Haynes VW Jetta Rabbit GTI GL 96019 Advance Auto Parts

Is there a possible pin hole in the line that would cause it to suck air? when you fill it past the pin hole it picks up the fuel, just a thot.

Check to make sure you are getting fire. Do you have fuel pressure. There will be valve on the fuel rail (looks like an over sized tire valve) Turn the engine over a few times and push the center part of that valve on the fuel rail (stay clear) Fuel should spray out. If not its either a bad fuel relay or the fuel pump is bad. If you have both fuel and fire, Then do a compression test on all cylinders.If you have no compression, the timing belt may have broke. Hope this helps

Hi the fuel pump is located under the back seats , and under the flap of carpet is a round disc with three screws ! And underneath that you will find a big plastic ring which holds the fuel pump !! They are easy to take out and replace plug and play really ;) Disconnect the battery !! First and be careful please !! Good luck

look in boot space on the same side Rear fender where the fuel tank cap lid is located where the fuel tank cap is located exactly on the same side inside the boot you will find cable which unable you to operate or open the fuel tank cap lid mechanical from inside when you pull the cable it let's open the fuel tank cap from outside see for the instruction manual for more detail or just visit the nearest VW authorised service centre for hazel free driving do keep in writing for more queries

it should be on a sticker on the inside of your door jamb

It may be a coolant temperature sensor they are known for that problem.. A cheap repair if the problem

check the oil around your cylinder head or check your oil if it has water in it

Hi; Did you get this fix yet?

Cheers

It is on the passenger side right behind the washer fluid fill tube. You can follow the fuel lines (look like 1/4" black tubes, some are clear) from the injector pump to it. It is a caniser a bit bigger than a normal looking oil filter and sits between the washer bottle and the metal that forms the wheel well. It is held in by a screw type clamp about half way down the cylinder. Probably isn't the fuel filter unless there is air in the lines to the injector pump or they didn't bother to fill the fuel filter up with diesel after putting it in. There is not a fuel pump in the tank in these cars so everything is sucked up by the injector pump and it needs to be primed properly.
