    I have a 1991 Jetta 1.6 Diesel. Starts really hard. Air bubbles in the return line. When I ran a line from the pump to a bucket of fuel it would barely lift the fuel above the pump. In the last week the engine sounds like the timing has changed and noticebly less power.

MY 94 rodeo 2.8lt turbo diesel blows lots of smoke when the throttle is down.. When i lift the foot of it stops smoking.. can you help..

if its black smoke and id say it is being a deisel it can be injectors or just simply fuel pump timing. get it to a deisel specialist to check the pump timing and your fuel load under acceleration, only real way to get it sorted.

My vw 1.6 turbo deisel destroys turbos please help

Check the intake pipes from the air filter to the intake on turbo in case its got a air leak and its sucking in dust and grit ,If i knew what was being damaged in the turbo i would have a better idea ,if its the bearing then it has problem with the oil feed being partialy blocked with gunge from lack of oil changes which is the normal reason

No fire

check cold start injector relay and injector. are u sure that fuel pump is good? can u hear it come on when key is turn to on ? it should come on for about a second if yes check for fuel from injectors , pull one injector put from head point into glass jar remove rubber boot from air flow sensor assembly, pull fuel pump relay and install jumper so fuel pump contiously runs then using a magnet pull up on air flow sensor fuel should be coming out of injector in a cone shape.

Lack of power

Buy an FSE valve you will get about 15-20% more power. Don't play with the turbo it will just break. If you wind the pump up look out for smoke from unburnt fuel and wind it back until it stops.

Ford focus 1.8 turbo deisel 1999.

do not understand you what you mean. assuming your car was ok before you changed f/filter you need to bleed the fuel system of air. esiest to do would be to loosen fuel line at the injectors and have assistant crank the engine while you observe for clear fuel leak without any air bubbles from fuel line.tighten fuel lines and start engine. might have to repeat a few times. good luck.
