Sounds like either a leaky fuel regulator, or fuel injectors.

run the fault codes and look for a venting problem in the tank
your description suggests that there is a vacuum forming in the tank and causing a fuel starvation.If it has a vent valve on top of the tank check that it is not blocked

Why would my 1995 toyota corolla be smelling like gas very strongly?


I would be considering if the fuel cap is pressurised, if it is then the charkhole canister breather my be blocked . but if it doent start straight away then u must be loosing pressure in the fuel system,does it make a difference how much fuel is in the tank ?it can be the fuel over flow pipe if you fill the tank right up and park it the fuel can swell, it exspands. I hope this is of some help. if not I would like to know were you park it ,how much fuel is in it , is the swell strong inside the car or under the bonnet , in the garage

Isuzu kb 280 dt got a fuel starvation problem after it stands for a few days, when i pump the prime pump on top of fuel filter the problem is gon.


It could either be a fuel pipe between your prime pump and injector pump that sucks air so your diesel flows back into your fuel tank. Or you need to replace the prime pump.There is a rubber diaphragm in the prime pump that gets worn. Unfortunately need to buy a new prime pump. A simple sollution is to fit a non return valve to your fuel line. That need to be connected between the prime pump and fuel tank. Hope it helps. Blessings

I have a SSangyong musso 1997 with a 320E motor, my problem is a fuel one. erratic idle and fuel starvation on up hills or when driving long time on open road


Most of the time it is caused by the little "O" ring which is located in the fuel pump. They dry out and get a crack in them. Take the fuel pump assembly out of the fuel tank which is located under the rear left passengers seat and replace the "O" ring. All fixed. If need any more info, look at the SsangYong Owners Club of Australia forum site at http://www.ssangyongownersclubofaustralia.org/website

All the best..

Diesel 1989 F-250 set too long and will roll over


You may have to bleed the fuel system. There may be a very small air leak in the fuel supply line and after a long time idle, the fuel seeps bac into the tank, leaving an air lock in the pipe. When you go to start, this air makes its way into your injection pump & needs to be bled out before the engine will start. Begin from your fuel filter bleed valve, next the injection pump using the primer pump to transfer the fuel. Next loosen off the injector pipes and crank the engine over until fuel sprays form all the joints. Tighten injector pipes and start. It may run a bit rough for to begin with, but will soon even out. If it doesn't start, repeat bleeding of injectors.

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 .

Strong Diesel Smell inside HJ Turbo Diesel Landcruiser


Since you didnt notice any change in the performance of your engine, ill presume there's nothing wrong with your fuel injectors.
look for moisture around your gas tank cap, the hose and clamps going down the tank, around the fuel gauge sending unit of your tank. have your fuel line checked from the tank to your fuel injection pump, give particular importance around the connections of your fuel filter, fuel pump, and the return hose from your fuel injection going back to your tank.
Diesel do emit strong hazardous odors that may stick on carpets inside your car.
