out.this allows the cold start heaters time to work(about 20 secs).sounds a pain but the number of times this has been all it is,when you put key in ignition, the fuel pump charges the system.hence the squirt noise,also the car has to reccognise the key(immobiliser system)also try using wynns/redexe to clean injectors...

SOURCE: display reading top up coolant, losing water but no signs of leak

Replace your overflow cap. You usually don't see it leaking but the cap no longer holds the psi and the water comes out and dries quickly from the heat. Try replacing the cap and I think you will be surprised at such a simple problem can cause.

I need a diagram to show me the routing of the petrol pipes on a citroen c3 from the petrol tank to the engine and back to the petrol tank please?


the fuel is constantly rotating round the fuel lines, the fuel is pressurized, so any fuel that is not used by the injectors is sent back to the tank.. this give a constant flow and pressure to the tank. the pressure in the tank is regulated by the pressure relay that lets air into the tank to lower the pressure. this is regulated by the ecu and your speed. if the pressure drops or is to high in the tank the engine can cut out on the fuel rail there is a fuel pressure regulator this keeps pressure on the fuel line coming into the injection system. some systems have duel line feeds from the tank for 2 rail systems, this system was not reliable due to the amount of feed pressure needed to fuel 2 lines. and can cause pressure leaks. some systems have a pressure regulator controlled by the ecu on the return line, this is more fuel efficient as it keeps the fuel at a steadier flow back to the tank and give a better fuel spray into the engine. hope this help you.

206 hdi looses power for second then is ok this only happens now and again


I also have a Peugeot 206 HDI and have had power drops on 2 occasions.
1st time caused by loose catalyst in exhaust... it was bouncing about so that it's honeycomb holes would align one minute, then drift out of line another minute.... sometimes really strangling power as it nearly blocked the exhaust..... I realised it was the catalyst after noticing it got really hot whilst the following exhaust remained cold as struggling up a hill.To check for this you can slacken the turbo to catalyst clamp so exhaust can escape .... and power should go back to full.(you can drive a short distance on open turbo without real problems... plus it quietens the exhaust reasonably enough)
2nd time was air getting into the diesel line ..... small bubbles would get sucked in whilst parked, due to fuel draining back to tank, and sucking on a loose fuel line joint on the squeezy priming bulb pipe.This caused short power dips initially but worsened over 6 weeks until the diesel filter would collect a pocket of air whilst parked.... causing it to completely stall a short while after starting..... Usually during acceleration, the fuel surge pulling the bubble through.
..... fixes .... 1st, I cut open and removed the catalyst, and re-welded casing shut (not needed in UK diesel test) and breathes better now :0) 2nd ..... done today, replaced bad pipe with high pressure fuel line and good pipe clamps. I've ordered a non return valve for the fuel line too (not that it needs it now) ..... to stop so much air getting in if it happens again, as I guess this is pretty bad for the high pressure pump, and a pain to replace if it goes ..... .... Beware of the very high fuel line pressures after the pump in running HDI engine.
The air mass sensor can be unplugged to test ... the engine will still run normally if no other problems.

1995 chevy tahoe 4wd. 5.7 liter when cooled down, starting is normal . Right after, engine almost stalls but Idle air control kicks in and keeps it running. eventually it is idling but rouph. On...


If your vehicle has one, and I think it does, check your EGR system. If the egr valve is full of carbon, it can be partially open, creating a vacuum leak. If the egr valve solenoid is bad, it could be opening the valve at the wrong time, also creating a vacuum leak. Unplug the egr vacuum hose, plug the open end of the hose and start it and see what it does. A picture of the egr is below.

My 1993 mercury tracer has a fuel leak


first locate approx area of leak, wet spot, smell. fuel lines run from top of tank in rear of vehicle to the front usually alomg the inside frame rail on drivers side and up into engine compartment (under the hood) to the back of the motor. it runs into fuel rail assy where the injectors are passing through a fuel regulator first. fuel line will have a valve similar to that on a bicycle or car tire and should have a tag on it, sometimes its on the fuel rail. trace the fuel line tu the fuel tank or from the tank to engine compartment while its running, in park with emergency/parking brake on to accurately locate leak but be careful for fuel that may be spraying. i recomend safety glasses and a flashlight. most common leaks are due to worn/bad seals in the "quick connect" connections or a crack it the line itself.

Citroen dispatch 2.0 hdi suging and lacks power unless highly rev'd but NO black smoke at all


look under and around the iar filter /engine cover for a sensor with a vacumn pipe attached ,think thats the renault but i just cannot remember but it causes this fault ,failing which check the fuel filter for sucking in air by pressuring the system with a electric pump and looking for leaks connect to pipe from fuel tank and outlet to where the pipe connects and then run pump to look for leaks ,the fuel filter is at the front of the engine ,then if no leaks check the reading on the mass air flow sensor ,a OBDII cheap code reader will do this by checking all the pids it will show timing and air temp ect and this vehicle can be read with one depending on year

Gas gage says empty,when it is half full.Why wont car start


The incline is apparently enough to have the feed from your tank exposed to air and not gas. If you can let the vehicle roll back and turn the wheel so your facing in the opposite direction before you attempt to start it again. This will allow the fuel to feed out of the tank like it is supposed to and should start fairly easily. Since the line is empty now, it make take a few seconds more than usual to prime with fuel and crank. Parking on inclines will get you if they're steep and your tank isn't full. Just remember this and next go round if you have to do this again, make sure your vehicle is parked in the opposite direction and the feed tube out of the tank will still be covered with gas.

I backed my 1997 explorer into a slightly inclined parking space and left it running when I returned it had shutdown and the check gauges light was on and it will not restart.


If the incline is steep enough, you may have had enough angle on the tank to allow air into the fuel line and it will act like you are out of gas. Try coasting off the incline and starting on flat ground.

Citroen picasso keeps cutting out twice a week on acceleration


Sounds like an air leak or the tank pump cannot keep up with demand (the supply pump in tanks do give trouble (a pressure gauge between tank and engine would tell, make sure it is visable when driving, I used to tape it to the bonnet with masking tape.
