    Fuel Pump Problem on 2004 Jetta 1.8T

    My engine was running a bit rough some times a little jerk when I got around 2,900 RPMS. I replaced the spark plugs in it and that seemed to have fixed the problem. Recently though, My engine occasionally cuts out, stops running, like it's out of gas. This lasts for a few seconds then the engine comes back on. I am thinking it is either a problem with the coil packs or the fuel pump. What is the likeliest problem? If it's the fuel pump is this something that I could do myself, I'm a student so I'm always trying to save a buck.

    Could possibly be a crankshaft speed sensor. Also known as an impulse sensor. They are common to fail in the 1.8T and 2.0 engines. Check fault codes using vag com and NOT autozone or a generic scanner. sporadic faults do NOT show up on these scanners. Vag com will show you if there is a malfunction for the crank sensor.

    On your engine it's a little bit of a pain to get to. Remove the two 10mm nuts holding the pipe near the dipstick tube. Use two 5mm allens and remove the screws from the manifold. remove the whole vacuum assy out of the way. Now you can see the gray wire for the engine speed sensor. Use a 10mm socket and remove the sensor. Lemme know if that fixes it.

    Hey, I'm going to see if I can find someone who has one. If not I'm going to see if I can buy one, are there any specific models/ types to look for?
