SOURCE: my 2002 VW Jetta tdi , wont start.Fuel shut off

The first thing to check is the intake cutoff valve. It's similar to a throttle body, but is usually fully open until the engine is shut off, then it closes fully to minimize engine shudder.
Sometimes carbon will build up in the bore where it sits, and after it closes it will not reopen.
It's the first part of the intake after the plastic tube from the maf sensor/air filter housing.
You can pretty much just put your hand on it and push around a little bit, and the spring will return it to the open position. It has an arm sticking out that is actuated by a vacuum solenoid.
I thought of this because you said it would not accelerate, and carbon also builds up inside the intake manifold, reducing airflow so much that it can't get enough to accelerate.

This is assuming that you've got a situation where the engine is cranking, but not starting.

Let me know if this helps or if you have more questions. They often have problems with the glow plug circuit, but this should set a trouble code.

2005 vw polo 1.9 tdi wont start


if it starts when you pour fuel in the intake.. then fuel is not reaching the tbi from the tank..you say you put a new fuel pump on this..did you bleed the fuel lines? if not do this because there is an airlock in those lines..either you need to open a fuel line at the tbi unit to bleed it all out.. or be looking at a clogged up fuel filter..

Citroen 2.5 hdi i have been starting the engine with easy start when you turn the engine of for a min. it wont start again could you please help me what to look for? thanks


First easy start is bad for the motor, it sounds like fuel starvation, could be a bad delivery pump in the tank, check in the fuel filter, any aliminium powder in the bottom (it should be brim full of fuel) it a tel tale of a bad pump. They are available cheaper on ebay.

Engine won't turn over completely


You need to replace the Starter and Solinoid. The Solinoid comes on the New Starter. The Solinoid shorted out when the Battery Died and Damaged the Starter.

could be a few things, the main relay under the dash is a common supect it is bolted to a braket next to the stearing colum and they cost about $50.this controls the ignition, fuel pump and some others check it out, next time it stalls and wont start check to see if you are missing the fuel pump or spark and sometimes if its both and you smack this relay itll start right up and its good for another key cycle please rate -jeff
